Thanks for the response. I couldn't find where nextToken is set but I see
it now in antlr3lexer.c
antlr3LexerNew(ANTLR3_UINT32 sizeHint, pANTLR3_RECOGNIZER_SHARED_STATE
state)
{
...
/* Install the default nextToken() method, which may be overridden
* by generated code, or by anything else in fact.
*/
lexer->rec->state->tokSource->nextToken = nextToken;
...
}
