Aspect Oriented Programming

Aspect Oriented Programming (AOP) is a programming paradigm that aims to increase modularity by allowing the separation of cross-cutting concerns. It does so by adding additional behavior to existing code without modifying the code itself, instead separately specifying which code is modified via a 'pointcut' specification, such as “log all function calls when the function's name begins with 'set'”. This allows secondary behaviors (eg logging) to be added to a program without cluttering the meaty code that's core to the functionality.

Design

• The AspectConfiguration specifies which aspect applies to which method of an object
• Each aspect is essentially a method (or a separate class containing a group of those aspect-methods) written in an aspect-oriented language (or annotation, or through an idiom in an existing language).
• Aspects are wrapped 'before', 'after' or 'around' methods. For example we...
