[antlr-interest] find and go back to same place.

[Andrei Timisescu]

I think I experienced something like this when I implemented a SIP/MGCP parser.
 
Try saving the lexer context with

int posInLexer = ((antlr::CharScanner*)(selector->getCurrentStream()))->mark();

and restore it when you want with

((antlr::CharScanner*)(selector->getCurrentStream()))->rewind(posInLexer);

See if the parser token stack has a valid state.

Hi !!!
In the middle of file parsing,I need to search a word(let's say $ROLE) in
the same file,store the value of that word and again start the parsing from
the same location where I had left earlier.
Actually, right now after searching $ROLE, parsing gets start from this
word($ROLE) onwards.Thus skips some lines of file.
How can I go back to the same place which I had left for searching keyword?
I hope someone will definitely help me.

Nijesh
