Modular Hot Spots: A Pattern Language for Developing High-Level Framework Reuse Interfaces using Aspects

Applications based on an object-oriented framework can be built by programming against the framework’s reuse interface. Mastering a framework is typically a time-consuming and difficult task. This paper presents a pattern language for developing higher level reuse interfaces for an existing framework. When applying the patterns that constitute the language it is implied that the framework becomes enhanced with an additional layer of reusable modules that rely on aspect-oriented programming. These modules are referred to as Modular Hot Spots. They modularize existing hot spots, enabling a framework-based application to be built in a stepwise way and at a higher abstraction level than if using the conventional reuse interface. By raising the abstraction level, it is intended that the development of framework-based applications becomes facilitated.
