示例1:

getText (pANTLR3_LEXER lexer)
{
if (lexer->rec->state->text)
{
return lexer->rec->state->text;
}
return lexer->input->substr(
lexer->input,
lexer->rec->state->tokenStartCharIndex,
lexer->getCharIndex(lexer) - lexer->input->charByteSize
);

* we are in code that we want to run as fast as possible

* trying to emit a new token.
*/

* get added automatically, such as the input stream it is associated with
