CAT: A Toolkit for Assembling Concerns

Aspect-oriented software development (AOSD) includes separating concerns, and then composing or weaving them to produce software that realizes appropriately-combined behavior. This might involve composition of two or more class hierar-chies, for example, or weaving of aspect code into base code. Composition or weaving can be defined, specified and implemented in a wide variety of ways, and can be applied to software artifacts of various kinds. Yet, despite these differences, there are important similarities. The thesis of this paper is that an abstraction layer and toolkit supporting low-level concern assembly would enable AOSD tool builders to leverage many of these similarities, reducing development effort and increasing the scope and interoperation of their tools.
