[Soot-list] about SourceLnPosTag

[Jauhar Ali]

We have just started using Soot in our research project which deals with 
visualizing data structures (dynamically) in Java. Our approach is to 
instrument Java code, so that the visualization component get info about 
each statement via the instrumented code. The instrumented code is 
responsible to pass the info about each statement (say in Jimple) and 
the exact location in the source code so that it can be visualized 
properly. By setting the KeepLineNumber flag on and taking input from 
Java source files, we are able to get the source line number for each 
Jimple statement. But we could not get the column positions because the 
Jimple statements have not got the SourceLnPosTag attached to them. Is 
there any extra switch which needs to be on to get the SourceLnPosTag 
attached to Jimple statements?
Thanks,
Jauhar
