    • interceptAndRecord

      public java.lang.Object interceptAndRecord​(org.aspectj.lang.ProceedingJoinPoint pjp, Counted counted) throws java.lang.Throwable
      Intercept methods annotated with the Counted annotation and expose a few counters about their execution status. By default, this aspect records both failed and successful attempts. If the Counted.recordFailuresOnly() is set to true, then the aspect would record only failed attempts. In case of a failure, the aspect tags the counter with the simple name of the thrown exception.
      Parameters:
      pjp - Encapsulates some information about the intercepted area.
      counted - The annotation.
      Returns:
      Whatever the intercepted method returns.
      Throws:
      java.lang.Throwable - When the intercepted method throws one.
