[antlr-interest] Getting input from an alternate source (sockets)

[Monty Zukowski]

This is actually an interesting problem.  java.regex.Matcher has two
methods specifically to address whether more input would change the
last match: hitEnd() and requireEnd().  See
http://java.sun.com/j2se/1.5.0/docs/api/java/util/regex/Matcher.html#hitEnd()

I haven't totally digested the semantics of the two, but inspection of
the source would help in that effort.  Ter, I think something similar
to this may be possible to incorporate into your DFAs.  For this
situation it would be extremely useful to have something similar, and
I bet it would be an interesting enhancement to your algorithm.
