Re: 答复: 答复: how to deal with existing java file or class file?

Hi Helen,

I'd suggest to read our PLDI'03 tutorial, which has more details on soot
internal structures and how a class file is parsed and soot internal
representation is constructed.

Sootify means the construction of soot internal representation for
.class. The internal representation of a class is SootClass, and
SootMethod for method, JimpleBody for method body, and so on. After
loadClassAndSupport, you can iterate over methods of a class. But the
JimpleBody for the method body may not be constructed yet, you need to
call "retrieveActiveBody" on a SootMethod.

There are several output format of soot, if you donot choose to
overwrite original classes, you have a new sootified class file.

Yes.
