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 aCodeContext
wrapping aCodeDelegate
(user code). This component handles switching from one context to the next. A CodeComponent cannot be created directly - seeCodeFactory
