Class ObservableSortedSet

java.lang.Object
  java.util.AbstractCollection<E>
      java.util.AbstractSet<E>
          java.util.TreeSet
              nl.knowledgeplaza.util.collection.ObservableSortedSet

All Implemented Interfaces:: Serializable, Cloneable, Iterable, Collection, Set, SortedSet, ObservableCollection

public class ObservableSortedSet
extends TreeSet
implements ObservableCollection
extends TreeSet
implements ObservableCollection

The ObservableSortedSet subclasses the TreeSet 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.

Field Summary
`protected ArrayList`	`listeners` the observers of this collection

Constructor Summary
`ObservableSortedSet()` Constructs a new, empty set, sorted according to the elements' natural order.
`ObservableSortedSet(Collection c)` Constructs a new set containing the elements in the specified collection, sorted according to the elements' natural order.
`ObservableSortedSet(Comparator c)` Constructs a new, empty set, sorted according to the specified comparator.
`ObservableSortedSet(SortedSet s)` Constructs a new set containing the same elements as the specified sorted set, sorted according to the same ordering.

Method Summary
`boolean`	`add(Object o)` Calls the super class's corresponding method and fires a CollectionEvent.
`boolean`	`addAll(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.
`Object`	`getObservedCollection()` To access the collection that is being observed.
`boolean`	`remove(Object o)` Calls the super class's corresponding method and fires a CollectionEvent.
`boolean`	`removeAll(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(Collection c)` Calls the super class's corresponding method and fires a CollectionEvent.

Constructor Detail

ObservableSortedSet

public ObservableSortedSet()

Constructs a new, empty set, sorted according to the elements' natural order.

ObservableSortedSet

public ObservableSortedSet(Comparator c)

Constructs a new, empty set, sorted according to the specified comparator. All elements inserted into the set must be mutually comparable by the specified comparator: comparator.compare(e1, e2) must not throw a ClassCastException for any elements e1 and e2 in the set. If the user attempts to add an element to the set that violates this constraint, the add(Object) call will throw a ClassCastException.

Parameters:: c - the comparator that will be used to sort this set. A null value indicates that the elements' natural ordering should be used.

ObservableSortedSet

public ObservableSortedSet(Collection c)

Constructs a new set containing the elements in the specified collection, sorted according to the elements' natural order. All keys inserted into the set must implement the Comparable interface. Furthermore, all such keys must be mutually comparable: k1.compareTo(k2) must not throw a ClassCastException for any elements k1 and k2 in the set.

Parameters:: c - The elements that will comprise the new set.

ObservableSortedSet

public ObservableSortedSet(SortedSet s)

Constructs a new set containing the same elements as the specified sorted set, sorted according to the same ordering.

Parameters:: s - sorted set whose elements will comprise the new set.
