`template< class Alloc > struct allocator_traits;`		(seit C++11)

Die allocator_traits Klassen-Template bietet die standardisierten Weg, um verschiedene Eigenschaften von Zuweiser zugreifen. Die Standard-Containern und anderen Standard-Bibliothek-Komponenten Zugriff Zuweiser durch diese Vorlage, die es ermöglicht, jede Klasse Typ als allocator verwenden, solange der Benutzer bereitgestellten Spezialisierung allocator_traits implementiert alle erforderlichen Funktionalität macht .

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.
