TransformationMapping (Oracle Fusion Middleware Java API Reference for Oracle TopLink)

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.
