<h2>概要</h2>
<p><code>allocator_traits</code>は、アロケータクラスの機能に間接的にアクセスするためのインタフェースを提供するクラスである。</p>
<h2>備考</h2>
<p>このクラスはC++11から導入され、メモリアロケータを扱うクラス(たとえばコンテナ)は、アロケータクラスの機能に直接アクセスする従来の仕様から、<code>allocator_traits</code>を介してアロケータにアクセスするように変更された。</p>
<p><code>allocator_traits</code>はアロケータに必要な機能の多くに対してデフォルト実装を用意しているため、この変更により、ユーザーが自作アロケータを作るのが容易になった。</p>
