[Soot-list] soot introduced locals

[Arnab De]

Hi,
Is there any generic way to find out whether a local is introduced by
soot or whether it came from the source code? I observed that soot
introduced temporaries have names starting with $. Is it always the
case? Moreover, if local splitter is on, is it guaranteed that every
soot introduced temporary will have at most one assignment statement?

Thanks in advance,
Arnab
