Abstract :
We define a predicate-transformer semantics for an object oriented language that includes specification constructs from refinement calculi. The language includes recursive classes, visibility control, dynamic binding, and recursive methods. Using the semantics, we formulate notions of refinement. Such results are a first step toward a refinement calculus
