“…Inspired by these categories, Djoko Djoko et al [10] have recently proposed to capture observer, aborter and confiner aspects directly in the language under consideration. Namely for each category, they define a specific aspect language with the property that any aspect written in that language belongs to the category.…”

Oliveira and colleagues recently developed a powerful model to reason about mixin-based composition of effectful components and their interference, exploiting a wide variety of techniques such as equational reasoning, parametricity, and algebraic laws about monadic effects. This work addresses the issue of reasoning about interference with effectful aspects in the presence of unrestricted quantification through pointcuts. While global reasoning is required, we show that it is possible to reason in a compositional manner, which is key for the scalability of the approach in the face of large and evolving systems. We establish a general equivalence theorem that is based on a few conditions that can be established, reused, and adapted separately as the system evolves. Interestingly, one of these conditions, local harmlessness, can be proven by a translation to the mixin setting, making it possible to directly exploit previously established results about certain kinds of harmless extensions.

“…Some ways of determining the category of the aspect using code analysis, dataflow techniques and semantic definitions are described in [7,11,13,3]. If none of them gives a positive answer, the algorithm presented below can help to determine whether the aspect is uniformly strongly invasive, i.e., is always strongly invasive for every possible base system to which it can be woven.…”

An extended specification for aspects, and a new verification method based on model checking are used to establish the correctness of strongly-invasive aspects, independently of any particular base program to which they may be woven. Such aspects can change the underlying base program variables to new states, and after the aspect advice has completed, the base program code continues from states that were previously unreachable. The needed changes in the MAVEN model checker are described, and the soundness of the verification method is proven. An example is shown of its application to aspects that provide various bonus points to student grading programs.

“…The programmer may have to inspect the woven program (or debug its execution) to understand its semantics. In a previous article [6], we have considered several categories of aspects that alter the semantics of the base program in a tightly controlled manner. For each category of aspects A x , we have identified a corresponding class of properties ϕ x that is preserved by weaving these aspects.…”

Aspect oriented programming can arbitrarily distort the semantics of programs. In particular, weaving can invalidate crucial safety and liveness properties of the base program. In previous work, we have identified categories of aspects that preserve classes of temporal properties. We have formally proved that, for any program, the weaving of any aspect in a category preserves all properties in the related class. In this article, after a summary of our previous work, we present, for each aspect category, a specialized aspect language which ensures that any aspect written in that language belongs to the corresponding category. It can be proved that these languages preserve the corresponding classes of properties by construction. The aspect languages share the same expressive pointcut language and are designed w.r.t. a common imperative base language. Each language is illustrated by simple examples. We also prove that all aspects written in one of the languages belong to the corresponding category.
