Class MethodBasedFieldTransformer

java.lang.Object
oracle.toplink.mappings.transformers.MethodBasedFieldTransformer

All Implemented Interfaces:

java.io.Serializable, FieldTransformer

public class MethodBasedFieldTransformer

extends java.lang.Object

implements FieldTransformer

Since:

10 This class is used to preserve the old method of doing Field Transformations on a transformation mapping. It is used internally when the older API is used on a TransformationMapping, and handles doing invocations on the user's domain class
