Member Function Documentation

crc()

uint32_t mcap::IWritable::crc

(

)

Returns the CRC32 of the uncompressed data.

end()

virtual void mcap::IWritable::end ( )

pure virtual

Called when the writer is finished writing data to the output MCAP file.

Implemented in mcap::IChunkWriter, mcap::ZStdWriter, mcap::LZ4Writer, mcap::BufferWriter, mcap::StreamWriter, and mcap::FileWriter.

handleWrite()

virtual void mcap::IWritable::handleWrite ( const std::byte *  data, uint64_t  size  )

protectedpure virtual

Implemented in mcap::ZStdWriter, mcap::LZ4Writer, mcap::BufferWriter, mcap::StreamWriter, and mcap::FileWriter.

resetCrc()

void mcap::IWritable::resetCrc

(

)

Resets the CRC32 calculation.

size()

virtual uint64_t mcap::IWritable::size ( ) const

pure virtual

Returns the current size of the file in bytes. This must be equal to the sum of all size parameters passed to write().

Implemented in mcap::IChunkWriter, mcap::ZStdWriter, mcap::LZ4Writer, mcap::BufferWriter, mcap::StreamWriter, and mcap::FileWriter.

write()

void mcap::IWritable::write	(	const std::byte *	data,
		uint64_t	size
	)

Called whenever the writer needs to write data to the output MCAP file.

Parameters

data	A pointer to the data to write.
size	Size of the data in bytes.
