public class ListenerArrayList<E>
extends ArrayList<E>

Array list extended to fire a property event whenever its data gets modified. The logic of events is as follows:

• Property name is always the method name (one of "add", "addAll", "set", "remove" or "clear").
• When one or more values have been added through add(java.lang.Object), add(int, java.lang.Object), addAll(java.util.Collection) or addAll(int, java.util.Collection), the old value in the event is null and the new value contains the value (or a collection of values).
• When an existing value is changed through set(int, java.lang.Object), the old/new values in the event correspond to the old/new values in the list.
• When one or more values have been removed through remove(java.lang.Object), remove(int), ArrayList.removeAll(java.util.Collection) or clear(), the old value in the event contains the removed value (or a collection of values) and the new value is null.
