* - 値のセット，追加，挿入等で printf() の記法が使える API
* - 要素単位のアクセス
* - 基本的な文字・文字列の検索
* - 左右の空白，改行文字の除去
* - 文字列のデリミタでの分割
* - シェル風の文字列マッチ
* - 正規表現による検索，置換，後方参照情報の取得
* - 要素文字列に対するポインタ配列の取得
* * @note 内部のバッファは 1Gbyte 未満では 2^n 単位で確保されるため，かなり * 頻繁な更新処理に対しても十分なパフォーマンスが得られるでしょう． * @author Chisato YAMAUCHI * @date 2013-04-01 00:00:00 */ class tarray_tstring { public: /* constructor and destructor */ tarray_tstring();
