Examples of org.jboss.aop.advice.Interceptor

org.jboss.aop.advice.Interceptor
Intercepts one or more joinpoints.
The {@code Interceptor} is a specific type of aspect, that contains onlyone, well defined advice, the {@code invoke} method. Because of that, an{@code Interceptor} is also referred to as an advice.

      // TODO we assume there is only one interceptor now.
      Interceptor[] interceptors = advisor.getInterceptors();
      // Step Check for cross references
      for (int i = 0; i < interceptors.length; i++) {
         Interceptor interceptor = interceptors[i];
         if (interceptor instanceof BaseInterceptor) {
