Code implementing a crosscutting concern is often spread over many different parts of an application. Identifying such code automatically greatly improves both the maintainability and the evolvability of the application. First of all, it allows a developer to more easily find the places in the code that must be changed when the concern changes, and thus makes such changes less time consuming an...

Crosscutting is usually described in terms of scattering and tangling. However, the distinction between these concepts is vague, which could lead to ambiguous statements. Sometimes, precise definitions are required, e.g. for the formal identification of crosscutting concerns. We propose a conceptual framework for formalizing these concepts based on a crosscutting pattern that shows the mapping ...

In current composition languages for web services, there is insufficient support to explicitly separate crosscutting concerns, which leads to compositions that are hard to maintain or evolve. A similar problem in object-oriented languages is being tackled by aspect-oriented programming, and some work has been started to apply these techniques to web service composition languages as well. We ide...

The aspect-oriented paradigm can help promoting system modularity and maintainability by separating crosscutting concerns as aspects. However, weaving an aspect may introduce undesired impacts on the original system behavior. We present an approach to analyzing the influences of an aspect weaving on the base model. The analysis is based on the behavioral equivalence between the base model and i...

Programmers use assertion to enforce design by contract. However, in Object-Oriented Programming, assertion has few drawbacks. One drawback is that assertion may prevent the reuse of a class. Another is that programmers cannot express assertion about inter-object relations. Using Aspect-Oriented Programming technique, which enables to describe a crosscutting concern in one module, programmers c...

Aspect-orientation provides a new way of modularization by clearly separating crosscutting concerns from non-crosscutting ones. While aspect-orientation originally has emerged at the programming level, it now stretches also over other development phases. There are, for example, already several proposals to Aspect-Oriented Modeling (AOM), most of them pursuing distinguished goals, providing diff...

This dissertation presents a query-based browsing tool called Q JBrowser that can assist developers in working with crosscutting concerns. Although there is no apparent limit to the number of different kinds of crosscutting views of source code that are potentially interesting to developers, many existing browser tools are capable of producing only a limited set of pre-defined views. This is be...

Aspect Mining and Refactoring to Aspects aim to identify crosscutting concerns and encapsulate them in aspects, respectively. Aspect Mining remains as non-automatic process, i.e., the user needs to analyze and understand the results generated by techniques/tools, and confirm crosscutting concerns to refactor them to aspects. In this paper we propose a visual approach that deals with results gen...

This paper presents an extension of the Klagenfurt Conceptual Predesign Model (KCPM) allowing taking into account the non-functional requirements to the system. These requirements are treated as crosscutting concerns. This process could be also seen as an addition to the AOSD paradigm that brings the gap between the Aspect-Oriented Requirement Engineering and Aspect-Oriented Modeling. The exten...

In this position paper, we argue that traditional object-oriented design patterns can be regarded as workarounds for limitations in current programming languages, including crosscutting concerns. Aspect-oriented programming (AOP) is able to modularise crosscutting concerns and overcomes many of the limitations. To illustrate, we mention a few examples. We describe several situations in which pa...
