[Soot-list] Transformation capablilities of Soot

[Marc-André Laverdière-Papineau]

Hello Zeinab,

As a general thing, Soot can do whatever transformations you want. The 
only thing is that it is relatively tedious to do so programatically. 
That is the reason why Bernhard and I have used templates to generate 
Jimple.

Answering your questions
1. That looks like you want to do syntax-directed translation in order 
to determine the constant parts of that string concatenation. Am I right?

2. I have no idea what you want to ask...
3. Yes, very easy. You just have to use the PatchingChain API.
