Enclosing class:

AbstractParameter

protected static class AbstractParameter.WorkArea
extends java.lang.Object
implements Scopeable

Object which manages the context local state of field assigners. It manages a deque of scopes, each of which contains zero or more OutputParameterAssigner objects. As the currently executing program's block scopes open and close, these scopes are pushed and popped from the deque.
