AspectWerkz
is a dynamic, lightweight and
high-performant AOP framework for Java.
AspectWerkz
offers both power and simplicity
and will help you to easily integrate AOP in both new and
existing projects.
AspectWerkz
utilizes bytecode
modification to weave your classes at project build-time, class load time or runtime. It hooks in
using standardized JVM level APIs.
It has a rich and highly orthogonal join point model. Aspects, advices and
introductions are written in plain Java and your target
classes can be regular POJOs.
You have the possibility to add, remove and re-structure
advice as well as swapping the implementation of your
introductions at runtime.
Your aspects can be defined using either Java 5 annotations,
Java 1.3/1.4 custom doclets or a simple XML definition
file.
AspectWerkz
provides an API to use the very same aspects for proxies, hence
providing a transparent experience, allowing a smooth transition
for users familiar with proxies.
AspectWerkz
performance is reported in this separate project.
AspectWerkz
is Free Software. The
LGPL-style license allows the use of
AspectWerkz 2.0
in both commercial and open source projects.
