[ews.eclipse.technology.aspectj] QUESTION: Class wrapping at runtime FEA

["John Cage" <ahanys@xxxxxxxxx>]

Hi,

I want to ask if this should be possible:

In VM is a class named "SessionImpl" which implements interface Session.
For example we say tha Session interface has only one method called "open".

I want to wrap SessionImpl this way: that before calling to this method 
something happens and after also.
So I want to change this method byte code, which is loaded in VM.

so I specify something like this to achieve that:

RuntimeAspect extends SessionImpl implementing Session {
    /* Here is an empty param list, but other methods can have*/
    before: public void open() {
         System.out.println("before call of open() on each object of type 
SessionImpl");
    }

    /* Here is an empty param list, but other methods can have*/
    after: public void open() {
         System.out.println("after call of open() on each object of type 
SessionImpl");
    }

}

This wrapping can be done programmatically directly from code.
Example:
if (obj iswrapped by RuntimeAspect) {
   wrap(obj, RuntimeAspect.class);
} else {
   System.out.println("obj is already wrapped :-)");
}
// END


Wrapping could be applied on an specific interface. Wrapping can have 
limited namespace. etc...
Is something like this alredy present in AspectJ? If not should it be a plan 
to do this in a future?

Thanks John
