[Soot-list] Call-Graph target edge - Determining target class

[Eric Bodden]

Hi John.

Yes, this is possible. The easiest way should be like this:

Define a filter over the edges. You can do so by subclassing this class:
http://www.sable.mcgill.ca/soot/doc/soot/jimple/toolkits/callgraph/Filter.html

Then the filter can check if the declaringClass of the target is an
applicationClass:
target.getDeclaringClass().isApplicationClass()

That should be all.
