Method Detail

getAddIndexes

public int[] getAddIndexes()

ADVANCED: Return the indexes into the new collection of the elements that were added.

getMoveIndexes

public int[][] getMoveIndexes()

ADVANCED: Return the indexes of the elements that were simply moved. Each element in the outer array is another two-element array where the first entry [0] is the index of the object in the old collection and the second entry [1] is the index of the object in the new collection.

getNewCollection

public java.util.Vector getNewCollection()

ADVANCED: Return the entries for all the elements in the new collection. The contents of this collection is determined by the mapping that populated it:

SDKAggregateCollectionMapping will store ObjectChangeSets
SDKDirectCollectionMapping will store the direct elements themselves
SDKObjectCollectionMapping will store the foreign keys

getRemoveIndexes

public int[] getRemoveIndexes()

ADVANCED: Return the indexes into the old collection of the elements that were removed.

hasChanges

public boolean hasChanges()

ADVANCED: Return whether any changes have been recorded with the change record.
