Attending AOSD? Consider coming two days early to enjoy beautiful Postdam and attend FOAL. I will be giving a keynote presentation in which I will be talking about Closure Join Points and Join Point Interfaces (joint work with Milton Inostroza and Eric Tanter), and how they allow, for the first time, to define aspects that can be truly modularly type-checked and therefore are completely de-coupled from the base code they advise.
In previous work, we and others have studied how aspects can implement important cross-cutting concerns, such as runtime monitors, security monitors, and other security primitives. It is hard to design aspects that implement such concerns correctly. Therefore, once written, one desires to reuse the according aspect definitions for other systems.
In current aspect-oriented systems, however, aspects usually carry, through their pointcuts, explicit references to the base code. Those references are fragile and give up important software engineering properties such as modular reasoning and independent evolution of aspects and base code, hence hindering aspect reuse. A well-studied solution to this problem is to separate base code and aspects using an intermediate interface abstraction. Read the rest of this entry »
