Libère la mémoire. Ces fonctions sont appelées par répartition supprimer-expressions à libérer la mémoire après autodestruction objets dynamiques .

Original:

Deallocates storage. These allocation functions are called by supprimer-expressions to deallocate memory after destructing dynamic objects.

Remplacement de la surcharge

Les versions 1-4) sont implicitement déclaré dans chaque unité de traduction, même si l'en-tête <new> n'est pas inclus. Ces fonctions sont' remplaçable: un fourni par l'utilisateur non membre de fonction avec la même signature remplace la version implicite. Au plus un remplacement peut être fournie pour chacune des quatre fonctions de désallocation implicites. En outre, le programme peut définir les versions de membre de classe de ces fonctions ou de définir des fonctions de répartition avec des signatures différentes (sauf 5-6) ne sont pas remplaçables) .

Original:

The versions 1-4) are implicitly declared in each translation unit even if the <new> header is not included. These functions are replaceable: a user-provided non-member function with the same signature replaces the implicit version. At most one replacement may be provided for each of the four implicit deallocation functions. Also, program can define class member versions of these functions or define allocation functions with different signatures (except 5-6) are not replaceable).

'Dans la portée globale': pour l'appeler, la signature des fonctions d'allocation de surcharge doit être visible sur le lieu de désallocation, à l'exception des fonctions de désallocation implicitement déclarés par défaut. Cette fonction d'allocation sera utilisé pour toutes les libérations avec des paramètres correspondants dans le programme actuel

Original:

in the global scope: in order to call it, the signature of the overloaded allocation functions must be visible at the place of deallocation, except for implicitly declared default deallocation functions. This allocation function will be used for all deallocations with corresponding parameters in the current program

'Dans la portée locale': l'operator delete surchargée doit être statique fonction membre public de la classe. Cette fonction de désallocation sera utilisé uniquement pour désallocations de cette catégorie particulière .

Original:

in the local scope: the overloaded operator delete must be static public member function of the class. This deallocation function will be used only for deallocations of that particular class.

Lors de la compilation, chaque expression delete lève les yeux pour le nom de la fonction appropriée de désallocation d'abord dans le domaine de la classe et après que dans la portée globale. Il peut être chargé de sauter la première étape. Notez que selon surcharge règles, toutes les fonctions de désallocation déclarées dans la portée de classe se cache toutes les fonctions de désallocation mondiaux. Pour plus d'informations supprimer l'expression voir .

Original:

During compilation, each delete expression looks up for appropriate deallocation function's name firstly in the class scope and after that in the global scope. It can be instructed to skip the first step. Note, that as per surcharge règles, any deallocation functions declared in class scope hides all global deallocation functions. For more information see supprimer l'expression.
