All Implemented Interfaces:
Serializable, 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.
