All known Subclasses: org.jpox.store.mapping.ObjectMapping, org.jpox.store.mapping.InterfaceMapping,
| ReferenceMapping | | abstract public class ReferenceMapping extends MultiMapping implements MappingCallbacks(Code) | | Mapping for a reference type.
This can be used for things like interfaces, or Object which are simply a reference to
some specific (PersistenceCapable) class. All fields of this type have a list of
possible "implementations" of the reference type. A column is created for each possible
implementation of the reference as a FK to the implementation table.

| Method Summary | |
| protected void | createColumns(DatastoreContainerObject datastoreContainer, AbstractMemberMetaData fmd, ClassLoaderResolver clr)
Convenience method to create a column for each implementation type of this reference. | | public Class | getJavaType()
| | public Object | getSampleValue(ClassLoaderResolver clr)
| | public void | initialize(DatastoreAdapter dba, AbstractMemberMetaData fmd, DatastoreContainerObject container, ClassLoaderResolver clr)
Initialize this JavaTypeMapping with the given DatastoreAdapter for
the given FieldMetaData. | | public ScalarExpression | newLiteral(QueryExpression qs, Object value)
| | public ScalarExpression | newScalarExpression(QueryExpression qs, LogicSetExpression te)
| | public void | postFetch(StateManager sm)
Method executed just after a fetch of the owning object, allowing any necessary action
to this field and the object stored in it. | | public void | postInsert(StateManager sm)
Method executed just after the insert of the owning object, allowing any necessary action
to this field and the object stored in it. | | public void | postUpdate(StateManager sm)
Method executed just afer any update of the owning object, allowing any necessary action
to this field and the object stored in it. | | public void | preDelete(StateManager sm)
Method executed just before the owning object is deleted, allowing tidying up of any
relation information. |

| postFetch | | public void postFetch(StateManager sm)(Code) | | Method executed just after a fetch of the owning object, allowing any necessary action
to this field and the object stored in it.
Parameters:
sm - StateManager for the owner. |
| postInsert | | public void postInsert(StateManager sm)(Code) | | Method executed just after the insert of the owning object, allowing any necessary action
to this field and the object stored in it.

to this field and the object stored in it.
Parameters:
sm - StateManager for the owner |
| preDelete | | public void preDelete(StateManager sm)(Code) | | Method executed just before the owning object is deleted, allowing tidying up of any
relation information.
Parameters:
sm - StateManager for the owner |
