Subject Re: Using ReverseMappingTool.run(...) to generate Java strings?
Date Sat, 07 Dec 2013 17:54:30 GMT
Have you tried to extend the ReverseMappingTool so that you can intercept
the generated code rather than write it to a file? ... I'm not sure
how feasible this might be as I'm writing from my phone.
