Detailed Description

template<typename Source, std::streamsize source_eof = -1>
class staticlib::io::unbuffered_istreambuf< Source, source_eof >

Unbuffered implementation of input streambuf, wraps Source reference (in terms of Boost.Iostreams).

Should be used directly, must NOT be used wrapped into std::istream.

Constructor & Destructor Documentation

template<typename Source, std::streamsize source_eof = -1>

staticlib::io::unbuffered_istreambuf< Source, source_eof >::unbuffered_istreambuf ( Source &&  source )

inlineexplicit

Constructor, created source wrapper will own specified source.

Parameters

source

Source instance (in terms of Boost.Iostreams)

template<typename Source, std::streamsize source_eof = -1>

staticlib::io::unbuffered_istreambuf< Source, source_eof >::unbuffered_istreambuf

(

const unbuffered_istreambuf< Source, source_eof > &

)

Deleted copy constructor.

template<typename Source, std::streamsize source_eof = -1>

staticlib::io::unbuffered_istreambuf< Source, source_eof >::unbuffered_istreambuf ( unbuffered_istreambuf< Source, source_eof > &&  other )

inline

Move constructor.

Member Function Documentation

template<typename Source, std::streamsize source_eof = -1>

Source& staticlib::io::unbuffered_istreambuf< Source, source_eof >::get_source ( )

inline

Underlying source accessor.

Returns

underlying source reference

template<typename Source, std::streamsize source_eof = -1>

unbuffered_istreambuf& staticlib::io::unbuffered_istreambuf< Source, source_eof >::operator=

(

const unbuffered_istreambuf< Source, source_eof > &

)

Deleted copy assignment operator.

template<typename Source, std::streamsize source_eof = -1>

unbuffered_istreambuf& staticlib::io::unbuffered_istreambuf< Source, source_eof >::operator= ( unbuffered_istreambuf< Source, source_eof > &&  other )

inline

Move assignment operator.

template<typename Source, std::streamsize source_eof = -1>

virtual int staticlib::io::unbuffered_istreambuf< Source, source_eof >::uflow ( )

inlineoverridevirtual

Compatibility method to mimic expected EOF reporting of this streambuf.

Return 'std::char_traits<char>::eof()' if the Source was exhausted, throws 'UtilsException' otherwise.

Reimplemented from staticlib::io::detail::unbuffered_streambuf_base.

template<typename Source, std::streamsize source_eof = -1>

virtual std::streamsize staticlib::io::unbuffered_istreambuf< Source, source_eof >::xsgetn ( char *  s, std::streamsize  count  )

inlineoverrideprotectedvirtual

Reads count characters from the input sequence and stores them into a character array pointed to by s On Source EOF returns 0 and sets this streambuf state to 'exhausted'.

Parameters

s	destination buffer
count	number of characters to read

Reimplemented from staticlib::io::detail::unbuffered_streambuf_base.
