AVABI: Automated validation for behavioral interfaces of asynchronous active objects (completed)


The Avabi-project is funded as a bilateral Norwegian-German cooperation within the PPP-programme for collaborative research support scheme (``Projektbezogener Personenaustausch''). The cooperation is funded by the


The planned duration of the project is 24 months, the funding period spans the years 2008 and 2009.

In a nutshell


A strong current trend in software is towards component-based object-oriented systems, as they promise compositional development and deployment of software. Integral part of any component-based and compositional system description is the notion of interface, and recently, so-called behavioral interface descriptions, have begun to find acceptance, where ``behavioral'' refers to properties going beyond simple static properties like availability of methods or matching parameters. In this project we develop an appropriate behavioral interface description language for Creol, an object-oriented, concurrent programming language based on active objects, which is being developed at the University of Oslo. The formal interface description is intended as the core of a component-model for Creol, and using the interface language, we will develop and apply automated validation techniques. Beyond developing appropriate interface abstractions, the project will enhance the Creol-language by facilities for testing and simulation, extending the current Creol-implementation in the rewrite-engine Maude, resp. extending previous work for Java to the Creol setting. In addition, we apply model-checking to check interface conformance, following the well-established methodology of counter-example guided abstraction refinement.
