Constructor Detail

ColumnCollectionMapping

public ColumnCollectionMapping(com.solarmetric.rd.kodo.meta.FieldMetaData meta)
Constructor. Supply underlying metadata.

Method Detail

getColumn

public com.solarmetric.rd.kodo.impl.jdbc.schema.Column getColumn()
Return the column holding the collection data.


setColumn

public void setColumn(com.solarmetric.rd.kodo.impl.jdbc.schema.Column col)
Set the column holding the collection data.


getDataStoreTypeCode

protected int getDataStoreTypeCode()
Return the type of the value stored in the data store for the element column. Defaults to FieldMetaData.getElementTypeCode().


getJDBCType

protected int getJDBCType()
Return the JDBC Types type of the column for this mapping. Uses the preferred type for the getDataStoreTypeCode() by default.


getJavaValue

protected java.lang.Object getJavaValue(java.lang.Object val,
                                        com.solarmetric.rd.kodo.impl.jdbc.runtime.JDBCStoreManager store,
                                        java.sql.Connection conn)
                                 throws java.sql.SQLException
Return the Java value for the given datastore element value. Returns the given value by default.

java.sql.SQLException

toMappingInfo

public void toMappingInfo(com.solarmetric.rd.kodo.impl.jdbc.meta.MappingInfo info)
Description copied from class: Mapping
Serialize this mapping to a simple MappingInfo instance for transfer to XML or some other format.

Overrides:
toMappingInfo in class AbstractCollectionMapping

fromMappingInfo

public boolean fromMappingInfo(com.solarmetric.rd.kodo.impl.jdbc.meta.MappingInfo info,
                               boolean adapt)
Description copied from class: Mapping
Deserialize this mapping from a simple MappingInfo instance parsed from XML or some other format. If the info is incompatible and adapt is true, try to adapt to the new info, else return false. This method must validate the given mapping information using the SchemaGroup.findTable(java.lang.String) method to find any needed tables, the Table.getColumn(java.lang.String) method to retrieve columns from those tables, and the Column.isCompatible(int, int) method to check all column types. This is important, as some schema groups use these methods to build themselves up dynamically rather than reading schema information from the database.

Overrides:
fromMappingInfo in class AbstractCollectionMapping

map

public boolean map()
Description copied from class: Mapping
Map a new instance of this mapping type. If the underlying metadata cannot be mapped using this type, return false.

Overrides:
map in class ContainerMapping

refSchemaComponents

public void refSchemaComponents()
Description copied from class: Mapping
Increment the reference count of all used schema components.

Overrides:
refSchemaComponents in class AbstractCollectionMapping

getColumns

public com.solarmetric.rd.kodo.impl.jdbc.schema.Column[] getColumns()
Description copied from class: FieldMapping

            throws java.sql.SQLException
Description copied from class: Mapping
Set values for the mapping into the proper rows. For class mappings, this method will be called only after the corresponding method has been called for all fields of this mapping.

Overrides:
insert in class ContainerMapping
java.sql.SQLException

update

public void update(com.solarmetric.rd.kodo.runtime.StateManagerImpl sm,
                   com.solarmetric.rd.kodo.impl.jdbc.runtime.RowManager rm)

                   com.solarmetric.rd.kodo.impl.jdbc.runtime.RowManager rm)
            throws java.sql.SQLException
Description copied from class: Mapping
Set the where values appropriately to delete the proper instance, and set all relations on non-secondary tables as updates. This allows foreign key analysis.

Specified by:

java.sql.SQLException
See Also:
Mapping.insert(com.solarmetric.rd.kodo.runtime.StateManagerImpl, com.solarmetric.rd.kodo.impl.jdbc.runtime.RowManager)
