initialize
public void initialize(AbstractTransformationMapping mapping)
Description copied from interface:FieldTransformer
Initialize this transformer. Only required if the user needs some special information from the mapping in order to do the transformation- Specified by:
initialize
in interfaceFieldTransformer
- Parameters:
mapping
- - the mapping this transformer is associated with.
-
getFieldType
public Class<?> getFieldType()
Return the Java class type of the field value. This uses the method return type.

buildFieldValue
public Object buildFieldValue(Object object, String fieldName, Session session)
- Specified by:
buildFieldValue
in interfaceCoreFieldTransformer<Session>
- Specified by:
buildFieldValue
in 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
