[Soot-list] Is there a way to get the object whose method is being called?

[Eric Bodden]

Hi Clarissa.

As Zheng wrote, you cannot determine the object. But possible what you
actually mean is the variable holding that object at runtime. In this
case you can get a handle to this variable as follows:

1.) extract the call statement from the call edge
2.) on this stmt perform stmt.getInvokeExpr() to extract the invoke expression
3.) cast this invoke expression to an InstanceInvokeExpr on which you
can then call getBase()
4.) getBase() returns a value, which you should be able to cast to a
local variable

Cheers,
Eric
