[aspectj-users] Adding a new buddy field for EVERY existing field in a c

[y a <yaniv.azriel.samsung@xxxxxxxxx>]

I want an aspect to store the old value for each field set operation

So if a class has 3 long fields, i now need 3 new fields in the aspect

Is this possible ?!

And is there a suitable ajc syntax to access such a buddy field in a set() advice ?

my example:

aspect to  "print" the field changes, but i need the new fields to "store" the values

import java.io.*;
import org.aspectj.lang.reflect.FieldSignature;

aspect AspectField  {
      before(long newval): set(long *) && args(newval) {
     
         FieldSignature fs;
         fs = (FieldSignature)thisJoinPointStaticPart.getSignature();
         System.out.println(fs.getFieldType());
         System.out.println("FIELD SET TO " + newval); 

         // i want to store the newval here in a "buddy field"

      }
  }

[[ Eventually i want all of this to be done statically with out reflection but one bridge at a time.. ]]
