[Soot-list] Map from source line numbers to class file line numbers

[Manas Thakur]

I meant the byte code offset, and found that what I need is the BytecodeOffsetTag! Thanks for pushing me to think again.

When I am taking the line number tag, I am still getting ’10’ even though I am giving my class file as input to Soot, i.e., the line number of the variable in the java file. Is there some way through which I can get ’20’?
