addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener listener)

removePropertyChangeListener

public void removePropertyChangeListener(PropertyChangeListener listener)

firePropertyChange

public void firePropertyChange(String propertyName,
 Object oldValue,
 Object newValue)

Fire an event for property changed. It will be fired when

• oldValue == null
• newValue == null
• !oldValue.equals(newValue)

The property name will be put to event, but NOT used for filtering to listeners. All listeners will be called synchronously. The order is not guaranteed. As the event is immutable, the same event will be fired to all listeners.
