Title: Types that Reflect Changes of Object Usability

Author:

Subject: Franz Puntigam Types that Reflect Changes of Object Usability

Description: . Strong, static typing is useful because it can improve the readability, reliability and optimizability of programs. The usability of an object may change over time. However, conventional type systems for object-oriented languages presume that objects are always used in the same way. In this paper an extension of Ada's type concept is presented: Possible changes of object usabilities can be specified as part of type declarations for passive and active objects. This extension is compatible with inheritance and supports static type checking. 1 Introduction Statically typed programming languages associate each expression in a program with a type statically derivable from the program. Strongly typed languages ensure that type errors cannot occur at run time [2]. Most programming languages used in practice are (at least in part) statically and strongly typed because static, strong typing can increase the readability and reliability of programs and supports optimizations. In object-oriente...
