Class SwingPropertyChangeSupport

java.lang.Object

java.beans.PropertyChangeSupport

javax.swing.event.SwingPropertyChangeSupport

All Implemented Interfaces:

Serializable

public final class SwingPropertyChangeSupport
extends PropertyChangeSupport

This subclass of java.beans.PropertyChangeSupport is almost identical in functionality. The only difference is if constructed with SwingPropertyChangeSupport(sourceBean, true) it ensures listeners are only ever notified on the Event Dispatch Thread.

Methods declared in class Object

clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait

Modifier and Type	Method	Description
protected Object	clone()	Answers a new instance of the same class as the receiver, whose slots have been filled in with the values in the slots of the receiver.
boolean	equals(Object o)	Compares the argument to the receiver, and answers true if they represent the same object using a class specific comparison.
protected void	finalize()	Deprecated, for removal: This API element is subject to removal in a future version. May cause performance issues, deadlocks and hangs.
final Class<? extends Object>	getClass()	Answers the unique instance of java.lang.Class which represents the class of the receiver.
int	hashCode()	Answers an integer hash code for the receiver.
final void	notify()	Causes one thread which is waiting on the receiver to be made ready to run.
final void	notifyAll()	Causes all threads which are waiting on the receiver to be made ready to run.
String	toString()	Answers a string containing a concise, human-readable description of the receiver.
final void	wait()	Causes the thread which sent this message to be made not ready to run pending some change in the receiver (as indicated by notify or notifyAll).
final void	wait(long time)	Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by notify or notifyAll) or the expiration of the timeout.
final void	wait(long time, int frac)	Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by notify or notifyAll) or the expiration of the timeout.

Constructor Details

SwingPropertyChangeSupport

public SwingPropertyChangeSupport(Object sourceBean)

Constructs a SwingPropertyChangeSupport object.

Parameters:

sourceBean - The bean to be given as the source for any events.

Throws:

NullPointerException - if sourceBean is null

SwingPropertyChangeSupport

public SwingPropertyChangeSupport(Object sourceBean,
 boolean notifyOnEDT)

Constructs a SwingPropertyChangeSupport object.

Parameters:

sourceBean - the bean to be given as the source for any events

notifyOnEDT - whether to notify listeners on the Event Dispatch Thread only

Throws:

NullPointerException - if sourceBean is null

Since:

1.6

Method Details

firePropertyChange

public void firePropertyChange(PropertyChangeEvent evt)

Fires a property change event to listeners that have been registered to track updates of all properties or a property with the specified name.

No event is fired if the given event's old and new values are equal and non-null.

If isNotifyOnEDT() is true and called off the Event Dispatch Thread this implementation uses SwingUtilities.invokeLater to send out the notification on the Event Dispatch Thread. This ensures listeners are only ever notified on the Event Dispatch Thread.

Overrides:

firePropertyChange in class PropertyChangeSupport

Parameters:

evt - the PropertyChangeEvent to be fired

Throws:

NullPointerException - if evt is null

Since:

1.6

isNotifyOnEDT

public boolean isNotifyOnEDT()

Returns notifyOnEDT property.

Returns:

notifyOnEDT property

Since:

1.6
