Sustitución y sobrecarga

Las versiones 1-4) se declara implícitamente en cada unidad de traducción, incluso si el encabezado <new> no está incluido. Estas funciones son reemplazables': proporcionado por el usuario no miembro de función con la misma firma que sustituye a la versión implícita. A lo sumo una sustitución puede ser proporcionado para cada una de las cuatro funciones de desasignación implícitos. Además, el programa puede definir versiones de miembro de clase de estas funciones o definir funciones de asignación con firmas diferentes (excepto 5-6) no son reemplazables) .

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).

'En el ámbito global': para llamarlo, la firma de las funciones de asignación sobrecargado debe ser visible en el lugar de desafectación, excepto implícitamente declaradas funciones predeterminadas desasignación. Esta función de asignación se utiliza para todas las cancelaciones de asignación con los parámetros correspondientes en el programa actual

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

'En el ámbito local': el operator delete sobrecargado debe ser miembro público static function de la clase. Esta función desasignación se utilizará sólo para cancelaciones de asignación de esa clase particular .

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.

Durante la compilación, cada expresión delete mira el nombre de la función de cancelación de asignación que sean procedentes en primer lugar en el ámbito de la clase y después de que en el ámbito global. Puede ser instruidos para saltarse el primer paso. Tenga en cuenta, que según sobrecarga de reglas, las funciones desasignación declarados en el ámbito de clase oculta todas las funciones desasignación globales. Para obtener más información suprimir la expresión ver .

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 sobrecarga de reglas, any deallocation functions declared in class scope hides all global deallocation functions.
