....of classes is understood as parametric polymorphism. With polymorphism characterized by substitution (see Sect. 3.3) generic classes may be used in different situations 26 uniformly by actualizing their formal parameter. In correspondence with horizontal and vertical implementation [19], substitution may be called vertical in the context of inheritance, and horizontal in the context of parametrization. Parametrical polymorphism allows for parallel development of generic classes and their parameters, and is thus orthogonal to inheritance. A detailed discussion can be found, for ....

....architectural specifications. 1 Introduction There has been a great deal of work in the algebraic specification tradition on formalizing the rather intuitive and appealing idea of program development by stepwise refinement, including [EKMP82,Gan83,GM82,Sch87,ST88b] for a recent survey, see [EK99] There are many issues that make this a di#cult problem, and some of them are rather subtle, one example being the relationship between specification structure and program structure. There are di#cult interactions and tradeo#s, an obvious one being between the expressive power of a ....
