Re: [abc-users] adding jimple

Apologies I was not clear in my last email. Here is what i have
===============
myFoo= helperClass.getMethod("int myFoo()");
Local result=localgen.generateLocal(IntType.v(),"var1");
InvokeExpr incExpr= Jimple.v().newStaticInvokeExpr(myFoo.makeRef());
===============

My problem is that I cant seem to get the return value into the Local
*result*. Should I be using something else??
