“…Katz et al [33], for instance, discuss the role of 'invasive aspects' in software maintenance (explored in task 3). The problem of 'invasive aspects', although realized through different implementation mechanisms, have their counterparts in hybrid FOP languages [32] (e.g., CaesarJ), composition filters [4], and delta-oriented programming [35].…”

A considerable part of software design is dedicated for the composition of two or more modules. The implication is that changes made later in the implementation often require some reasoning about module composition properties. However, these properties are often not explicitly specified in design artefacts. Moreover, they cannot be easily inferred from the source code either. As a result, implicit composition properties may represent a major source of software maintenance complexity. This fact is particularly true with the advent of post object-oriented techniques, which are increasingly providing advanced mechanisms to enable flexible module composition. However, there is little empirical knowledge on how design models with explicitly-specified composition properties can improve software maintenance tasks. This paper reports an experiment that analyses the impact of design models enriched with composition properties on system maintenance. Explicit composition modelling was achieved in the experiment through a conservative approach, i.e., a specific set of additional UML stereotypes dedicated to model composition properties. The experiment involved 28 participants, who were asked to realize four maintenance tasks using UML design models with different levels of module composition details. Our findings suggested that explicit composition modelling contributed to better results in the realization of program change tasks, regardless of the developers' expertise. Users of composition-enhanced models consistently yielded better results when compared to users of plain UML models. The use of explicit composition specification also led to an average increase of 44.7% in the quality of changes produced by the participants.

“…In [10], verification is shown for strongly-invasive aspects, by adding an assumption U about the base system states previously unreachable that now can occur in the woven system after aspect advice completes. A relatively complex modular verification technique is given that treats sequential weaving without joinpoints in advice.…”

In this work we consider specification and compositional verification for interference detection when several aspects are woven together under joint-weaving semantics without recursion. In this semantics, whenever a joinpoint of an aspect is reached, the corresponding advice is begun even if the joinpoint is inside the advice of other aspects. This captures most of the possible aspect interference cases in AspectJ. Moreover, the given technique is used to capture cooperation among aspects, which enhances modularity. The extended specification and proof obligations should provide insight to the possible interactions among aspects in a reusable library.

“…Pointcuts and return states are described using ltl expressions (however, pointcuts can only use current-state expressions, past ltl syntax is not supported). Their work is extended in [14] to support strongly-invasive aspects.…”

We present AspectLTL, a temporal-logic based language for the specification and implementation of crosscutting concerns. AspectLTL enables the modular declarative specification of expressive concerns, covering the addition of new behaviors, as well as the specification of safety and liveness properties. Moreover, given an AspectLTL specification, consisting of a base system and a set of aspects, we provide AspectLTL with a composition and synthesis-based weaving process, whose output is a correct-by-construction executable artifact. The language is supported by a prototype tool and is demonstrated using a running example.
