Examples of java.beans.PropertyChangeSupport.firePropertyChange()

java.beans.PropertyChangeSupport.firePropertyChange()
Report a bound property update to any registered listeners. No event is fired if old and new are equal and non-null.
This is merely a convenience wrapper around the more general firePropertyChange method that takes {@code PropertyChangeEvent} value. @param propertyName The programmatic name of the propertythat was changed. @param oldValue The old value of the property. @param newValue The new value of the property.

                target, "long", "source.long");
        support.addPropertyChangeListener((PropertyChangeListener) proxy);
        PropertyChangeEvent event = new PropertyChangeEvent(fish, "name", "1",
                "5");
        support.firePropertyChange(event);
        assertEquals("long:1000", target.getActionRecord());
