[Soot-list] Class field in call graph

[Steven Arzt]

Hi Yasmin,

 

This is pretty easy to do. You only need to to iterate over the the units in all bodies of all methods in all classes and check whether there is a reference to the field you are looking for.  That should be sufficient for your use case.

 

Best regards,

  Steven

Betreff: [Soot-list] Class field in call graph

 

Hello,

I am new to Soot, and until now I have successfully used Soot to generate a call graph. As far as I know, the call graph only shows the calling relationship between methods (which I think is supposed to be).
However, what I’m interested in is to find out which methods call/access some certain class fields. Hence my question is, can I obtain the class field in the call graph as well? For example, if I have a class field named xPos, then I would like to have the call graph to have a node for xPos and find which methods call/access xPos. Of course if the class field have setter and getter, it will not be a problem, but this is not always the case.
If it’s not possible, is there any way to extend any classes of Soot to do it? Or do I need to do other kind of analysis to obtain that information?

Thank you.

Best regards,
Yasmin
