Java implementation platform for the integrated state- and event-based specification in PROB.

PROB is an animation and model checking tool, which supports integrated event- and state-based specifications combining B and CSP. We present an initial strategy for implementing the combined specification model as a concurrent Java program. Our Java implementation for the combined B and CSP model uses a similar approach to that of JCSP. The restricted operational semantics for the integrated B and CSP model in PROB is defined. Then a new Java package, JCSProB, is developed for implementing the semantics. The new package supports external choice with multi-way synchronization, and introduces an improved multi-threading implementation from JCSP. Copyright © 2009 John Wiley & Sons, Ltd.
