Re: [aspectj-users] aspectj capturing currently executing object

[Krishna Jasty]

Thanks Andy,

 

It started working for me too, the only thing i did is i changed before advice to after advice, then it started showing me the target object information.

Thanks,

This works for me:

aspect Aspect {

  pointcut allConstructors() : call( * java.util..add(..));

 Object around() : allConstructors() {

   Object[] objarr = thisJoinPoint.getArgs();

   for (int i = 0; i < objarr.length; i++) {

   System.out.println("object is..."+objarr[i]);//This will give me tha value "abc"

   }

   System.out.println(((Vector)thisJoinPoint.getTarget()).size());

   Object x = proceed();

   System.out.println(((Vector)thisJoinPoint.getTarget()).size());

   return null;

  }

}

it prints 0 and 1 for the size of the target vector. Is that how you were using getTarget()?

Hi Users,

Go through the following steps once.

 

1) My Java class code

 

  public static void main(String[] args)throws IOException,SQLException

{
     Vector testvector = new Vector();
      testvector.add("abc");
   }

 

 

2) Aspect Implementation

 

 pointcut allConstructors() : call( * java.util..add(..));

 Object around() : allConstructors() {
 Object[] objarr = thisJoinPoint.getArgs();

 for (int i = 0; i < objarr.length; i++)

{
  System.out.println("object is..."+objarr[i]);//This will give me tha value "abc"
 }

 

Similarly if i want to get the object testvector and i want to perform the testvector.size() operation on it.
How to capture this testvector object, if i use this or getTarget() which is returning null.

Please suggest the way to make it possible.
