swap(std::basic_filebuf) (C++11)

 

std::basic_filebuf& operator=(std::basic_filebuf&& rhs );		(dal C++11)
std::basic_filebuf& operator=(conststd::basic_filebuf& rhs )= delete;

1)

Prima chiama close() per chiudere il file associato, poi si sposta il contenuto di rhs in *this: la put e get buffer, il file associato, il locale, il openMode, la bandiera is_open, e qualsiasi altro stato. Dopo lo spostamento, rhs non è associato a un file e rhs.is_open()==false.

Original:

First calls close() to close the associated file, then moves the contents of rhs into *this: the put and get buffers, the associated file, the locale, the openmode, the is_open flag, and any other state. After the move, rhs is not associated with a file and rhs.is_open()==false.
