Examples of org.codehaus.aspectwerkz.advice.AbstractAdvice

org.codehaus.aspectwerkz.advice.AbstractAdvice
Abstract base class for all advice classes. Is invoked after that a specific join point has been executed.
Supports four different deployment models: PER_JVM, PER_CLASS, PER_INSTANCE A PER_THREAD.
The PER_JVM deployment model performance a bit better than the other models since no synchronization A object creation is needed. @see aspectwerkz.DeploymentModel @author Jonas Bon�r
