Coalgebra Semantics for Hidden Algebra: Parameterised Objects and Inheritance
Cirstea, Corina (1998) Coalgebra Semantics for Hidden Algebra: Parameterised Objects and Inheritance. In, 12th International Workshop on Algebraic Development Techniques Springer, 174-189.
The theory of hidden algebras combines standard algebraic techniques with coalgebraic techniques to provide a semantic foundation for the object paradigm. This paper focuses on the coalgebraic aspect of hidden algebra, concerned with signatures of destructors at the syntactic level and with finality and cofree constructions at the semantic level. Our main result shows the existence of cofree constructions induced by maps between coalgebraic hidden specifications. Their use in giving a semantics to parameterised objects and inheritance is then illustrated. The cofreeness result for hidden algebra is generalised to abstract coalgebra and a universal construction for building object systems over existing subsystems is obtained. Finally, existence of final/cofree constructions for arbitrary hidden specifications is discussed.
