Constructor Detail

NToPCObjectMapFieldMapping

public NToPCObjectMapFieldMapping(FieldMetaData meta)

Constructor. Supply underlying metadata.

Method Detail

getDataStoreTypeCode

protected int getDataStoreTypeCode()

Description copied from class: ColumnMapFieldMapping

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

Overrides:

getDataStoreTypeCode in class ColumnMapFieldMapping

getDataStoreValue

public Object getDataStoreValue(Object val)

Description copied from interface: FieldMapping

Translate the given external field value to its datastore equivalent. If the mapping occupies multiple columns in the datastore, return an object array, else return a single object. Simply returns the given object by default.

Overrides:

getDataStoreValue in class AbstractFieldMapping

getMappingType

public String getMappingType()

Description copied from interface: Mapping

Return the abbreviated name of this mapping, or the full class name if it is a custom mapping.

fromMappingInfo

public void fromMappingInfo(MappingInfo info,
                            boolean adapt)

Description copied from class: AbstractFieldMapping

The default implementation will raise warnings for any mapping attributes that are declared but not in the list of the valid attributes for this mapping.

Overrides:

fromMappingInfo in class ColumnMapFieldMapping

Following copied from class: kodo.jdbc.meta.AbstractFieldMapping

See Also:

AbstractFieldMapping.addMappingInfoAttributes(java.util.Collection)

map

public boolean map()

Description copied from interface: 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 ColumnMapFieldMapping

loadProjection

public Object loadProjection(JDBCStoreManager store,
                             JDBCFetchConfiguration fetch,
                             Result res,
                             Joins joins)
                      throws SQLException

Description copied from interface: FieldMapping

Load this field value using the given result. This method will only be called if this field does not represent a FCO relation. The result will contain the columns from FieldMapping.getColumns().

loadKeyProjection

public Object loadKeyProjection(JDBCStoreManager store,
                                JDBCFetchConfiguration fetch,
                                Result res,
                                Joins joins)
                         throws SQLException

Description copied from interface: FieldMapping

Load this field's key value using the given result. This method will only be called if the key on this field does not represent a FCO relation. The result will contain the columns from FieldMapping.getKeyColumns().

Overrides:

loadKeyProjection in class AbstractFieldMapping
