public class ListSet<E>
extends java.util.ArrayList<E>

ListSet is an internal Vaadin class which implements a combination of a List and a Set. The main purpose of this class is to provide a list with a fast contains(Object) method. Each inserted object must by unique (as specified by AbstractList.equals(Object)). The set(int, Object) method allows duplicates because of the way Collections.sort(java.util.List) works. This class is subject to change and should not be used outside Vaadin core.
