MODULARITY

Support for the incremental design of aspects themselves has been neglected, even as the use of aspects in conjunction with underlying systems is gaining acceptance. The ways in which aspects can cooperate or interfere with each other need to be made ...

An effective requirements engineering (RE) approach must harmonise the need to achieve separation of concerns with the need to satisfy broadly scoped requirements and constraints. Techniques such as use cases and viewpoints help achieve separation of ...

In this paper we introduce a novel aspect oriented implementation language, called JAsCo. JAsCo is tailored for component based development and the Java Beans component model in particular. The JAsCo language introduces two concepts: aspect beans and ...

Aspects are a novel programming language feature, to express concerns in program design that crosscut traditional abstraction boundaries. The focus of this paper are dynamic aspects. Such aspects are specified as pointcut designators (patterns in the ...

We define a generic join point model for checking the Law of Demeter (LoD). Join points are trees, pointcuts are predicates over join points, and advice is checked statically similar to how declare warning is checked in AspectJ. We illustrate how the ...

The FreeBSD operating system more than doubled in size between version 2 and version 4. Many changes to primary modularity are easy to spot at a high-leveL For example, new device drivers account for 38% of the growth. Not surprisingly, changes to ...

A crosscut language is used to describe at which points an aspect crosscuts a program. An important issue is how these points can be captured using the crosscut language without introducing tight coupling between the aspect and the program. Such tight ...

We present aspect-oriented programming in Jiazzi. Jiazzi enhances Java with separately compiled, externally linked code modules called units. Units can act as effective "aspect" constructs with the ability to separate crosscutting concern code in a non-...

Aspect-oriented software development allows the programmer to identify and treat separately concerns that, subsequently, can be woven to different target applications. For this, aspect-oriented languages like AspectJ and Hyper/J provide mechanisms for ...

Join point interception (JPI), is considered an important cornerstone of aspect-oriented languages. However, we claim that JPI alone does not suffice for a modular structuring of aspects. We propose CAESAR, a model for aspect-oriented programming with a ...

Recent developments in service architectures suggest that run-time adaptations could be implemented with dynamic AOP. In this paper we discuss application requirements on run-time AOP support and present a system that addresses these requirements. We ...

Given the high proportion of HTTP traffic in the Internet, Web caches are crucial to reduce user access time, network latency, and bandwidth consumption. Prefetching in a Web cache can further enhance these benefits. For the best performance, however, ...

Persistence - the storage and retrieval of application data from secondary storage media - is often used as a classical example of a crosscutting concern. It is widely assumed that an application can be developed without taking persistence requirements ...

Middleware technologies such as Web Services, CORBA and DCOM have been very successful in solving distributed computing problems for a large family of application domains. As middleware systems are getting widely adopted and more functionally mature, it ...

From the early days of object-oriented programming, the model-view-controller paradigm has been pursued for a clear design which separates different responsibilities within an interactive application. In contrast to its untyped implementation in ...

There are two important points of view on inclusion or subtype polymorphism in object-oriented programs, namely polymorphic access and dynamic dispatch. These features are essential for object-oriented programming, and it is worthwhile to consider ...

Aspect-oriented software design will need to support languages with first-class and higher-order procedures, such as Python, Perl, ML and Scheme. These language features present both challenges and benefits for aspects. On the one hand, they force the ...

Strategic programming is a generic programming idiom for processing compound data such as terms or object structures. At the heart of the approach is the separation of two concerns: basic dataprocessing computations vs. traversal schemes. Actual ...

A development task related to a crosscutting concern is challenging because a developer can easily get lost when exploring scattered elements of code and the complex tangle of relationships between them. In this paper we present a source browsing tool ...

Aspect-oriented software development (AOSD) has primarily focused on linguistic and meta-linguistic mechanisms for separating concerns in program source. However, the kinds of concern separation and complexity management that AOSD endeavors to achieve ...
