Class TransformationMapping

java.lang.Object
  org.eclipse.persistence.mappings.DatabaseMapping
      org.eclipse.persistence.mappings.foundation.AbstractTransformationMapping
          org.eclipse.persistence.mappings.TransformationMapping

All Implemented Interfaces:

java.io.Serializable, java.lang.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.
