[Soot-list] Instrument Class to print HashCode

[Marc-André Laverdière]

Hi Utkarsh,

I am not sure I understand your question precisely, but I'm going to
give my best shot.

If you want to find all the objects that receive assignments, you just
have to iterate and find all the AssignStmt instances, cast it, and
return the left object.

In Scala, it'd be something like this: sm.units.collect { case a :
AssignStmt => a.getLeftOp}

Then you can do whatever you want with those, like calculating a hash code.

Same principle in Java, just way more verbose ;-)
