RE: [aspectj-users] Passing parameters

Please note that the following code compiles does not get woven. If I take the event parameter out, it compiles and gets woven.

The following is the method I want to wrapper with advice:

protected static State processEvent(ClientSession clientSession, State state, Event event)

throws com.ereinsure.commons.exception.PlatformException

{

…

}

ClientSession, State, Event all exist within the same package and I do import those classes.

here is my simplified aspect code:

pointcut callProcessEvent(Event e) :
    call(State processEvent(..)) && args(e);

before(Event event) : callProcessEvent(event)
{
      System.out.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Before call of processEvent aspect");
      System.out.println("Start Time in millis: " + System.currentTimeMillis());
}

after(Event event) returning : callProcessEvent(event)
{
      System.out.println("<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< After call of " + event.getName() + " aspect");
      System.out.println("End Time in millis: " + System.currentTimeMillis());
}

Hi Ed,

Can you give us some example code? Are there any compiler warnings? Did you import the types? What is the signature of the execute method you are hoping to match?

You can use:

pointcut notifyExecute(Event e) :
call(StateTransition execute(..)) && args(e,...);

in that case. (assuming “e” is the first parameter)

I tried that along with target(e). The aspect compiles but does not get woven.

There are three params that get passed into the method execute(). Do all three need to be passed into the notifyExecute pointcut?

Try something like…

pointcut notifyExecute(Event e) :
call(StateTransition execute(..)) && args(e);

after(Event event) returning : notifyExecute(event) {
System.out.println("<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< Call after Execute aspect");
System.out.println("End Time in millis: " + System.currentTimeMillis());

ystem.out.println(“Event was: “+event);
}

I am trying to pass parameters from the point cut into the after advice.

My point cut gets the correct classes that I wish woven. The problem is getting the values passed in to point cut into the advice.

Simply:

pointcut notifyExecute() :
call(StateTransition execute(..));

after() returning : notifyExecute() {
System.out.println("<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< Call after Execute aspect");
System.out.println("End Time in millis: " + System.currentTimeMillis());
}

There is an Event param that gets passed into the execute method and I would like to get access to the object within the after advice.
