Re: What is signature class?

[Liang Guo <lguo@mail.eecis.udel.edu>]

yes, the "cannot setActiveBody error" was raised when trying to
setActiveBody for the Class Initialization method clinit(), not for
abstarct method.

Can you tellme what is the Context class and signature class? Is this
clinit() one of the context class?

You suggested me to invoke my slicer through Soot.Main, and your replies
to my questions always involve this Soot.Main. What is the procedure to
make this work, I mean how to start any Java program based on soot through
Soot.Main? 'Cause this solution to my problem of context class seems
to need me to use this Soot.Main. So, Thanks a lot for your comments
and time. :-))
