Abstract:
In real applications, design patterns are almost always to be found composed with each other. Correct application of patterns therefore relies on precise definition of these compositions. In this paper, we propose a set of operators on patterns that can be used in such definitions. These operators are restriction of a pattern with respect to a constraint, superposition of two patterns, and a number of structural manipulations of the pattern's components. We also report a case study on the pattern compositions suggested informally in the Gang of Four book in order to demonstrate the expressiveness of the operators.
