Class TransformationMapping

java.lang.Object

org.eclipse.persistence.core.mappings.CoreMapping<AttributeAccessor,AbstractSession,ContainerPolicy,ClassDescriptor,DatabaseField>

org.eclipse.persistence.mappings.DatabaseMapping

org.eclipse.persistence.mappings.foundation.AbstractTransformationMapping

org.eclipse.persistence.mappings.TransformationMapping

All Implemented Interfaces:

Serializable, Cloneable, RelationalMapping

public class TransformationMapping
extends AbstractTransformationMapping
implements RelationalMapping

Purpose: A transformation mapping is used for a specialized translation between how a value is represented in Java and its representation on the databae. Transformation mappings should only be used when other mappings are inadequate.

Since:

TOPLink/Java 1.0
