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.

emptyClone

protected BasicMonitoredCollection emptyClone()
                                       throws CloneNotSupportedException

Make an empty clone of this collection (ie a copy with none of the original elements).

Throws:

CloneNotSupportedException

removeCollectionListener

public void removeCollectionListener(CollectionListener l)

Specified by:

removeCollectionListener in interface MonitoredCollection

addCollectionListener

public void addCollectionListener(CollectionListener l)

Specified by:
