JAssignStmt with reference to a class field as right-hand-side

[Emil Slusanschi <slusanschi@sc.rwth-aachen.de>]

Hi,

I want to know how can I generate a JAssignStmt that contains a 
reference to a class field as the right-hand-side.

I have a class:

class MyType{
    public double value;
    public double stress;

    public MyType(){
         super();
         return;
    }
}

and I want to generate in Jimple something like

$d0 = r0.<MyType: double value>
$d1 = r0.<MyType: double stress>

where $d0 and $d1 are locals (doubles) and r0 is of type MyType. I have 
all the locals in hand, that is $d0, $d1 and r0 but how do I get from r0 
the reference to his fields?

I have something like this in my Body Transformer:


derivUnits.insertAfter(Jimple.v().newAssignStmt(local_for_$d0,local_for_r0.???,stmt);

derivUnits.insertAfter(Jimple.v().newAssignStmt(local_for_$d1,local_for_r0.???,stmt);

and the problems are obvious the ??? ;-)

Any ideeas? And yes, where in the docs should I look in the future to 
find these kind of infos?

Thanks,

Emil
