org.eclipse.persistence.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
