void NUEDataManager::ParseOneEntry(const char* entry_start)
{
p_semi = strchr(entry_start,';');
assert(p_semi);
m_input =
antlr3NewAsciiStringInPlaceStream((pANTLR3_UINT8)entry_start,p_semi-entry_start+1,NULL);
m_lex = StepDataEntryLexerNew(m_input);
m_tokens = antlr3CommonTokenStreamSourceNew(ANTLR3_SIZE_HINT,
TOKENSOURCE(m_lex));
m_parser = StepDataEntryParserNew(m_tokens);
m_parser ->entry(m_parser,id);
m_parser->free(m_parser);
m_tokens->free(m_tokens);
m_lex->free(m_lex);
m_input->close(m_input);
}
the ParseOneEntry function will be called more than 1000000 times in most
cases.
So I am wondering if it is feasible to get this piece of code improved
further?
