public final class WeakListChangeListener<E> extends Object implements ListChangeListener<E>, WeakListener
AWeakListChangeListener

are created by passing in the originalListChangeListener
. TheWeakListChangeListener
should then be registered to listen for changes of the observed object.Note: You have to keep a reference to the
ListChangeListener
