Aspects are defined as well-modularized crosscutting concerns. Despite being a core tenet of Aspect Oriented Programming, little research has been done in characterizing and measuring crosscutting concerns. Some of the issues that have not been fully explored are: What kinds of crosscutting concerns exist? What language constructs do they use? And what is the impact of crosscutting in actual As...

Aspect Oriented Software Development has been proposed as a means to improve modularization of software in the presence of crosscutting concerns. Compared to object-oriented or procedural approaches, Aspect Oriented Programming (AOP) has not yet been applied in many industrial applications. In this thesis we investigate the application of AOP within an industrial context and propose a novel sol...

Modelling adaptive Web applications is a difficult and complex task. Usually, the development of general system functionality and context adaptation is intertwined. However, adaptivity is a cross-cutting concern of an adaptive Web application, and thus is naturally viewed as an aspect. Using aspect-oriented modelling techniques from the very beginning in the design of adaptive Web applications ...

While Aspect-oriented programming (AOP) [Kic+97] enables modularization of crosscutting concerns, Reflection [Smi82] is commonly recognized as a valuable instrument for separation of concerns [Coi99]. In this short paper, we explore the relationships between reflection and AOP. This study is carried out in the context of a project about dynamic adaptability of distributed systems [RNTL00]. We p...

Aspect Oriented Programming (AOP) aims to ease maintenance and promote reuse of software components by separating core concerns from crosscutting concerns: aspects of a program that cannot be conned to a single program component. In AOP languages such as AspectJ, this kind of concern is encapsulated in an aspect and connected to main classes using pointcuts. This removes extraneous code from th...

Executable Domain-Specific Languages (DSLs) are used for defining the behaviors of systems. In particular, the operational semantics of such DSLs may define how conforming models react to stimuli from their environment. This commonly requires adapting the semantics to define both the possible domain-level stimuli, and their handling during the execution. However, manually adapting the semantics...

The identification of crosscutting is a prerequisite for applying aspect-oriented techniques in software development. We present an operationalization of the definition of crosscutting to support this identification. We use matrices to represent the relation between design elements at different levels of abstraction. We present some case studies about the identification of crosscutting concerns...

The correctness of a component-based specification is not guaranteed by the correctness of its components alone; on the contrary, integration analysis is needed to observe their conjoint behavior. Existing approaches often leave the results of the analysis at the level of the integrated system, without tracing them onto the corresponding components. This effectively results in loss of architect...

An Aspect Oriented approach to implement fault detection in automatic measurement systems is proposed. Faults are handled by means of “aspects”, a specific software unit to better modularize issues transversal to many modules (“crosscutting concerns”). In this way, maintainability and reusability of a measurement software are improved: indeed, once a modification of the fault detection policy o...

Modularity is a key concept that programmers wield in their struggle against the complexity of software systems. The implementation of crosscutting concerns in a traditional programming language (e.g. C, C#, Java) results in software that is difficult to maintain and reuse. Although modules have taken many forms over the years from functions and procedures to classes, no form has been capable o...
