- 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

initialize
public void initialize(AbstractTransformationMapping mapping)
Description copied from interface:FieldTransformerInitialize this transformer. Only required if the user needs some special information from the mapping in order to do the transformation- Specified by:
initializein interfaceFieldTransformer- Parameters:
mapping- - the mapping this transformer is associated with.
-
getFieldType
public java.lang.Class getFieldType()
Return the Java class type of the field value. This uses the method return type.
-
buildFieldValue
public java.lang.Object buildFieldValue(java.lang.Object object, java.lang.String fieldName, Session session)- Specified by:
buildFieldValuein interfaceCoreFieldTransformer<Session>- Specified by:
buildFieldValuein interfaceFieldTransformer- Parameters:
object- - an instance of the domain class which contains the attributefieldName- - 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
