Abstract

We introduce an object-oriented design pattern called Twin that allows us to model multiple inheritance in programming languages that do not support this feature (e.g. in Java, Modula-3 or Oberon-2). The pattern avoids many of the problems of multiple inheritance while keeping most of its benefits. The structure of this paper corresponds to the form of the design pattern catalogue in [GHJV95].
