Hi desperate student,

 

All the classes that start with J are implementations of the respective interfaces. A \
Soot user should never reference them explicitly, only the interfaces, e.g., use \
InvokeExpr instead of JInvokeExpr. To construct instances of these types use \
Jimple.v().newXXX(). The Jimple singleton class contains factory methods for all the \
different Jimple language constructs.

 

Now let's move on to method references. You first need to get hold of the method you \
want to reference. The SootMethod class has a method called makeRef() to then create \
a reference. To get a method, use Scene.v().getMethod(). You can also take a \
SootClass and get the method from there, that's equivalent.

 

A Value is essentially the base class of everything that can be used as an expression \
in Soot. It can be some constant, an invoke expression, or a "this" reference. Get a \
"this" reference, once again grab the SootMethod and then call \
method.getActiveBody().getThisLocal() on it.

 

Best regards,

  Steven

Betreff: [Soot-list] Soot Instrumentation

 

Dear Sir or Madam,

 

i have to use the manual instrumentation function of Soot via java code. There are \
two problems, which i can īt solve: the constructor of "JStaticInvokeExpr" needs 2 \
parameter:

-a "SootMethodRef": where can i get this from? its just a interface and there is no \
class called "soot.SootMethodRefImpl" (i backtracked my jimple code and one \
"JStaticInvokeExpr" instance had a parameter with this class)

-a List of Values: first should be in my case a this reference- how can i access a \
this reference dynamically?? "soot.jimple.This.Ref" constructor needs "RefType" as \
input and "RefType" constructor needs "Singletons.Global" as input. Something like \
"ThisRef thiss=new ThisRef(new RefType(Singletons.Global));" doesn īt work.

 

Yours sincerely,

 

a desperated student
