Using Interaction Patterns for Making Adaptors among Software Components

Recycling components reduces the development cost and time during the creation of a software system. Nevertheless, combining components is not a simple task. It demands to the candidate components to be adequate and then to be adapted inside the environment where they are going to be integrated. For this, it is necessary to study the existing relationships among the services offered by one selected component and the services required by the system. Sometimes, these relationships need the use of adaptors in order to allow us to establish the correct correspondence among the elements involved. Without these adaptors, the interoperability among these components could be impossible. This paper presents the synthesis of the interaction patterns obtained from UML sequence charts and their codification by means of cycling oriented labeled graphs. This kind of patterns offers some innovations like the inclusion of options like horizontal composition, coregions, gates and fragments. These options will facilitate the tasks of systems verification and systems simulation. The results obtained from these simulations, will be used to facilitate the creation of adaptors among components that have difficulties to interoperate.
