virtual carto::fistreambuf< Extractor >::~fistreambuf ( )

virtual

Call sync(), delete the source streambuf if asked to do so in the constructor.

Member Function Documentation

extractor()

template<class Extractor >

Extractor & carto::fistreambuf< Extractor >::extractor ( )

inline

Actual filter.

Returns

the actual filter

seekoff()

template<class Extractor>

virtual pos_type carto::fistreambuf< Extractor >::seekoff ( off_type  , std::ios_base::seekdir  , std::ios_base::openmode  = std::ios_base::in|std::ios_base::out  )

protectedvirtual

setbuf()

template<class Extractor>

virtual std::streambuf* carto::fistreambuf< Extractor >::setbuf ( char *  p, std::streamsize  len  )

protectedvirtual

pass on to the source

Parameters

p
len

Returns

this

sync()

template<class Extractor>

virtual int carto::fistreambuf< Extractor >::sync ( )

protectedvirtual

underflow()

template<class Extractor>

virtual int carto::fistreambuf< Extractor >::underflow ( )

protectedvirtual

Get the first character of the pending sequence.

If the pending sequence is null then the function returns EOF to indicate failure.

Returns

the first character of the pending sequence
