Class EditorMethodReference2

  • All Implemented Interfaces:
    IClassReferenceListener, EventListener, IGProp<GProp<?>[]>, IPropCnr, java.lang.Cloneable
    Direct Known Subclasses:
    EditorFieldActor

    public abstract class EditorMethodReference2
    extends MethodReference2
    implements IClassReferenceListener
    The Designer version the Method Reference "2" property class hold the reference to a Method that is in a Java class.

    Two variants are supported:

    1. As for classic MethodReference:
      a Java class reference "ClassReference" is held by a parent container in the tree, and this method reference is a simple name without '.' and is the method in the class.
    2. a static method reference in a class, where this name is the fully qualified class name with the method name last.

    • Constructor Detail

      • EditorMethodReference2

        public EditorMethodReference2()
        Creates a Method Reference property with no name and with a null value.

        public EditorMethodReference2​(Atom propertyAtom)

      • EditorMethodReference2

        public EditorMethodReference2​(Atom propertyAtom,
                                      java.lang.String newValue)
        Creates a Method Reference property with the specified name and value.

      • clone

        public EditorMethodReference2 clone()
        Creates a clone out of this property. The cloning is overridden by the super classes in order to handle cloning of its class variables appropriately.

        Cloning is used for "virtualization" of a property tree in the server. Client property classes will therefore throw CloneNotSupportedException.

        Once a tree has been cloned, the change-flag is reset, and the create-flag is set. All listeners are also removed! The new cloned property is an orphan, i.e. has no parent set.

        Note that the cloning process is done WITHOUT thread synchronization for performance reasons, thus no modifications should be done to the tree!

        Overrides:
        clone in class PropCnr

      • onEventSelf

        public void onEventSelf​(GEvent event)
        Event processing for Java Class Reference changed.

      • onReferenceEvent

        protected void onReferenceEvent​(ResolveReferencesEvent event)
        Called to perform reference resolving. A property should override this method if it needs to perform reference resolving and validation.

        Subclasses override this method and only subclasses extending PropCnr needs to call super.onReferenceEvent(ResolveReferenceEvent event).

        Overrides:
        onReferenceEvent in class PropCnr
        Parameters:
        event - The resolve references event.
