Return a result list for the given result set.

getResultList

public com.solarmetric.rd.rop.ResultList getResultList(java.sql.Connection conn,
                                                       java.sql.Statement stmnt,
                                                       java.sql.ResultSet rs,

supportsRandomAccess

public boolean supportsRandomAccess(java.lang.Object input)

Description copied from interface: ResultObjectProvider

If the input supports random access, return true.

Specified by:

supportsRandomAccess in interface ResultObjectProvider

setFetchBatchSize

public void setFetchBatchSize(java.lang.Object input,
                              int fetchBatchSize)

Description copied from interface: ResultObjectProvider

Set the batch size to fetch at once. Implementations may ignore this setting. This method will be called before ResultObjectProvider.open(java.lang.Object).

Specified by:

setFetchBatchSize in interface ResultObjectProvider

getResultObject

public java.lang.Object getResultObject(java.lang.Object input)

Description copied from interface: ResultObjectProvider

Instantiate the desired object from the current data in input.

Specified by:

getResultObject in interface ResultObjectProvider

open

public boolean open(java.lang.Object input)

Description copied from interface: ResultObjectProvider

Open the input source input. This is invoked before any data is loaded from the input. Return true if there is data in the input; otherwise false.

Specified by:

open in interface ResultObjectProvider

advance

public boolean advance(java.lang.Object input)

Description copied from interface: ResultObjectProvider

Advance the input source input to the next position. Return true if there is more data; otherwise false. This is invoked between each invocation of ResultObjectProvider.getResultObject(java.lang.Object).

Specified by:

advance in interface ResultObjectProvider

absolute

public boolean absolute(java.lang.Object input,
                        int pos)

Description copied from interface: ResultObjectProvider

Move to the given 0-based input item. This method is only called for providers that support random access. Return true if there is data at this position; otherwise false. This may be invoked in place of ResultObjectProvider.advance(java.lang.Object).

Specified by:

absolute in interface ResultObjectProvider

size

public int size(java.lang.Object input)

Description copied from interface: ResultObjectProvider

Return the number of items in the input, or Integer.MAX_VALUE if the size is unknown.

Specified by:

size in interface ResultObjectProvider

free

public void free(java.lang.Object input)

Description copied from interface: ResultObjectProvider

Optionally free the resources associated with this provider. For example, the source Connection might be released once the statement has been completed, or an InputStream might be closed.

Specified by:

free in interface ResultObjectProvider
