Aspect-oriented programming addresses the problem that the implementation of some properties such as error handling and optimization tends to cross-cut the basic functionality. To overcome that problem special languages are used to specify such properties—the so-called aspects—in isolation. The software application is obtained by weaving the aspect code and the implementation of properties corr...

The study investigated technology innovations and factors influencing its upgrading in the indigenous textile weaving firms in southwestern Nigeria. Data for the survey was sourced from 300 small scale firms with 91% retrieval rate. The survey instruments which were questionnaire, interview and personal observation elicited information on the weaving process. Majority (89%) of the respondents r...

Teacher educators have a very daunting task requiring currency in their discipline, curricular, policy and institutional imperatives as well as pedagogical and cultural issues. Tertiary institutions are facing increasing expectations to cater for and increase retention of underrepresented groups, whilst class sizes increase and face-to-face contact decreases. This paper outlines a case study of...

Weaving models are used in the model driven engineering (MDE) community for various application scenarios related to model mappings. However, an analysis of its suitability for specification of heterogeneous schema mappings reveals that weaving models lack support for mapping rules and, therefore, cannot prevent mapping specifications which are semantically meaningless, wrong or disallowed. Thi...

Introducing aspect orientation to a polymorphically typed functional language strengthens the importance of type-scoped advices; i.e., advices with their effects being harnessed by type constraints. As types are typically treated as compile time entities, it is desirable to be able to perform static weaving to determine at compile time the chaining of type-scoped advices to the invocations of t...

When late-binding of advice is used for incremental development or configuration, implementing advice weaving using code rewriting external to the VM can cause performance problems during application startup. We present an interpreter-based (non-rewriting) weaver that uses a simple table and cache structure for matching pointcuts against dynamic join points together with a simple mechanism for ...

Modular development of ontologies proves beneficial at different stages of the ontology lifecycle. In our previous work, we proposed aspect-oriented ontology development as a flexible approach to modular ontology development and a-posteriori modularization of existing monolithic ontologies, inspired by aspect-oriented programming and based on so called cross-cutting concerns. Similar to other f...

This paper reports on the development of an Aspect-Oriented Modeling engine and its initial deployment within the ModelDriven Engineering environment used in production at Motorola. The development environment is presented in detail, through a small example, and the current state of Aspect-Oriented Software Development technologies are discussed in this context. The report presents the particul...

Runtime monitoring, where some part of a program’s behavior and/or data is observed during execution, is a very useful technique that software developers to use for understanding, analyzing, debugging, and improving their software. Aspect oriented programming is a natural fit for supporting the wide ranging instrumentation needs of runtime monitoring, but so far the limitations of AOP framework...

Aspect-Oriented Programming (AOP) addresses limitations in the Object-Oriented (OO) paradigm relating to modularisation of crosscutting behaviour. In AOP, crosscutting behaviour is expressed as aspects that are integrated with a base program through a weaving process. Many language-specific AOP models already exist, requiring the programmer to work with a single language for base and aspect pro...
