The virtual method is a useful concept in polymorphic behavior of object-oriented programs. By making a method virtual in a class, all classes derived from that class are allowed to modify or enhance the definition of the method (while retaining its original signature) providing one kind of polymorphism. In this article, we explore the virtues of virtual methods and introduce different ways of ...

The IK programming environment was designed to ease the development of distributed applications which use object-oriented concepts. The IK Run Time Support solves most of the problems introduced by distribution, such as locating and accessing objects, translating between di erent data representations or even between di erent object programming languages. This paper describes the design and impl...

In this paper we revisit the problem of achieving multi-class workload response time goals by automatically adjusting the buuer memory allocations of each workload class. We discuss the virtues and limitations of previous work with respect to a set of criteria we lay out for judging the success of any goal-oriented resource allocation algorithm. We then introduce the concept of hit rate concavi...
