[Bearbeiten] Notes

6-10)
Konstrukteure, die einen ersten Parameter vom Typ std::allocator_arg_t haben müssen eine zweite Argument alloc des Typs, der ein A Allocator ist. Diese Zuweisung wird verwendet, um Speicher für alle internen Datenstrukturen, dass die function könnte verwenden zu schaffen .
Original:
Constructors that have a first parameter of type std::allocator_arg_t must have a second argument alloc of type A that is an Allocator. This allocator is used to create memory for any internal data structures that the function might use.

5, 10) die Art F sollte CopyConstructible sein und das Objekt f sollte Callable sein. Die resultierende Funktion Objekt, das erstellt wird leer sein, wenn f ein NULL-Funktion Zeiger, ein NULL-Zeiger auf ein Element, oder wenn f ist ein std::function und !f == true. Das Argument f in die resultierende Funktion Objekt bewegt .
Original:
5, 10) The type F should be CopyConstructible and the object f should be Callable. The resulting function object that is created will be empty if f is a NULL function pointer, a NULL pointer to member, or if f is a std::function and !f == true. The argument f is moved into the resulting function object.
