Spezialisierungen

Beide benutzerdefinierte Spezialisierungen und Überladungen der std::swap Algorithmus erlaubt, aber die Überlastung sind in der Regel seit Spezialisierungen eines Funktions-Template bevorzugt sind nicht für Template-Klassen erlaubt. Library-Funktionen immer die vom Benutzer bereitgestellten Überlastungen beim Austausch, wenn sie durch das Argument-abhängigen lookup (nach Swappable Konzept) gefunden werden .

Original:

Both custom specializations and overloads of the std::swap algorithm are allowed, but the overloads are generally preferred since specializations of a function template aren't allowed for template classes. Library functions always use the user-provided overloads when swapping, if they are found by argument-dependent lookup (as per Swappable concept).
