Detailed Description

Buffer output stream.

Constructor & Destructor Documentation

gf::BufferOutputStream::BufferOutputStream ( std::vector< uint8_t > * bytes )

Constructor.

Parameters

bytes The supplied external bytes to be written

std::vector< uint8_t > * gf::BufferOutputStream::getBytes ( )

inline

Get the underlying bytes.

virtual std::size_t gf::BufferOutputStream::getWrittenBytesCount ( ) const

overridevirtual

Get the number of bytes already written.

This function returns the number of bytes actually written i.e. it does not take into account possible bytes that have not been flushed yet.

virtual std::size_t gf::BufferOutputStream::write ( Span< const uint8_t > buffer )

overridevirtual

Write data to the stream.

Parameters

buffer The buffer to copy to the stream
