  • Method Details

    • addPropertyChangeListener

      void addPropertyChangeListener​(java.beans.PropertyChangeListener listener)
      Add a PropertyChangeListener to the listener list. The listener is registered for all properties. The same listener object may be added more than once, and will be called as many times as it is added. If listener is null, no exception is thrown and no action is taken.
      Parameters:
      listener - The PropertyChangeListener to be added

    • removePropertyChangeListener

      void removePropertyChangeListener​(java.beans.PropertyChangeListener listener)
      Remove a PropertyChangeListener from the listener list. This removes a PropertyChangeListener that was registered for all properties. If listener was added more than once to the same event source, 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 PropertyChangeListener to be removed

    • getPropertyChangeListeners

      java.beans.PropertyChangeListener[] getPropertyChangeListeners()
      Returns an array of all the listeners that were added to the PropertyChangeSupport object with addPropertyChangeListener().

      If some listeners have been added with a named property, then the returned array will be a mixture of PropertyChangeListeners and PropertyChangeListenerProxys. If the calling method is interested in distinguishing the listeners then it must test each element to see if it's a PropertyChangeListenerProxy, perform the cast, and examine the parameter. 

       PropertyChangeListener[] listeners = bean.getPropertyChangeListeners();
 for (int i = 0; i < listeners.length; i++) {
     if (listeners[i] instanceof PropertyChangeListenerProxy) {
     PropertyChangeListenerProxy proxy =
                    (PropertyChangeListenerProxy)listeners[i];
     if (proxy.getPropertyName().equals("foo")) {
       // proxy is a PropertyChangeListener which was associated
       // with the property named "foo"
     }
   }
 }
      Returns:
      all of the PropertyChangeListeners added or an empty array if no listeners have been added

    • addPropertyChangeListener

      void addPropertyChangeListener​(java.lang.String propertyName, java.beans.PropertyChangeListener listener)
      Add a PropertyChangeListener for a specific property. The listener will be invoked only when a call on firePropertyChange names that specific property. The same listener object may be added more than once. For each property, the listener will be invoked the number of times it was added for that property. If propertyName or listener is null, no exception is thrown and no action is taken.
      Parameters:
      propertyName - The name of the property to listen on.
      listener - The PropertyChangeListener to be added

    • removePropertyChangeListener

      void removePropertyChangeListener​(java.lang.String propertyName, java.beans.PropertyChangeListener listener)
      Remove a PropertyChangeListener for a specific property. If listener was added more than once to the same event source for the specified property, it will be notified one less time after being removed. If propertyName is null, no exception is thrown and no action is taken. If listener is null, or was never added for the specified property, no exception is thrown and no action is taken.
      Parameters:
      propertyName - The name of the property that was listened on.
      listener - The PropertyChangeListener to be removed

    • getPropertyChangeListeners

      java.beans.PropertyChangeListener[] getPropertyChangeListeners​(java.lang.String propertyName)
      Returns an array of all the listeners which have been associated with the named property.
      Parameters:
      propertyName - The name of the property being listened to
      Returns:
      all of the PropertyChangeListeners associated with the named property. If no such listeners have been added, or if propertyName is null, an empty array is returned.

    • firePropertyChanged

      void firePropertyChanged​(java.lang.String propertyName, java.lang.Object oldValue, java.lang.Object newValue)
