int[] getAddIndexes()

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

getAdds

java.util.Vector getAdds()

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

These two indexes can be equal.

getMoves

java.util.Vector getMoves()

ADVANCED: Return the entries for all the elements that were simply shuffled within the collection. The contents of this collection is determined by the mapping that populated it

getNewCollection

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

getRemoveIndexes

int[] getRemoveIndexes()

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

getRemoves

java.util.Vector getRemoves()
