Topics for exam in AOSD Basic concepts: tangling, scattering, joinpoint, advice, cross-cutting, weaving AspectJ: syntax, pointcut notations, around, proceed, AJDT environment Categories of aspects: spectative, regulative, weakly/strongly invasive Specifications of aspects: temporal logic (just what was in examples), assume-guarantee for system before/after weaving Requirements and design for aspects: Arcade and Concern diagrams; requires/provides for UML (again, not beyond what was shown)

Topics (cont.) EAOP: “observer” computation model, dynamic ordering and aspect instantiation (in tree), dynamic examples Composition filters: basic model; error, dispatch, Meta filters; examples given Correctness of aspects: once-and-for-all model checking (MAVEN approach), pointcut ready, weaving models Interference among aspects: kinds of interference, Introductions and interference, common join points, specification-based interference, proving interference- freedom Middleware and AOP: JBoss AOP, interceptors, using XML for binding, Java-based aspects Metrics for AOP: general concepts, and what has been done

Summary Aspects can treat real problems in a modular, reusable way Interesting ideas on modularity, compositionality Several language possibilities (we only saw a few) May create new problems in correctness Gaining acceptance in middleware, product lines, debugging, security Still not mainstream, but worth considering Thanks—it was fun…
