All Implemented Interfaces:

MappingCallbacks

public class OracleCollectionMapping
extends CollectionMapping

Oracle variant of the CollectionMapping for cases where we are serialising the field into a single column. This is necessary so we can intercept perform any necessary postInsert, postUpdate nonsense for inserting BLOBs

Method Detail

postInsert

public void postInsert(org.datanucleus.state.ObjectProvider ownerOP)

Retrieve the empty BLOB created by the insert statement and write out the current BLOB field value to the Oracle BLOB object.

Specified by:

postInsert in interface MappingCallbacks

Overrides:

postInsert in class CollectionMapping

Parameters:

ownerOP - ObjectProvider of the owner

postUpdate

public void postUpdate(org.datanucleus.state.ObjectProvider ownerOP)

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:

ownerOP - ObjectProvider of the owner
