All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

Direct Known Subclasses:

EISTransformationMapping, TransformationMapping, XMLTransformationMapping

public abstract class AbstractTransformationMapping
extends DatabaseMapping

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.
