Re: [aspectj-users] Dynamic type casting

["Venkat Dosapati" <venkat@xxxxxxxxxxxxxxxxx>]

Sorry, my previous mail was missing the question. Here are the full details with the question:

Please see the question in the end.

==============MyAspect.java====================
public aspect MyAspect {

 Object around() : execution(* *.load(..)) {
  Object receiver = thisJoinPoint.getThis();
  String className = receiver.getClass().getName();
  Object[] args = getArguments(thisJoinPoint);
  System.out.println("Class:" + className + "::ARGS:" + args);

  Object returnValue = myapp.PersistenceHandler.load(className, args); /*
Here I get common Object, but the Object is 'className' type. */
  return returnValue;
 }

 private Object[] getArguments(JoinPoint jp)
 {
  Object[] argumentValues = jp.getArgs();
  return argumentValues;
 }
}
===============================================


================Class A=========================
public class A {

    public A load(int id) {
        // no implementation
        return null;
    }
}
================================================


================Class B=========================
public class B {

    public B load(int id) {
        // no implementation
        return null;
    }
}
===============================================



When I replace the load() method in 2 classes A & B with my aspect, the
advice is returning the common Object. But the classes A & B should return
their respective type object.

how can I type caste the Object to its original class in my aspect like
this:

Object returnValue = myapp.PersistenceHandler.load(className, args);
return (className) returnValue;  /* Here className is the variable for the
class name */

[I think it is not possible with JAVA. Is it possible with AspectJ?]


Thanks in advance!
