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.. ]]
