public class BasicPropertyEventSource
extends Object
implements PropertyEventSource, JavaBean, Serializable, Copyable

Base implementation of PropertyEventSource. In order to provide property change notification classes may either simply extend this class (use by inheritance) or create a standalone instance and forward methods to it (use by composition) with the event source set to be the containing instance.

NOTE: in the use by composition case, it is the client clone () method's responsibility to update the event source correctly, eg via a call to setPropertyChangeSource(java.lang.Object).

This class also implements the JavaBean marker interface.

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.
