@API(status=EXPERIMENTAL) public interface Mutable
An interface that describes the capability of mutate status and of supporting listeners. Both old-style PropertyChangeListener and a new experimental MutableListeners are supported. The three different methods addListener1(MutableListener1), addListener2(MutableListener2) and addListener(MutableListener) allow shorter syntaxes when only one or two parameters of the callback are needed, that is: 
 
 mutable.addMutableListener1(newValue -> consumer1.accept(newValue));
 mutable.addMutableListener2((oldValue, newValue) -> consumer2.accept(oldValue, newValue));
 mutable.addMutableListener((source, oldValue, newValue) -> consumer3.accept(source, oldValue, newValue));

      Parameters:
      propertyName - the name of the property

      true if the property is bound

    • addListener

      <T> void addListener(@Nonnull MutableListener<T> listener)
      Registers a MutableListener.
      Parameters:
      listener - the listener
