Constructor & Destructor Documentation

Writer()

roc::fec::Writer::Writer	(	const WriterConfig &	config,
		packet::FecScheme	fec_scheme,
		IBlockEncoder &	encoder,
		packet::IWriter &	writer,
		packet::IComposer &	source_composer,
		packet::IComposer &	repair_composer,
		packet::PacketFactory &	packet_factory,
		core::BufferFactory< uint8_t > &	buffer_factory,
		core::IAllocator &	allocator
	)

Initialize.

Parameters

• config contains FEC scheme parameters
• encoder is used to encode repair packets
• writer is used to write source and repair packets
• source_composer is used to format source packets
• repair_composer is used to format repair packets
• packet_factory is used to allocate repair packets
• buffer_factory is used to allocate buffers for repair packets
• allocator is used to initialize a packet array

Member Function Documentation

alive()

bool roc::fec::Writer::alive

(

)

const

Check if writer is still working.

resize()

bool roc::fec::Writer::resize	(	size_t	sblen,
		size_t	rblen
	)

Set number of source packets per block.

valid()

bool roc::fec::Writer::valid

(

)

const

Check if object is successfully constructed.

write()

virtual void roc::fec::Writer::write ( const packet::PacketPtr &  )

virtual

Write packet.

Remarks

• writes the given source packet to the output writer
• generates repair packets and also writes them to the output writer

Implements roc::packet::IWriter.
