Without creating a aspectj shadow class that gets "injected" via an intertype declaration, I don't see a way to do it without reflection and/or using the map approached referenced in your post.

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.. ]] [[ http://stackoverflow.com/questions/6698203/exposing-previous-value-in-aspectj-set-pointcut - this discussion stores all the fields in a single map - i dis like solution for performance.. ]] TIA
