Examples of TransformationMapping

nexj.core.meta.integration.TransformationMapping
Transformation mapping for translating between multiple source values and one destination value.
org.eclipse.persistence.internal.oxm.mappings.TransformationMapping
org.eclipse.persistence.mappings.TransformationMapping

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. @author Sati @since TOPLink/Java 1.0
