[antlr-interest] Lexer

[Henry Butowsky]

Hi Guys,
   Im using Antlr 2.7.5 in C++.
   How do I get the lexer to read from a string rather than a file ?
   I've been looking at CharScanner class but nothing immediatly springs 
to mind. Im a bit of a newbie when it comes to C++ things

  I use the following code to initialize the lexer & parser.

char *filename;
ifstream *in;

ncoLexer lexer(*in);
lexer.setFilename(filename);
 
        ncoParser parser(lexer);
parser.setFilename(filename);
