allocator_traitsクラステンプレートは、アロケータのさまざまなプロパティにアクセスするための標準化された方法を提供します。標準コンテナとそれが可能allocator_traitsのユーザー提供の分業限り、アロケータとして任意のクラス型を使用するようになって、このテンプレートを介して他の標準ライブラリコンポーネントへのアクセスアロケータは、すべての必要な機能を実装しています.

Original:

The allocator_traits class template provides the standardized way to access various properties of allocators. The standard containers and other standard library components access allocators through this template, which makes it possible to use any class type as an allocator, as long as the user-provided specialization of allocator_traits implements all required functionality.
