Utilizza il a allocatore di allocare byte n*sizeof(Alloc::value_type) di archiviazione non inizializzato, chiamando a.allocate(n)
Original:

2)
Utilizza il a allocatore di allocare byte n*sizeof(Alloc::value_type) di archiviazione non inizializzato con il hint suggerimento memoria località. Chiamate a.allocate(n, hint) se possibile. Se non è possibile (ad esempio una non ha due argomenti funzione membro allocate ()), chiama a.allocate(n)
Original:
Uses the allocator a to allocate n*sizeof(Alloc::value_type) bytes of uninitialized storage with the memory locality hint hint. Calls a.allocate(n, hint) if possible. If not possible (e.g. a has no two-argument member function allocate()), calls a.allocate(n)
