Constructor Summary

Method Summary
`void`	`clearMapping()` Clear mapping information, including strategy.
`void`	`copyMappingInfo(ValueMapping vm)` Copy mapping info from the given instance to this one.
`ColumnIO`	`getColumnIO()` I/O information on the foreign key, or columns if this value doesn't have a key.
`Column[]`	`getColumns()` The columns that hold the data for this value.
`ClassMapping`	`getDeclaredTypeMapping()` Convenience method to perform cast from `ValueMetaData.getDeclaredTypeMetaData()`.
`ClassMapping`	`getEmbeddedMapping()` Convenience method to perform cast from `ValueMetaData.getEmbeddedMetaData()`.
`FieldMapping`	`getFieldMapping()` Convenience method to perform cast from `ValueMetaData.getFieldMetaData()`.
`ForeignKey`	`getForeignKey()` If this value joins to another record, the foreign key.
`ForeignKey`	`getForeignKey(ClassMapping target)` Return an equivalent of this value's foreign key, but joining to the given target, which may be an unjoined subclass of this value's related type.
`ValueHandler`	`getHandler()` The handler used for this value, or null if none.
`ClassMapping[]`	`getIndependentTypeMappings()` Return all independently-mapped joinable types for this value, depending on whether this value is polymorphic and how the related type is mapped.
`int`	`getJoinDirection()` The join direction.
`MappingRepository`	`getMappingRepository()` Convenience method to perform cast from `MetaDataContext.getRepository()`.
`int`	`getPolymorphic()` The degree to which this relation is polymorphic.
`int`	`getSelectSubclasses()` Return the `org.apache.openjpa.sql.Select` subclasses constant for loading this relation, based on how the related type is mapped, whether this relation is polymorphic, and whether it is configured to use class criteria.
`ClassMapping`	`getTypeMapping()` Convenience method to perform cast from `ValueMetaData.getTypeMetaData()`.
`boolean`	`getUseClassCriteria()` Whether to use class criteria when joining to related type.
`Index`	`getValueIndex()` Index on this value's columns, or null if none.
`ValueMappingInfo`	`getValueInfo()` Raw mapping data.
`FieldMapping`	`getValueMappedByMapping()` Convenience method to perform cast from `ValueMetaData.getValueMappedByMetaData()`.
`Unique`	`getValueUnique()` Unique constraint on this value's columns, or null if none.
`void`	`mapConstraints(String name, boolean adapt)` Map indexes and constraints for this value, using the current `ValueMappingInfo`.
`void`	`refSchemaComponents()` Increase the reference count on used schema components.
`boolean`	`resolve(int mode)` Resolve and validate metadata.
`void`	`setColumnIO(ColumnIO io)` I/O information on the foreign key, or columns if this value doesn't have a key.
`void`	`setColumns(Column[] cols)` The columns that hold the data for this value.
`void`	`setForeignKey(ForeignKey fk)` If this value joins to another record, the foreign key.
`void`	`setForeignKey(Row row, OpenJPAStateManager rel)` Sets this value's foreign key to the given related object.
`void`	`setHandler(ValueHandler handler)` The handler used for this value, or null if none.
`void`	`setJoinDirection(int direction)` The join direction.
`void`	`setPolymorphic(int poly)` The degree to which this relation is polymorphic.
`void`	`setUseClassCriteria(boolean criteria)` Whether to use class criteria when joining to related type.
`void`	`setValueIndex(Index idx)` Index on this value's columns, or null if none.
`void`	`setValueUnique(Unique unq)` Unique constraint on this value's columns, or null if none.
`void`	`syncMappingInfo()` Update `MappingInfo` with our current mapping information.
`void`	`whereForeignKey(Row row, OpenJPAStateManager rel)` Sets this value's foreign key to the given related object.
