Abstract Interface Behavior of Object-Oriented Languages with Monitors

  • Erika Ábrahám

We characterize the observable behavior of multi-threaded, object-oriented components with re-entrant monitors. We show that a compositional approach leads to observable uncertainty wrt. monitor operations at the interface which we capture by may- and must-approximations for potential, resp. necessary lock ownership. The concepts are formalized in an object calculus. We show the soundness of the abstractions.
