SUMMARY In the conventionalobject model, encapsulated objects interact by messages that result in method invocations on the destination object. A message is delivered directly at the destination object. As a result of the direct deliveries, the message control code performing intermediate message manipulations cannot be abstracted out separately from the(More)
—Parallel computing on interconnected workstations is becoming a viable and attractive proposition due to the rapid growth in speeds of interconnection networks and processors. In the case of workstation clusters, there is always a considerable amount of unused computing capacity available in the network. However, heterogeneity in architectures and(More)
A concept lattice based approach for analysis of class cohesion is presented. The approach facilitates rapid identification of less cohesive classes. It also helps identify less cohesive methods, attributes and classes in one go. Further, the approach guides refactorings such as extract class, move method, localize attributes and remove unused(More)
Weyuker's Property 9 has received a mixed response regarding its applicability to object oriented software metrics. Contrary to past beliefs, the relevance of this property to object oriented systems is brought out. In support of the new argument, counterexamples to earlier claims are formulated and two new metrics highlighting a notion of complexity that(More)
Maintenance downtime and overheads for applying patches are major concerns for systems requiring round the clock availability. Hence, methods for carrying out dynamic updates are needed. However, correctness of the system during and after every dynamic update needs to be ensured. This paper defines two safety criteria, type consistency and isolation of(More)
It is observed that most object oriented coupling metrics are macroscopic, which makes them unsuitable for making finer refactoring decisions. The notions of microscopic viewpoints and coupling projections are introduced. Existing metrics are classified in terms of viewpoints and projections. Two microscopic metrics called relative method coupling (RMC) and(More)
