- All Implemented Interfaces:
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.
This makes it useful for polling
a set of guards to test if any are ready:
include it as the last element of the guard array and
priSelect
.
Note: the process is also included for completeness – it is one of
the fundamental primitives of CSP, where it is a unit of sequential
composition and parallel interleaving.
In JCSP, it is a unit of Sequence
, Parallel
and PriParallel
.
