Dynamic Weaving for Building Reconfigurable Software Systems

Aspect-oriented technology is a programming paradigm that provides the user with the ability to modularize the representation of crosscutting concerns in order to maximize reusability and ensure flexibility of the software system. In this position paper we present the dynamic Weaver Framework (DWF), which is an aspect-oriented framework that supports the dynamic attachment and detachment of aspects to components at run-time, as well as the capability to add and remove aspects and pointcuts during runtime. This capability is the prime factor that enables us to support reconfigurability of the software system. The need to adapt to environmental changes and cope gracefully with the challenges that may have an impact on performance degradation, safety and liveness properties of the running system requires recongfigurability of both the functional and aspectual properties of the system software.
