Constructor Detail

CachedRowSetImpl

public CachedRowSetImpl()
                 throws java.sql.SQLException
Constructs a new default CachedRowSetImpl object with the capacity to hold 100 rows. This new object has no metadata and has the following default values:
     onInsertRow = false
     insertRow = null
     cursorPos = 0
     numRows = 0
     showDeleted = false
     queryTimeout = 0
     maxRows = 0
     maxFieldSize = 0
     rowSetType = ResultSet.TYPE_SCROLL_INSENSITIVE
     concurrency = ResultSet.CONCUR_UPDATABLE
     readOnly = false
     isolation = Connection.TRANSACTION_READ_COMMITTED
     escapeProcessing = true
     onInsertRow = false
     insertRow = null
     cursorPos = 0
     absolutePos = 0
     numRows = 0
 
A CachedRowSetImpl object is configured to use the default RIOptimisticProvider implementation to provide connectivity and synchronization capabilities to the set data source.

Throws:
java.sql.SQLException - if an error occurs

CachedRowSetImpl

public CachedRowSetImpl(java.util.Hashtable env)
                 throws java.sql.SQLException
Provides a CachedRowSetImpl instance with the same default properties as as the zero parameter constructor.
     onInsertRow = false
     insertRow = null
     cursorPos = 0
     numRows = 0
     showDeleted = false
     queryTimeout = 0
     maxRows = 0
     maxFieldSize = 0
     rowSetType = ResultSet.TYPE_SCROLL_INSENSITIVE
     concurrency = ResultSet.CONCUR_UPDATABLE
     readOnly = false
     isolation = Connection.TRANSACTION_READ_COMMITTED
     escapeProcessing = true
     onInsertRow = false
     insertRow = null
     cursorPos = 0
     absolutePos = 0
     numRows = 0
 
However, applications will have the means to specify at runtime the desired SyncProvider object.

For example, creating a CachedRowSetImpl object as follows ensures that a it is established with the com.foo.provider.Impl synchronization implementation providing the synchronization mechanism for this disconnected RowSet object.

     Hashtable env = new Hashtable();
     env.put(javax.sql.rowset.spi.SyncFactory.ROWSET_PROVIDER_NAME,
         "com.foo.provider.Impl");
     CachedRowSetImpl crs = new CachedRowSet(env);
 

Calling this constructor with a null parameter will cause the SyncFactory to provide the reference optimistic provider com.sun.rowset.providers.RIOptimisticProvider.

In addition, the following properties can be associated with the provider to assist in determining the choice of the synchronizaton provider such as:

More specific detailes are available in the SyncFactory and SyncProvider specificiations later in this document.

Parameters:
env - a Hashtable object with a list of desired synchronization providers
Throws:
java.sql.SQLException - if the requested provider cannot be found by the synchonization factory
See Also:
SyncProvider
Method Detail

setCommand

public void setCommand(java.lang.String cmd)
                throws java.sql.SQLException
Sets this CachedRowSetImpl object's command property to the given String object and clears the parameters, if any, that were set for the previous command.

The command property may not be needed if the rowset is produced by a data source, such as a spreadsheet, that does not support commands. Thus, this property is optional and may be null.

Specified by:
setCommand in interface javax.sql.RowSet
Overrides:
setCommand in class BaseRowSet
Parameters:
cmd - a String object containing an SQL query that will be set as the command; may be null
Throws:
java.sql.SQLException - if an error occurs
See Also:
BaseRowSet.getCommand()

populate

public void populate(java.sql.ResultSet data)
              throws java.sql.SQLException
Populates this CachedRowSetImpl object with data from the given ResultSet object. This method is an alternative to the method execute for filling the rowset with data. The method populate does not require that the properties needed by the method execute, such as the command property, be set. This is true because the method populate is given the ResultSet object from which to get data and thus does not need to use the properties required for setting up a connection and executing this CachedRowSetImpl object's command.

After populating this rowset with data, the method populate sets the rowset's metadata and then sends a RowSetChangedEvent object to all registered listeners prior to returning.

Specified by:
populate in interface CachedRowSet
Parameters:
data - the ResultSet object containing the data to be read into this CachedRowSetImpl object
Throws:
java.sql.SQLException - if an error occurs; or the max row setting is violated while populating the RowSet
See Also:
execute(java.sql.Connection)

execute

public void execute(java.sql.Connection conn)
             throws java.sql.SQLException
Populates this CachedRowSetImpl object with data, using the given connection to produce the result set from which data will be read. A second form of this method, which takes no arguments, uses the values from this rowset's user, password, and either url or data source properties to create a new database connection. The form of execute that is given a connection ignores these properties.

Specified by:
execute in interface CachedRowSet
Parameters:
conn - A standard JDBC Connection object that this CachedRowSet object can pass to a synchronization provider to establish a connection to the data source
Throws:
java.sql.SQLException - if an invalid Connection is supplied or an error occurs in establishing the connection to the data source
See Also:
populate(java.sql.ResultSet), Connection

acceptChanges

public void acceptChanges()
                   throws SyncProviderException
Propagates all row update, insert, and delete changes to the underlying data source backing this CachedRowSetImpl object.

NoteIn the reference implementation an optimistic concurrency implementation is provided as a sample implementation of a the SyncProvider abstract class.

This method fails if any of the updates cannot be propagated back to the data source. When it fails, the caller can assume that none of the updates are reflected in the data source. When an exception is thrown, the current row is set to the first "updated" row that resulted in an exception unless the row that caused the exception is a "deleted" row. In that case, when deleted rows are not shown, which is usually true, the current row is not affected.

If no SyncProvider is configured, the reference implementation leverages the RIOptimisticProvider available which provides the default and reference synchronization capabilities for disconnected RowSets.

Specified by:
acceptChanges in interface CachedRowSet
Throws:
java.sql.SQLException - if the cursor is on the insert row or the underlying reference synchronization provider fails to commit the updates to the datasource
SyncProviderException - if an internal error occurs within the SyncProvider instance during either during the process or at any time when the SyncProvider instance touches the data source.
See Also:
acceptChanges(java.sql.Connection), RowSetWriter, SyncProvider

acceptChanges

public void acceptChanges(java.sql.Connection con)
                   throws SyncProviderException
Propagates all row update, insert, and delete changes to the data source backing this CachedRowSetImpl object using the given Connection object.

The reference implementation RIOptimisticProvider modifies its synchronization to a write back function given the updated connection The reference implementation modifies its synchronization behaviour via the SyncProvider to ensure the synchronization occurs according to the updated JDBC Connection properties.

Specified by:
acceptChanges in interface CachedRowSet
Parameters:
con - a standard JDBC Connection object
Throws:
java.sql.SQLException - if the cursor is on the insert row or the underlying synchronization provider fails to commit the updates back to the data source
SyncProviderException - if the underlying synchronization provider's writer fails to write the updates back to the data source
See Also:
acceptChanges(), RowSetWriter, SyncFactory, SyncProvider

restoreOriginal

public void restoreOriginal()
                     throws java.sql.SQLException
Restores this CachedRowSetImpl object to its original state, that is, its state before the last set of changes.

Before returning, this method moves the cursor before the first row and sends a rowSetChanged event to all registered listeners.

Specified by:
restoreOriginal in interface CachedRowSet
Throws:
java.sql.SQLException - if an error is occurs rolling back the RowSet state to the definied original value.
See Also:
RowSetListener.rowSetChanged(javax.sql.RowSetEvent)

release

public void release()
             throws java.sql.SQLException
Releases the current contents of this CachedRowSetImpl object and sends a rowSetChanged event object to all registered listeners.

Specified by:
release in interface CachedRowSet
Throws:
java.sql.SQLException - if an error occurs flushing the contents of RowSet.
See Also:
RowSetListener.rowSetChanged(javax.sql.RowSetEvent)

undoDelete

public void undoDelete()
                throws java.sql.SQLException
Cancels deletion of the current row and notifies listeners that a row has changed.

Note: This method can be ignored if deleted rows are not being shown, which is the normal case.

Specified by:
undoDelete in interface CachedRowSet
Throws:
java.sql.SQLException - if the cursor is not on a valid row
See Also:
CachedRowSet.undoInsert(), ResultSet.cancelRowUpdates()

undoInsert

public void undoInsert()
                throws java.sql.SQLException
Immediately removes the current row from this CachedRowSetImpl object if the row has been inserted, and also notifies listeners the a row has changed. An exception is thrown if the row is not a row that has been inserted or the cursor is before the first row, after the last row, or on the insert row.

This operation cannot be undone.

Specified by:
undoInsert in interface CachedRowSet
Throws:
java.sql.SQLException - if an error occurs, the cursor is not on a valid row, or the row has not been inserted
See Also:
CachedRowSet.undoDelete(), ResultSet.cancelRowUpdates()

undoUpdate

public void undoUpdate()
                throws java.sql.SQLException
Immediately reverses the last update operation if the row has been modified. This method can be called to reverse updates on a all columns until all updates in a row have been rolled back to their originating state since the last synchronization (acceptChanges) or population. This method may also be called while performing updates to the insert row.

undoUpdate

Specified by:
undoUpdate in interface CachedRowSet
Throws:
java.sql.SQLException - if cursor is before the first row, after the last row in rowset.
See Also:
undoDelete(), undoInsert(), ResultSet.cancelRowUpdates()

createShared

public javax.sql.RowSet createShared()
                              throws java.sql.SQLException
Returns a new RowSet object backed by the same data as that of this CachedRowSetImpl object and sharing a set of cursors with it. This allows cursors to interate over a shared set of rows, providing multiple views of the underlying data.

Specified by:
createShared in interface CachedRowSet
Returns:
a RowSet object that is a copy of this CachedRowSetImpl object and shares a set of cursors with it
Throws:
java.sql.SQLException - if an error occurs or cloning is not supported
See Also:
RowSetEvent, RowSetListener

clone

protected java.lang.Object clone()
                          throws java.lang.CloneNotSupportedException
Returns a new RowSet object containing by the same data as this CachedRowSetImpl object. This method differs from the method createCopy in that it throws a CloneNotSupportedException object instead of an SQLException object, as the method createShared does. This clone method is called internally by the method createShared, which catches the CloneNotSupportedException object and in turn throws a new SQLException object.

Returns:
a copy of this CachedRowSetImpl object
Throws:
java.lang.CloneNotSupportedException - if an error occurs when attempting to clone this CachedRowSetImpl object
See Also:
createShared()

createCopy

public CachedRowSet createCopy()
                        throws java.sql.SQLException
Creates a RowSet object that is a deep copy of this CachedRowSetImpl object's data, including constraints. Updates made on a copy are not visible to the original rowset; a copy of a rowset is completely independent from the original.

Making a copy saves the cost of creating an identical rowset from first principles, which can be quite expensive. For example, it can eliminate the need to query a remote database server.

Specified by:
createCopy in interface CachedRowSet
Returns:
a new CachedRowSet object that is a deep copy of this CachedRowSet object and is completely independent from this CachedRowSetImpl object.
Throws:
java.sql.SQLException - if an error occurs in generating the copy of this of the CachedRowSetImpl
See Also:
createShared(), RowSetEvent, RowSetListener

createCopySchema

public CachedRowSet createCopySchema()
                              throws java.sql.SQLException
Creates a RowSet object that is a copy of this CachedRowSetImpl object's table structure and the constraints only. There will be no data in the object being returned. Updates made on a copy are not visible to the original rowset.

This helps in getting the underlying XML schema which can be used as the basis for populating a WebRowSet.

Specified by:
createCopySchema in interface CachedRowSet
Returns:
a new CachedRowSet object that is a copy of this CachedRowSetImpl object's schema and retains all the constraints on the original rowset but contains no data
Throws:
java.sql.SQLException - if an error occurs in generating the copy of the CachedRowSet object
See Also:
createShared(), createCopy(), createCopyNoConstraints(), RowSetEvent, RowSetListener

createCopyNoConstraints

public CachedRowSet createCopyNoConstraints()
                                     throws java.sql.SQLException
Creates a CachedRowSet object that is a copy of this CachedRowSetImpl object's data only. All constraints set in this object will not be there in the returning object. Updates made on a copy are not visible to the original rowset.

Specified by:
createCopyNoConstraints in interface CachedRowSet
Returns:
a new CachedRowSet object that is a deep copy of this CachedRowSetImpl object and is completely independent from this CachedRowSetImpl object
Throws:
java.sql.SQLException - if an error occurs in generating the copy of the of the CachedRowSet
See Also:
createShared(), createCopy(), createCopySchema(), RowSetEvent, RowSetListener

Specified by:
toCollection in interface CachedRowSet
Returns:
a Collection object consisting of tables, each of which is a copy of a row in this CachedRowSetImpl object
Throws:
java.sql.SQLException - if an error occurs in generating the collection
See Also:
toCollection(int), toCollection(String), TreeMap

toCollection

public java.util.Collection toCollection(int column)
                                  throws java.sql.SQLException
Returns the specified column of this CachedRowSetImpl object as a Collection object. This method makes a copy of the column's data and utilitizes the Vector to establish the collection. The Vector class implements a growable array objects allowing the individual components to be accessed using an an integer index similar to that of an array.

Specified by:
toCollection in interface CachedRowSet
Parameters:
column - an int indicating the column whose values are to be represented in a Collection object
Returns:
a Collection object that contains the value(s) stored in the specified column of this CachedRowSetImpl object

getSyncProvider

public SyncProvider getSyncProvider()
                             throws java.sql.SQLException
Returns the SyncProvider implementation being used with this CachedRowSetImpl implementation rowset.

Specified by:
getSyncProvider in interface CachedRowSet
Returns:
the SyncProvider used by the rowset. If not provider was set when the rowset was instantiated, the reference implementation (default) provider is returned.
Throws:
java.sql.SQLException - if error occurs while return the SyncProvider instance.
See Also:
CachedRowSet.setSyncProvider(java.lang.String)

setSyncProvider

public void setSyncProvider(java.lang.String providerStr)

Sets the active SyncProvider and attempts to load load the new provider using the SyncFactory SPI.

Specified by:
setSyncProvider in interface CachedRowSet
Parameters:
providerStr - a String object giving the fully qualified class name of a SyncProvider implementation
Throws:
java.sql.SQLException - if an error occurs while resetting the SyncProvider.
See Also:
CachedRowSet.getSyncProvider()

execute

public void execute()
             throws java.sql.SQLException
Populates this CachedRowSetImpl object with data. This form of the method uses the rowset's user, password, and url or data source name properties to create a database connection. If properties that are needed have not been set, this method will throw an exception.

Another form of this method uses an existing JDBC Connection object instead of creating a new one; therefore, it ignores the properties used for establishing a new connection.

The query specified by the command property is executed to create a ResultSet object from which to retrieve data. The current contents of the rowset are discarded, and the rowset's metadata is also (re)set. If there are outstanding updates, they are also ignored.

The method execute closes any database connections that it creates.

Specified by:
execute in interface javax.sql.RowSet
Throws:
java.sql.SQLException - if an error occurs or the necessary properties have not been set

next

public boolean next()
             throws java.sql.SQLException
Moves the cursor down one row from its current position and returns true if the new cursor position is a valid row. The cursor for a new ResultSet object is initially positioned before the first row. The first call to the method next moves the cursor to the first row, making it the current row; the second call makes the second row the current row, and so on.

If an input stream from the previous row is open, it is implicitly closed. The ResultSet object's warning chain is cleared when a new row is read.

Specified by:
next in interface java.sql.ResultSet
Returns:
true if the new current row is valid; false if there are no more rows
Throws:
java.sql.SQLException - if an error occurs or the cursor is not positioned in the rowset, before the first row, or after the last row

internalNext

protected boolean internalNext()
                        throws java.sql.SQLException
Moves this CachedRowSetImpl object's cursor to the next row and returns true if the cursor is still in the rowset; returns false if the cursor has moved to the position after the last row.

This method handles the cases where the cursor moves to a row that has been deleted. If this rowset shows deleted rows and the cursor moves to a row that has been deleted, this method moves the cursor to the next row until the cursor is on a row that has not been deleted.

The method internalNext is called by methods such as next, absolute, and relative, and, as its name implies, is only called internally.

This is a implementation only method and is not required as a standard implementation of the CachedRowSet interface.

Returns:
true if the cursor is on a valid row in this rowset; false if it is after the last row
Throws:
java.sql.SQLException - if an error occurs

close

public void close()
           throws java.sql.SQLException
Closes this CachedRowSetImpl objecy and releases any resources it was using.

Specified by:
close in interface java.sql.ResultSet
Throws:
java.sql.SQLException - if an error occurs when releasing any resources in use by this CachedRowSetImpl object

wasNull

public boolean wasNull()
                throws java.sql.SQLException
Reports whether the last column read was SQL NULL. Note that you must first call the method getXXX on a column to try to read its value and then call the method wasNull to determine whether the value was SQL NULL.

Specified by:
wasNull in interface java.sql.ResultSet
Returns:
true if the value in the last column read was SQL NULL; false otherwise
Throws:
java.sql.SQLException - if an error occurs

getCurrentRow

protected BaseRow getCurrentRow()
Returns the insert row or the current row of this CachedRowSetImplobject.

Returns:
the Row object on which this CachedRowSetImpl objects's cursor is positioned

removeCurrentRow

protected void removeCurrentRow()
Removes the row on which the cursor is positioned.

This is a implementation only method and is not required as a standard implementation of the CachedRowSet interface.

Throws:
java.sql.SQLException - if the cursor is positioned on the insert row

                               throws java.sql.SQLException
Retrieves the name of the SQL cursor used by this CachedRowSetImpl object.

In SQL, a result table is retrieved through a cursor that is named. The current row of a ResultSet can be updated or deleted using a positioned update/delete statement that references the cursor name. To ensure that the cursor has the proper isolation level to support an update operation, the cursor's SELECT statement should be of the form select for update. If the for update clause is omitted, positioned updates may fail.

JDBC supports this SQL feature by providing the name of the SQL cursor used by a ResultSet object. The current row of a result set is also the current row of this SQL cursor.

Note: If positioned updates are not supported, an SQLException is thrown.

Specified by:
getCursorName in interface java.sql.ResultSet
Returns:
the SQL cursor name for this CachedRowSetImpl object's cursor
Throws:
java.sql.SQLException - if an error occurs

getObject

public java.lang.Object getObject(int columnIndex)
                           throws java.sql.SQLException
Retrieves the value of the designated column in the current row of this CachedRowSetImpl object as an Object value.

The type of the Object will be the default Java object type corresponding to the column's SQL type, following the mapping for built-in types specified in the JDBC 3.0 specification.

This method may also be used to read datatabase-specific abstract data types.

This implementation of the method getObject extends its behavior so that it gets the attributes of an SQL structured type as an array of Object values. This method also custom maps SQL user-defined types to classes in the Java programming language. When the specified column contains a structured or distinct value, the behavior of this method is as if it were a call to the method getObject(columnIndex, this.getStatement().getConnection().getTypeMap()).

Specified by:
getObject in interface java.sql.ResultSet
Parameters:
columnIndex - the first column is 1, the second is 2, and so on; must be 1 or larger and equal to or less than the number of columns in the rowset
Returns:
a java.lang.Object holding the column value; if the value is SQL NULL, the result is null
Throws:
java.sql.SQLException - if the given column index is out of bounds, the cursor is not on a valid row, or there is a problem getting the Class object for a custom mapping

java.sql.SQLException - if an error occurs

isLast

public boolean isLast()
               throws java.sql.SQLException
Indicates whether the cursor is on the last row in this CachedRowSetImpl object.

Note: Calling the method isLast may be expensive because the JDBC driver might need to fetch ahead one row in order to determine whether the current row is the last row in this rowset.

Specified by:
isLast in interface java.sql.ResultSet
Returns:
true if the cursor is on the last row; false otherwise or if this rowset contains no rows
Throws:
java.sql.SQLException - if an error occurs

beforeFirst

public void beforeFirst()
                 throws java.sql.SQLException
Moves this CachedRowSetImpl object's cursor to the front of the rowset, just before the first row. This method has no effect if this rowset contains no rows.

Specified by:
beforeFirst in interface java.sql.ResultSet
Throws:
java.sql.SQLException - if an error occurs or the type of this rowset is ResultSet.TYPE_FORWARD_ONLY

afterLast

public void afterLast()
               throws java.sql.SQLException
Moves this CachedRowSetImpl object's cursor to the end of the rowset, just after the last row. This method has no effect if this rowset contains no rows.

Specified by:

Throws:
java.sql.SQLException - if an error occurs

first

public boolean first()
              throws java.sql.SQLException
Moves this CachedRowSetImpl object's cursor to the first row and returns true if the operation was successful. This method also notifies registered listeners that the cursor has moved.

Specified by:
first in interface java.sql.ResultSet
Returns:
true if the cursor is on a valid row; false otherwise or if there are no rows in this CachedRowSetImpl object
Throws:
java.sql.SQLException - if the type of this rowset is ResultSet.TYPE_FORWARD_ONLY

internalFirst

protected boolean internalFirst()
                         throws java.sql.SQLException
Moves this CachedRowSetImpl object's cursor to the first row and returns true if the operation is successful.

This method is called internally by the methods first, isFirst, and absolute. It in turn calls the method internalNext in order to handle the case where the first row is a deleted row that is not visible.

This is a implementation only method and is not required as a standard implementation of the CachedRowSet interface.

Returns:
true if the cursor moved to the first row; false otherwise
Throws:
java.sql.SQLException - if an error occurs

last

public boolean last()
             throws java.sql.SQLException
Moves this CachedRowSetImpl object's cursor to the last row and returns true if the operation was successful. This method also notifies registered listeners that the cursor has moved.

Specified by:
last in interface java.sql.ResultSet
Returns:
true if the cursor is on a valid row; false otherwise or if there are no rows in this CachedRowSetImpl object
Throws:
java.sql.SQLException - if the type of this rowset is ResultSet.TYPE_FORWARD_ONLY

internalLast

protected boolean internalLast()
                        throws java.sql.SQLException
Moves this CachedRowSetImpl object's cursor to the last row and returns true if the operation is successful.

This method is called internally by the method last when rows have been deleted and the deletions are not visible. The method internalLast handles the case where the last row is a deleted row that is not visible by in turn calling the method internalPrevious.

This is a implementation only method and is not required as a standard implementation of the CachedRowSet interface.

Returns:
true if the cursor moved to the last row; false otherwise
Throws:
java.sql.SQLException - if an error occurs

getRow

public int getRow()
           throws java.sql.SQLException
Returns the number of the current row in this CachedRowSetImpl object. The first row is number 1, the second number 2, and so on.

Specified by:
getRow in interface java.sql.ResultSet
Returns:
the number of the current row; 0 if there is no current row
Throws:
java.sql.SQLException - if an error occurs; or if the CacheRowSetImpl is empty

absolute

public boolean absolute(int row)
                 throws java.sql.SQLException
Moves this CachedRowSetImpl object's cursor to the row number specified.

If the number is positive, the cursor moves to an absolute row with respect to the beginning of the rowset. The first row is row 1, the second is row 2, and so on. For example, the following command, in which crs is a CachedRowSetImpl object, moves the cursor to the fourth row, starting from the beginning of the rowset.



    crs.absolute(4);

  

If the number is negative, the cursor moves to an absolute row position with respect to the end of the rowset. For example, calling absolute(-1) positions the cursor on the last row, absolute(-2) moves it on the next-to-last row, and so on. If the CachedRowSetImpl object crs has five rows, the following command moves the cursor to the fourth-to-last row, which in the case of a rowset with five rows, is also the second row, counting from the beginning.



    crs.absolute(-4);

  
If the number specified is larger than the number of rows, the cursor will move to the position after the last row. If the number specified would move the cursor one or more rows before the first row, the cursor moves to the position before the first row.

Note: Calling absolute(1) is the same as calling the method first(). Calling absolute(-1) is the same as calling last().

Specified by:
absolute in interface java.sql.ResultSet
Parameters:
row - a positive number to indicate the row, starting row numbering from the first row, which is 1; a negative number to indicate the row, starting row numbering from the last row, which is -1; it must not be 0
Returns:
true if the cursor is on the rowset; false otherwise
Throws:
java.sql.SQLException - if the given cursor position is 0 or the type of this rowset is ResultSet.TYPE_FORWARD_ONLY

relative

public boolean relative(int rows)
                 throws java.sql.SQLException
Moves the cursor the specified number of rows from the current position, with a positive number moving it forward and a negative number moving it backward.

If the number is positive, the cursor moves the specified number of rows toward the end of the rowset, starting at the current row. For example, the following command, in which crs is a CachedRowSetImpl object with 100 rows, moves the cursor forward four rows from the current row. If the current row is 50, the cursor would move to row 54.



    crs.relative(4);

  

If the number is negative, the cursor moves back toward the beginning the specified number of rows, starting at the current row. For example, calling the method absolute(-1) positions the cursor on the last row, absolute(-2) moves it on the next-to-last row, and so on. If the CachedRowSetImpl object crs has five rows, the following command moves the cursor to the fourth-to-last row, which in the case of a rowset with five rows, is also the second row from the beginning.



    crs.absolute(-4);

  
If the number specified is larger than the number of rows, the cursor will move to the position after the last row. If the number specified would move the cursor one or more rows before the first row, the cursor moves to the position before the first row. In both cases, this method throws an SQLException.

Note: Calling absolute(1) is the same as calling the method first(). Calling absolute(-1) is the same as calling last(). Calling relative(0) is valid, but it does not change the cursor position.

Specified by:
relative in interface java.sql.ResultSet
Parameters:
rows - an int indicating the number of rows to move the cursor, starting at the current row; a positive number moves the cursor forward; a negative number moves the cursor backward; must not move the cursor past the valid rows
Returns:
true if the cursor is on a row in this CachedRowSetImpl object; false otherwise
Throws:
java.sql.SQLException - if there are no rows in this rowset, the cursor is positioned either before the first row or after the last row, or the rowset is type ResultSet.TYPE_FORWARD_ONLY

previous

public boolean previous()
                 throws java.sql.SQLException
Moves this CachedRowSetImpl object's cursor to the previous row and returns true if the cursor is on a valid row or false if it is not. This method also notifies all listeners registered with this CachedRowSetImpl object that its cursor has moved.

Note: calling the method previous() is not the same as calling the method relative(-1). This is true because it is possible to call previous() from the insert row, from after the last row, or from the current row, whereas relative may only be called from the current row.

The method previous may used in a while loop to iterate through a rowset starting after the last row and moving toward the beginning. The loop ends when previous returns false, meaning that there are no more rows. For example, the following code fragment retrieves all the data in the CachedRowSetImpl object crs, which has three columns. Note that the cursor must initially be positioned after the last row so that the first call to the method previous places the cursor on the last line.

 

     crs.afterLast();
     while (previous()) {
         String name = crs.getString(1);
         int age = crs.getInt(2);
         short ssn = crs.getShort(3);
         System.out.println(name + "   " + age + "   " + ssn);
     }

  
This method throws an SQLException if the cursor is not on a row in the rowset, before the first row, or after the last row.

Specified by:
previous in interface java.sql.ResultSet
Returns:
true if the cursor is on a valid row; false if it is before the first row or after the last row
Throws:
java.sql.SQLException - if the cursor is not on a valid position or the type of this rowset is ResultSet.TYPE_FORWARD_ONLY

internalPrevious

protected boolean internalPrevious()
                            throws java.sql.SQLException
Moves the cursor to the previous row in this CachedRowSetImpl object, skipping past deleted rows that are not visible; returns true if the cursor is on a row in this rowset and false when the cursor goes before the first row.

This method is called internally by the method previous.

This is a implementation only method and is not required as a standard implementation of the CachedRowSet interface.

Returns:
true if the cursor is on a row in this rowset; false when the cursor reaches the position before the first row
Throws:
java.sql.SQLException - if an error occurs

rowUpdated

public boolean rowUpdated()
                   throws java.sql.SQLException
Indicates whether the current row of this CachedRowSetImpl object has been updated. The value returned depends on whether this rowset can detect updates: false will always be returned if it does not detect updates.

Specified by:
rowUpdated in interface java.sql.ResultSet
Returns:
true if the row has been visibly updated by the owner or another and updates are detected; false otherwise

If the current row is the position after the last row or before the first row, the new row will be inserted at the end of the rowset. This method also notifies listeners registered with this rowset that the row has changed.

The cursor must be on the insert row when this method is called.

Specified by:
insertRow in interface java.sql.ResultSet
Throws:
java.sql.SQLException - if (1) the cursor is not on the insert row, (2) one or more of the non-nullable columns in the insert row has not been given a value, or (3) this rowset is ResultSet.CONCUR_READ_ONLY

updateRow

public void updateRow()
               throws java.sql.SQLException
Marks the current row of this CachedRowSetImpl object as updated and notifies listeners registered with this rowset that the row has changed.

This method cannot be called when the cursor is on the insert row, and it should be called before the cursor moves to another row. If it is called after the cursor moves to another row, this method has no effect, and the updates made before the cursor moved will be lost.

Specified by:
updateRow in interface java.sql.ResultSet
Throws:
java.sql.SQLException - if the cursor is on the insert row or this rowset is ResultSet.CONCUR_READ_ONLY

deleteRow

public void deleteRow()
               throws java.sql.SQLException
Deletes the current row from this CachedRowSetImpl object and notifies listeners registered with this rowset that a row has changed. This method cannot be called when the cursor is on the insert row.

This method marks the current row as deleted, but it does not delete the row from the underlying data source. The method acceptChanges must be called to delete the row in the data source.

Specified by:
deleteRow in interface java.sql.ResultSet
Throws:
java.sql.SQLException - if (1) this method is called when the cursor is on the insert row, before the first row, or after the last row or (2) this rowset is ResultSet.CONCUR_READ_ONLY

refreshRow

public void refreshRow()
                throws java.sql.SQLException
Sets the current row with its original value and marks the row as not updated, thus undoing any changes made to the row since the last call to the methods updateRow or deleteRow. This method should be called only when the cursor is on a row in this rowset.

Specified by:
refreshRow in interface java.sql.ResultSet
Throws:
java.sql.SQLException - if the cursor is on the insert row, before the first row, or after the last row

cancelRowUpdates

public void cancelRowUpdates()
                      throws java.sql.SQLException
Rolls back any updates made to the current row of this CachedRowSetImpl object and notifies listeners that a row has changed. To have an effect, this method must be called after an updateXXX method has been called and before the method updateRow has been called. If no updates have been made or the method updateRow has already been called, this method has no effect.

Specified by:
cancelRowUpdates in interface java.sql.ResultSet
Throws:
java.sql.SQLException - if the cursor is on the insert row, before the first row, or after the last row

moveToInsertRow

public void moveToInsertRow()
                     throws java.sql.SQLException
Moves the cursor for this CachedRowSetImpl object to the insert row. The current row in the rowset is remembered while the cursor is on the insert row.

The insert row is a special row associated with an updatable rowset. It is essentially a buffer where a new row may be constructed by calling the appropriate updateXXX methods to assign a value to each column in the row. A complete row must be constructed; that is, every column that is not nullable must be assigned a value. In order for the new row to become part of this rowset, the method insertRow must be called before the cursor is moved back to the rowset.

Only certain methods may be invoked while the cursor is on the insert row; many methods throw an exception if they are called while the cursor is there. In addition to the updateXXX and insertRow methods, only the getXXX methods may be called when the cursor is on the insert row. A getXXX method should be called on a column only after an updateXXX method has been called on that column; otherwise, the value returned is undetermined.

Specified by:
moveToInsertRow in interface java.sql.ResultSet
Throws:
java.sql.SQLException - if this CachedRowSetImpl object is ResultSet.CONCUR_READ_ONLY

moveToCurrentRow

public void moveToCurrentRow()
                      throws java.sql.SQLException

rowSetPopulated

public void rowSetPopulated(javax.sql.RowSetEvent event,
                            int numRows)
                     throws java.sql.SQLException
Notifies registered listeners that a RowSet object in the given RowSetEvent object has populated a number of additional rows. The numRows parameter ensures that this event will only be fired every numRow.

The source of the event can be retrieved with the method event.getSource.

Specified by:
rowSetPopulated in interface CachedRowSet
Parameters:
event - a RowSetEvent object that contains the RowSet object that is the source of the events
numRows - when populating, the number of rows interval on which the CachedRowSet populated should fire; the default value is zero; cannot be less than fetchSize or zero
Throws:
java.sql.SQLException

populate

public void populate(java.sql.ResultSet data,
                     int start)
              throws java.sql.SQLException
Populates this CachedRowSet object with data from the given ResultSet object. While related to the populate(ResultSet) method, an additional parameter is provided to allow starting position within the ResultSet from where to populate the CachedRowSet instance. This method is an alternative to the method execute for filling the rowset with data. The method populate does not require that the properties needed by the method execute, such as the command property, be set. This is true because the method populate is given the ResultSet object from which to get data and thus does not need to use the properties required for setting up a connection and executing this CachedRowSetImpl object's command.

After populating this rowset with data, the method populate sets the rowset's metadata and then sends a RowSetChangedEvent object to all registered listeners prior to returning.

Specified by:
populate in interface CachedRowSet
Parameters:
data - the ResultSet object containing the data to be read into this CachedRowSetImpl object
start - the integer specifing the position in the ResultSet object to popultate the CachedRowSetImpl object.
Throws:
java.sql.SQLException - if an error occurs; or the max row setting is violated while populating the RowSet.Also id the start position is negative.

execute(java.sql.Connection)

nextPage

public boolean nextPage()
                 throws java.sql.SQLException
The nextPage gets the next page, that is a CachedRowSetImpl object containing the number of rows specified by page size.

Specified by:
nextPage in interface CachedRowSet
Returns:
boolean value true indicating whether there are more pages to come and false indicating that this is the last page.
Throws:
java.sql.SQLException - if an error occurs or this called before calling populate.

setPageSize

public void setPageSize(int size)
                 throws java.sql.SQLException
This is the setter function for setting the size of the page, which specifies how many rows have to be retrived at a time.

Specified by:
setPageSize in interface CachedRowSet
Parameters:
size - which is the page size
Throws:
java.sql.SQLException - if size is less than zero or greater than max rows.

getPageSize

public int getPageSize()
This is the getter function for the size of the page.

Specified by:
getPageSize in interface CachedRowSet
Returns:
an integer that is the page size.

previousPage

public boolean previousPage()
                     throws java.sql.SQLException
Retrieves the data present in the page prior to the page from where it is called.

Specified by:
previousPage in interface CachedRowSet
Returns:
boolean value true if it retrieves the previous page, flase if it is on the first page.
Throws:
java.sql.SQLException - if it is called before populate is called or ResultSet is of type ResultSet.TYPE_FORWARD_ONLY or if an error occurs.
