Abstract
Modelling object-oriented applications using collaborations and roles is well accepted. Collaboration-based or role-based designs decompose an application into tasks performed by a subset of the applications' classes. Collaborations provide a larger unit of understanding and reuse than classes, and can be an important aid in the maintenance and evolution of the software. The extraction of roles and collaborations is therefore an important issue in design recovery. Collaborations and roles are, however, not explicitly supported at source code level. Furthermore, in dynamically typed object-oriented languages, the absence of types makes the extraction of roles from the source code difficult. In this paper we present a simple approach to support the recovery of roles and collaborations. We have developed a tool which uses an execution trace of a program to find meaningful collaborations and to identify the roles that classes play in these collaborations.
