Class ObjectBinding

  • All Implemented Interfaces:
    IComponent, IContextObj, ILinkable, ITypeBinding

    public class ObjectBinding
    extends PassThroughComponent
    implements IComponent, IContextObj
    Binding modifiers that apply to a class reference. This adds the methods used for handling binding operations to the object class (or a helper class), then generates calls to the added methods as this binding definition is used.
