                                                                               org.eclipse.persistence.internal.sessions.AbstractSession session)

INTERNAL: Build and return the change record that results from comparing the two collection attributes.

compareObjects

public boolean compareObjects(java.lang.Object object1,
                              java.lang.Object object2,
                              org.eclipse.persistence.internal.sessions.AbstractSession session)

INTERNAL: Compare the attributes belonging to this mapping for the objects.

getDatabaseMapping

public DatabaseMapping getDatabaseMapping()

INTERNAL: Return the mapping, casted a bit more generally.

getMapping

public EISOneToManyMapping getMapping()

INTERNAL: Return the mapping.

mergeChangesIntoObject

public void mergeChangesIntoObject(java.lang.Object target,
                                   org.eclipse.persistence.internal.sessions.ChangeRecord changeRecord,
                                   java.lang.Object source,
                                   org.eclipse.persistence.internal.sessions.MergeManager mergeManager,
                                   org.eclipse.persistence.internal.sessions.AbstractSession targetSession)

INTERNAL: Merge changes from the source to the target object.

mergeIntoObject

public void mergeIntoObject(java.lang.Object target,
                            boolean isTargetUnInitialized,
                            java.lang.Object source,
                            org.eclipse.persistence.internal.sessions.MergeManager mergeManager,
                            org.eclipse.persistence.internal.sessions.AbstractSession targetSession)

INTERNAL: Merge changes from the source to the target object. Simply replace the entire target collection.

simpleAddToCollectionChangeRecord

public void simpleAddToCollectionChangeRecord(java.lang.Object referenceKey,
                                              java.lang.Object changeSetToAdd,
