[Soot-list] Equality of SootMethod

[Denis Bogdanas]

I had the same question before. Some confusion might come because soot does
not distinguish between method declarations and method references. Both are
SootMethod. Yet both are managed by soot and "GENERALLY" there's one single
instance for any individual method signature. As long as you don't try to
instantiate SootMethod yourself, comparing them by == should be fine.

Yet in the code example above, if you call resolve() multiple time, I'm not
sure what will happen.
