Stack

Stack		Description
Stack(In)		a wrapper
Stack(Out)		the core object

On the stack, a wrapped object of, for example, class CX_DESCRIPTIVE_REF, CX_OVERWRITING_REF or CX_COND_WRAPPER is expected and the wrapped object is returned. If the wrapped object is in turn a wrapper object, Core returns the object wrapped in it, and so on.

If the wrapper is empty or if (for a conditioned wrapper) no object matches the plugspace, NULL is returned.
