The Design of GCCL: a Generalized Common Contract Language


Following its inception in Eiffel by Meyer and its diffusion to other environments (e.g., the standardisation of OCL as part of UML), Design by Contract now faces a major challenge in component-based software engineerin- g (CBSE). Compositional reasoning about system properties from component ones has been recently asserted by the SEI as the "key technical challenge" of CBSE, and contracts as a "key technical concept to support this vision". To live up to these expectations, DbC must tackle extra-functional properties of components and support Klein's "architectural-based attribute reasoning." Besides adopting the necessary new concepts, a good contract language must provide for abstraction, application, composition and scoping mechanisms in such a way to be used from modeling in UML to programming in standard languages (as seamless extensions to Java, C#, C++, Eiffel, and so on) through execution on traditional operating systems with minimal middleware additions. This paper examines conceptual foundations and design decisions to propose GCCL, a novel open generalized common contract language. GCCL is meant to be compatible with existing DbC (sub)languages, and especially OCL.
