Class ObservableList

java.lang.Object
  java.util.AbstractCollection<E>
      java.util.AbstractList<E>
          java.util.ArrayList
              nl.knowledgeplaza.util.collection.ObservableList

All Implemented Interfaces:: java.io.Serializable, java.lang.Cloneable, java.lang.Iterable, java.util.Collection, java.util.List, java.util.RandomAccess, ObservableCollection

public class ObservableList
extends java.util.ArrayList
implements ObservableCollection
extends java.util.ArrayList
implements ObservableCollection

The ObservableList subclasses the ArrayList and overrides all the functions that change the internally stored collection. In the overridden function, it simply calls the super class's function and fires a CollectionEvent to let observers know the collection has changed. TOEU 2007-01-29: this implementation sucks! It does not update all changes, just that there has been a change. Made some improvements.

Constructor Summary
`ObservableList()` Constructs an empty list with an initial capacity of ten.
`ObservableList(java.util.Collection c)` Constructs a list containing the elements of the specified collection, in the order they are returned by the collection's iterator.
`ObservableList(int initialCapacity)` Constructs an empty list with the specified initial capacity.

Method Summary
`void`	`add(int index, java.lang.Object element)` Calls the super class's corresponding method and fires a CollectionEvent.
`boolean`	`add(java.lang.Object o)` Calls the super class's corresponding method and fires a CollectionEvent.
`boolean`	`addAll(java.util.Collection c)` Calls the super class's corresponding method and fires a CollectionEvent.
`boolean`	`addAll(int index, java.util.Collection c)` Calls the super class's corresponding method and fires a CollectionEvent.
`void`	`addCollectionListener(CollectionListener l)` Adds a listener to this collection.
`void`	`clear()` Calls the super class's corresponding method and fires a CollectionEvent.
`protected void`	`fireCollectionEvent(CollectionEvent e)` Fires a CollectionEvent to all listeners.
`java.lang.Object`	`getObservedCollection()` To access the collection that is being observed.
`java.lang.Object`	`remove(int index)` Calls the super class's corresponding method and fires a CollectionEvent.
`boolean`	`remove(java.lang.Object o)` Calls the super class's corresponding method and fires a CollectionEvent.
`boolean`	`removeAll(java.util.Collection c)` Calls the super class's corresponding method and fires a CollectionEvent.
`void`	`removeCollectionListener(CollectionListener l)` Removes the listener from this collection.
`boolean`	`retainAll(java.util.Collection c)` Calls the super class's corresponding method and fires a CollectionEvent.
`java.lang.Object`	`set(int index, java.lang.Object element)` Calls the super class's corresponding method and fires a CollectionEvent.
