Method Detail

performSetPostProcessing

public void performSetPostProcessing(org.datanucleus.state.DNStateManager sm)

Description copied from class: JavaTypeMapping

Perform any INSERT/UPDATE post processing as required by constituent ColumnMappings. Default implementation does nothing.

Overrides:

performSetPostProcessing in class JavaTypeMapping

Parameters:

sm - StateManager of the object with this mapping

postInsert

public void postInsert(org.datanucleus.state.DNStateManager ownerSM)

Description copied from interface: MappingCallbacks

Method called after the insert of the object so that additional operations can be performed if necessary.

Specified by:

postInsert in interface MappingCallbacks

Overrides:

postInsert in class CollectionMapping

Parameters:

ownerSM - StateManager of the owner

postUpdate

public void postUpdate(org.datanucleus.state.DNStateManager ownerSM)

Description copied from class: CollectionMapping

Method to be called after any update of the owner class element. This method could be called in two situations

• Update a collection field of an object by replacing the collection with a new collection, so UpdateRequest is called, which calls here
• Persist a new object, and it needed to wait til the element was inserted so goes into dirty state and then flush() triggers UpdateRequest, which comes here

Specified by:

postUpdate in interface MappingCallbacks

Overrides:

postUpdate in class CollectionMapping

Parameters:

ownerSM - StateManager of the owner
