    Die std::allocator Klassen-Template ist die Standardeinstellung Allocator von allen Standard-Bibliothek Behälter verwendet, wenn kein Benutzer angegebenen allocator ist. Der Standardwert allocator staatenlos ist, das heißt, alle Instanzen der gegebenen allocator austauschbar sind, sind gleich und können Speicher von einem anderen Instanz desselben allocator Typ zugeordnet freigeben .
    Original:
    The std::allocator class template is the default Allocator used by all standard library containers if no user-specified allocator is provided. The default allocator is stateless, that is, all instances of the given allocator are interchangeable, compare equal and can deallocate memory allocated by any other instance of the same allocator type.

    All custom allocators also must be stateless. (bis C + +11)
    Custom allocators may contain state. Each container or another allocator-aware object stores an instance of the supplied allocator and controls allocator replacement through std::allocator_traits. (seit C++11)
