virtual std::ostream& dtn::data::Block::serialize	(	std::ostream &	stream,
		size_t &	length
	)		const [pure virtual]

Serialize the derived block payload.

Parameters:

stream

A output stream to serialize into.

Returns:

The same reference as given with the stream parameter.

Implemented in dtn::data::AgeBlock, dtn::data::CompressedPayloadBlock, dtn::data::CustodySignalBlock, dtn::data::ExtensionBlock, dtn::data::PayloadBlock, dtn::data::StatusReportBlock, dtn::security::SecurityBlock, and StreamBlock.

std::ostream & dtn::data::Block::serialize_strict	(	std::ostream &	stream,
		size_t &	length
	)		const [protected, virtual]

Serialize the block in a strict way. Dynamic fields are set to the last deserialized value.

Parameters:

stream

the stream to be written into

Returns:

the same stream as the parameter for chaining
