std::basic_ostream_sentry
std::basic_ostream< _CharT, _Traits >::sentry(3) Library Functions Manual std::basic_ostream< _CharT, _Traits >::sentry(3) NAME
std::basic_ostream< _CharT, _Traits >::sentry - SYNOPSIS
Public Member Functions sentry (basic_ostream< _CharT, _Traits > &__os) ~sentry () operator bool () const Detailed Description template<typename _CharT, typename _Traits = char_traits<_CharT>>class std::basic_ostream< _CharT, _Traits >::sentry Performs setup work for output streams. Objects of this class are created before all of the standard inserters are run. It is responsible for exception-safe prefix and suffix operations. Definition at line 400 of file ostream. Constructor &; Destructor Documentation template<typename _CharT, typename _Traits> std::basic_ostream< _CharT, _Traits >::sentry::sentry (basic_ostream< _CharT, _Traits > &__os) [explicit] The constructor performs preparatory work. Parameters: __os The output stream to guard. If the stream state is good (__os.good() is true), then if the stream is tied to another output stream, is.tie()->flush() is called to synchronize the output sequences. If the stream state is still good, then the sentry state becomes true (okay). Definition at line 47 of file ostream.tcc. References std::ios_base::failbit, std::basic_ios< _CharT, _Traits >::good(), std::basic_ios< _CharT, _Traits >::setstate(), and std::basic_ios< _CharT, _Traits >::tie(). template<typename _CharT, typename _Traits = char_traits<_CharT>> std::basic_ostream< _CharT, _Traits >::sentry::~sentry () [inline] Possibly flushes the stream. If ios_base::unitbuf is set in os.flags(), and std::uncaught_exception() is true, the sentry destructor calls flush() on the output stream. Definition at line 428 of file ostream. References std::ios_base::badbit, std::uncaught_exception(), and std::ios_base::unitbuf. Member Function Documentation template<typename _CharT, typename _Traits = char_traits<_CharT>> std::basic_ostream< _CharT, _Traits >::sentry::operator bool () const [inline], [explicit] Quick status checking. Returns: The sentry state. For ease of use, sentries may be converted to booleans. The return value is that of the sentry state (true == okay). Definition at line 449 of file ostream.
