示例1:
static pANTLR3_STRING getText (pANTLR3_COMMON_TOKEN token)
{
if (token->text != NULL)
{
return token->text;
}
if (token->type == ANTLR3_TOKEN_EOF)
{
token->setText8(token, (pANTLR3_UINT8)"<EOF>");
return token->text;
}
if (token->input != NULL)
{
return token->input->substr( token->input,
token->getStartIndex(token),
token->getStopIndex(token));
}
/* Nothing to return
*/
return NULL;
}示例2: token_text
string mcmt_state::token_text(pANTLR3_COMMON_TOKEN token) {
ANTLR3_MARKER start = token->getStartIndex(token);
size_t size = token->getStopIndex(token) - start + 1;
return string((const char*) start, size);
