Member Function Documentation

void rili::stream::BufferingReadable::consume ( std::size_t  size )

overridevirtual

consume remove given number of bytes from front of view

Parameters

size	number of bytes to remove

Implements rili::stream::Readable.

virtual std::exception_ptr rili::stream::BufferingReadable::fetch ( view::Default &  view )

protectedpure virtual

fetch used by BufferingReadable to retrieve data from sink. It should be implemented in way which insert to view data avaliable in sink so far

Parameters

view	is view which should be modified

Returns

operation error exception if occured.

Note

implementation is not abligated to insert any data to view if no data avaliable

std::exception_ptr rili::stream::BufferingReadable::pull ( std::size_t  count )

overridevirtual

pull used to pull from stream underlying sink at least given number of bytes

Parameters

count

number of bytes to retrieve from sink

Returns

error exception if occured

Note

implementation of this function do not should provide at least count number of bytes to view.

count equal to 0 means implementation should provide zero or more bytes to view and implementation should choose easiest amount to provide.

Implements rili::stream::Readable.

view::Base const& rili::stream::BufferingReadable::readableView ( ) const

overridevirtual

readableView used to access stream view

Returns

view
