Detailed Description

Serializes a bundle in mutable canonical form into a given stream. In mutable canonical form all SDNVs are unpacked to 8 byte values and all EID references are filled with the EID they point to. Every number is written in network byte order. Only payload related blocks are serialized. These are the payload block, the PayloadIntegrityBlock and the PayloadConfidentialBlock.

Constructor & Destructor Documentation

dtn::security::MutualSerializer::MutualSerializer	(	std::ostream &	stream,
		const dtn::data::Block *	ignore = NULL

Creates a MutualSerializer which will stream into stream

Parameters:

stream

the stream in which the mutable canonical form will be written into

Member Function Documentation

size_t dtn::security::MutualSerializer::getLength

(

const dtn::data::Bundle &

obj

)

[virtual]

Not implemented. This is only required by the interface.

Reimplemented from dtn::data::DefaultSerializer.

Definition at line 126 of file MutualSerializer.cpp.

Referenced by operator<<().

size_t dtn::security::MutualSerializer::getLength

(

const dtn::data::PrimaryBlock &

obj

)

const [virtual]

Returns the length of the primary block in mutable canonical form.

Parameters:

obj	the primary block, of which the length shall be calculated

Returns:

the length of the primary block

Reimplemented from dtn::data::DefaultSerializer.

size_t dtn::security::MutualSerializer::getLength

(

const dtn::data::Block &

obj

)

const [virtual]

Returns the length of the block in mutable canonical form.

Parameters:

obj	the block, of which the length shall be calculated

Returns:

the length of the block

dtn::data::Serializer & dtn::security::MutualSerializer::operator<<

(

const dtn::data::PrimaryBlock &

obj

)

[virtual]

Serializes the primary block in mutable canonical form. The usual rules for mutable canonicalisation (network byte order, unpacked SDNV, full EIDs instead of references) apply here and some bits of the flags are set to zero during this operation.

Returns:

a reference to this instance
