      IllegalAccessException - if an illegal access occurs when invoking the method addPropertyChangeListener

    • removePropertyChangeListener

      public static void removePropertyChangeListener(PropertyChangeListener listener, Object bean) throws InvocationTargetException, NoSuchMethodException, IllegalAccessException
      Remove the given listener from the given bean using the normalized method named removePropertyChangeListener.
      Parameters:
      listener - the listener to remove
      bean - the bean on which the listener is removed
      Throws:
      InvocationTargetException - if could not invoke the method removePropertyChangeListener
