This class is not serializable. since:    7.8 author:    Andrei Badea Field Summary final  List<ChangeListener> listeners      Constructor Summary public   ChangeSupport(Object source)      Method Summary public  void addChangeListener(ChangeListener listener)      Adds a ChangeListener to the listener list. public  void fireChange()      Fires a change event to all registered listeners. public  boolean hasListeners()      Checks if there are any listeners registered to thisChangeSupport. public  void removeChangeListener(ChangeListener listener)      Removes a ChangeListener from the listener list. Field Detail listeners final List<ChangeListener> listeners(Code) Constructor Detail ChangeSupport public ChangeSupport(Object source)(Code) Creates a new ChangeSupport Parameters:   source - the instance to be given as the source for events. Method Detail addChangeListener public void addChangeListener(ChangeListener listener)(Code) Adds a ChangeListener to the listener list.

Parameters:   listener - the ChangeListener to be added. fireChange public void fireChange()(Code) Fires a change event to all registered listeners. hasListeners public boolean hasListeners()(Code) Checks if there are any listeners registered to thisChangeSupport. true if there are one or more listeners for the given property,false otherwise. removeChangeListener public void removeChangeListener(ChangeListener listener)(Code) Removes a ChangeListener from the listener list. If listener was added more than once, it will be notified one less time after being removed. If listener is null, or was never added, no exception is thrown and no action is taken. Parameters:   listener - the ChangeListener to be removed.
