Detailed Description

Compressed output stream.

Constructor & Destructor Documentation

gf::CompressedOutputStream::CompressedOutputStream ( OutputStream & compressed )

explicit

Constructor.

Parameters

compressed A stream to store the compressed data

gf::CompressedOutputStream::~CompressedOutputStream ( )

Destructor.

std::size_t gf::CompressedOutputStream::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.

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

overridevirtual

Write data to the stream.

Parameters

buffer The buffer to copy to the stream
