Class CodeComponent<D extends CodeDelegate>

  • Type Parameters:
    D - wrapped delegate type
    All Implemented Interfaces:
    Component
    Direct Known Subclasses:
    CodeContainer, CodeRoot

    public class CodeComponent<D extends CodeDelegate>
    extends Object
    implements Component
    A CodeComponent is a Component instance that is rewritable at runtime. The CodeComponent itself remains constant, but passes most responsibility to a CodeContext wrapping a CodeDelegate (user code). This component handles switching from one context to the next. A CodeComponent cannot be created directly - see CodeFactory.

      • getParent

        public final Container getParent()
        Description copied from interface: Component
        Return the Container that is the immediate parent of this Component, or null if this Component is not currently contained within a Component hierarchy.
        Specified by:
        getParent in interface Component

        Container
      • parentNotify

        public void parentNotify​(Container parent)
                          throws VetoException
        Description copied from interface: Component
        Notify the Component that it has been added to the supplied Container, or removed from its parent if the supplied argument is null. The Component may throw a VetoException if it should not be added to the Container provided. It should also throw this exception if a parent is already set.
        Specified by:
        parentNotify in interface Component
        Throws:
        VetoException
      • hierarchyChanged

        public void hierarchyChanged()
        Description copied from interface: Component
