Class CompositeList

java.lang.Object
  java.util.AbstractCollection<E>
      java.util.AbstractList
          dsto.dfc.collections.CompositeList

All Implemented Interfaces:

CollectionListener, MonitoredCollection, MonitoredList, Copyable, Disposable, Cloneable, Iterable, Collection, EventListener, List

public class CompositeList
extends AbstractList
implements MonitoredList, CollectionListener, Disposable, Copyable

A virtual list composed of a series of sub-List's laid end to end. Tracks change events on any MonitoredList that is used as a sublist and re-fires the appropriate event.

NOTE: Any sub-list's that may change size after being added must implement MonitoredList or else this class will become out of sync.

Method Detail

clone

public Object clone()
             throws CloneNotSupportedException

Description copied from interface: Copyable

Create a completely separate copy of this object and any mutable objects owned by the object.

NOTE: subclasses should not remove the CloneNotSupportedException throws clause if they themselves support subclassing: removing the CloneNotSupportedException declaration stops subclasses from indicating that a clone was not possible.

Specified by:

clone in interface Copyable

Overrides:

clone in class Object

Throws:

CloneNotSupportedException - if the clone failed or is not possible.

dispose

public void dispose()

Description copied from interface: Disposable

Dispose of the object (unregister listeners, close open resources etc). It should be safe to call this method more than once. Note for beans that support client event listeners: if there are listeners registered when this is called, this method should do nothing.

Specified by:

dispose in interface Disposable

addList

public void addList(List list)

addList

public void addList(List list,
                    int index)

removeList

public void removeList(int index)

indexOfList

public int indexOfList(List list)

absoluteIndex

public int absoluteIndex(List list,
                         int index)

get

public Object get(int index)

Specified by:

get in interface List

Specified by:

size

public int size()

Specified by:

size in interface Collection

Specified by:

addCollectionListener

public void addCollectionListener(CollectionListener l)

Specified by:

removeCollectionListener

public void removeCollectionListener(CollectionListener l)

Specified by:

removeCollectionListener in interface MonitoredCollection

elementsAdded

public void elementsAdded(CollectionEvent e)

Specified by:
