VTA and RTA are, by definition, whole-program analyses. They require all
the code for all the classes to be available. The classes do not have
to all be application classes; they have to be either library or
application classes. The -a switch turns the required classes from
context classes into library classes. Basically, the categories of
classes are as follows:

Application classes are both read and written by Soot.

Library classes may be read but not written by Soot.

Context classes may be inspected to see what methods and fields they
have, but the code of the methods may not be read.

Phantom classes are invented by Soot and do not correspond to any real
classes.

InvokeGraph has but getTargetsOf(SootMethod m) and
getTransitiveTargetsOf(SootMethod m).
