Re: Re: getting all the interfaces for a class

No, my need is nothing to do with loaded classes. Sorry I am not clear with my question.

Consider the below code implementation in the target java application.


public interface A
{
public void a(int i);


public void a1(int j);
}

 public class B implements A
{
      public void a(int i)
      {
            System.out.println(i);
      }


      public void a1(int j)

      {
            System.out.println(j);
      }
}

 public class C extends B
{
      public void a(int i)
      {
            System.out.println(++i);
      }



}


 

Lets say, my need is to instrument all the methods of the classes that are of type "A". How would I know in the ClassReader level that class C is of type B & A also??

thanks,

 One way is the ClassFileTransformer implementation should keep track of the interfaces extending that interface and class that implements that interface.  Any easier solution to achieve this?
 
 
  
 There is no simple solution.
 
 I suppose you want only loaded classes not all existing classes (whatever it means).
 You can also use Instrumentation.getAllLoadedClasses()
