パーサー用の「文字列スプリッター」を書いていますが、char と wchar_t の両方を使用できるようにしたいと考えています。私は次の方法を持っています：
static void tokenize(const basic_string<T> &, vector<CToken> &);
そして、解析するワイド文字列を指定したいと思います:
vector<CToken> tTokens;
CTokenizer<wstring>::tokenize(L"if(i == 0) { print i + 2; } else { return; }", tTokens);
私も試しました：
vector<CToken> tTokens;
const wstring sCode = L"if(i == 0) { print i + 2; } else { return; }";
CTokenizer<wstring>::tokenize(sCode, tTokens);
したがって、テンプレートについて理解できないことがあると思います。どうすればいいですか？
ご協力いただきありがとうございます ！

parser.cpp のコードは上記のものです。
vector<CToken> tTokens;
const wstring sCode = L"if(i == 0) { print i + 2; } else { return; }";
CTokenizer<wstring>::tokenize(sCode, tTokens);
