All Implemented Interfaces:

CSProcess

public class Skip
extends Guard
implements CSProcess

This is a process that immediately terminates and a Guard that is always ready.

Description

Skip is a process that starts, engages in no events, performs no computation and terminates. It can also be used as a Guard in an Alternative that is always ready.

Note: the process form is included for completeness -- it is one of the fundamental primitives of CSP.
