public ObjectChangeSet
getChangedObject()

Implements org.eclipse.persistence.sessions.changesets.AggregateChangeRecord.getChangedObject.

ADVANCED: This method is used to return the ObjectChangeSet representing the changed Aggregate.
public Object
getOldValue()

Implements org.eclipse.persistence.sessions.changesets.AggregateChangeRecord.getOldValue, org.eclipse.persistence.sessions.changesets.ChangeRecord.getOldValue.

ADVANCED: If the owning UnitOfWork has shouldChangeRecordKeepOldValue set to true, then return the old value of the attribute represented by this ChangeRecord.
public void
mergeRecord(ChangeRecord mergeFromRecord, UnitOfWorkChangeSet mergeToChangeSet, UnitOfWorkChangeSet mergeFromChangeSet)

Implements abstract org.eclipse.persistence.internal.sessions.ChangeRecord.mergeRecord.

INTERNAL: This method will be used to merge one record into another
public void
setChangedObject(ObjectChangeSet newValue)

INTERNAL: This method is used to set the changed value or values.

public void
setOldValue(Object oldValue)

INTERNAL: Set the old value of the attribute represented by this ChangeRecord.

public void
updateReferences(UnitOfWorkChangeSet mergeToChangeSet, UnitOfWorkChangeSet mergeFromChangeSet)

Implements abstract org.eclipse.persistence.internal.sessions.ChangeRecord.updateReferences.

INTERNAL: This method will be used to update the objectsChangeSets references If this is an aggregate change set then there is no need to update the reference as the ChangeSet has no identity outside of this record Check to see if it exists here already to prevent us from creating a little extra garbage.
