NAME

classes/retcontinuation.pmc - Return Continuation

DESCRIPTION

RetContinuation extends Continuation.

A return continuation is like a Continuation, only its context isn't marked, because that's just some previous state of the interpreter.

Methods

void init()

Initializes the continuation.

PMC *clone

Return a new Continuation PMC with the context of SELF. Note: the returned object is not a RetContinuation and creating a real Continuation invalidates all RetContinuation all the way up the call chain that is, these can't be recycled, they get persistent until the GC gets at them.

void *invoke(void *next)

Restores the "context" by calling the superclass's invoke() and places the frame pointer in the stack frame cache.
