Abstract
A relation-sorted (algebraic) specification SPEC consists of a signature, a set of equations and an arbitrary relation ⊳ on the sorts. If s⊳s' for two sorts s,s', then an operator ⊳:As → As, is assumed in every relation-sorted SPEC-algebra A.
We study the parameterization and parameter passing for relation-sorted specifications. While the parameterization in this case turns out to be a simple extension of that for many-sorted specifications, a notion of coordinate parameter passing is introduced for the parameter passing, which covers an extension of the relation ⊳ among the new generated sorts of several value specifications of one arbitrary parameterized specification. We also discuss the semantics for coordinate parameter passing.
The results obtained are specialized to order-sorted specification, since our notion of specification is more general than that of order-sorted specification.
The research has been partially supported by the Commission of the European Communities under the ESPRIT Programme in the PROSPECTRA Project, ref #390
