Class ObservableList<T>

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

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

public class ObservableList<T>
extends java.util.ArrayList<T>
implements ObservableCollection<T>
extends java.util.ArrayList<T>
implements ObservableCollection<T>

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<T> c)` Constructs a list containing the elements of the specified collection, in the order they are returned by the collection's iterator.
