Method Summary

Modifier and Type	Method	Description
List<ObjectChangeSet>	getChangedValues()	ADVANCED: Return the values representing the changed AggregateCollection.
void	mergeRecord(ChangeRecord mergeFromRecord, UnitOfWorkChangeSet mergeToChangeSet, UnitOfWorkChangeSet mergeFromChangeSet)	INTERNAL: This method will be used to merge one record into another
void	setChangedValues(List<ObjectChangeSet> newValues)	INTERNAL: Set the changed values.
void	updateReferences(UnitOfWorkChangeSet mergeToChangeSet, UnitOfWorkChangeSet mergeFromChangeSet)	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.
