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

                                        java.lang.String fieldName,
                                        Session session)

Specified by:

buildFieldValue in interface FieldTransformer

Parameters:

object - - an instance of the domain class which contains the attribute

fieldName - - the name of the field being transformed. Used if the user wants to use this transformer for multiple fields.

session - - the current session

Returns:

- The value to be written for the field associated with this transformer
