Constructor Detail

PCObjectCollectionFieldMapping

public PCObjectCollectionFieldMapping(FieldMetaData meta)

Constructor. Supply underlying metadata.

Method Detail

getDataStoreTypeCode

protected int getDataStoreTypeCode()

Description copied from class: ColumnCollectionFieldMapping

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

Overrides:

getDataStoreTypeCode in class ColumnCollectionFieldMapping

getDataStoreValue

public Object getDataStoreValue(Object val)

Description copied from class: 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 FieldMapping

loadProjection

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

Description copied from class: 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().

Overrides:

loadProjection in class FieldMapping

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 interface: 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. This method must validate the given mapping information using the SchemaGroup.findTable(kodo.jdbc.schema.Table) 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 validation 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 ColumnCollectionFieldMapping

Following copied from interface: kodo.jdbc.meta.Mapping

Throws:

MappingInfoNotFoundException - if the given info is invalid

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 ColumnCollectionFieldMapping
