Aspect-Oriented Programming (AOP)
Motiviations (http://aopalliance.sourceforge.net/motivations.html)
Aspect-Oriented Programming (AOP) is a programming technique that will be able to enhance several existing middleware environments (such as J2EE), or development environements (e.g. JBuilder, Eclipse).
Several projects now provide AOP-related techniques such as generic proxies, interceptors, or bytecode translators.
- ASM: a lightweight bytecode translator.
- AspectJ: an AO source-level weaver. New Language.
- AspectWerkz: an AO framework (bytecode-level dynamic weaver+configuration).
- BCEL: a bytecode translator.
- CGLIB: high-level API for class artifact manipulation and method interception.
- JAC: an AO middleware (bytecode-level dynamic weaver+configuration+aspects). Framework.
- Javassist: a bytecode translator with a high-level API.
- JBoss-AOP: interception and metadata-based AO framework.
- JMangler: a bytecode translator with a composition framework for translations.
- Nanning: an AO weaver (framework).
- Prose: an AO bytecode-level dynamic weaver (framework).
