[antlr-interest] A challenging question

[Lorenz Pretterhofer]

Its not really the responsibility of a lexer or scanner to combine  
packets. This should be handled by your networking layer, either by  
hand if your using UDP or it will automatically occur when using TCP  
socket streams. Once you have a complete stream simply feed it into  
the lexer as you normally would.

When you think about it... The scanner can't really do anything with  
an incomplete packet anyway since its still incomplete;)

Cheers,
Lorenz
