Presentation Transcript

  1. 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)

  2. 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

  3. 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…
