Abstract

Within one model, behavioural consistency of its constituents is often problematic. Within UML such horizontal behavioural consistency between the objects of a concrete model, is particularly needed in the context of dynamic patterns. Here, we investigate delegation, which is fundamental to patterns that separate the locality of receiving a request, and one or more localities actually handling it. We specify delegation by means of the coordination language Paradigm. In particular, we present some variants of delegation in the context of a broker pattern and clarify how the Paradigm notions are the basis for understanding a solution as well as for adapting it to deal with other dynamic features.
