Detailed Description

ProtobufTlv has static methods to encode and decode an Protobuf Message object as NDN-TLV.

The Protobuf tag value is used as the TLV type code. A Protobuf message is encoded/decoded as a nested TLV encoding. Protobuf types uint32, uint64 and enum are encoded/decoded as TLV nonNegativeInteger. (It is an error if an enum value is negative.) Protobuf types bytes and string are encoded/decoded as TLV bytes. The Protobuf type bool is encoded/decoded as a TLV boolean (a zero length value for True, omitted for False). Other Protobuf types are an error.

Protobuf has no "outer" message type, so you need to put your TLV message inside an outer "typeless" message.

static void ndn::ProtobufTlv::decode	(	google::protobuf::Message &	message,
		const uint8_t *	input,
		size_t	inputLength
	)

static

Decode the input as NDN-TLV and update the fields of the Protobuf Message object.

Parameters

message	The Protobuf Message object. This does not first clear the object.
input	A pointer to the input buffer to decode.
inputLength	The number of bytes in input.

static void ndn::ProtobufTlv::decode	(	google::protobuf::Message &	message,
		const std::vector< uint8_t > &	input
	)

inlinestatic

Decode the input as NDN-TLV and update the fields of the Protobuf Message object.

Parameters

message	The Protobuf Message object. This does not first clear the object.
input	The input byte array to be decoded.

static void ndn::ProtobufTlv::decode	(	google::protobuf::Message &	message,
		const Blob &	input
	)

inlinestatic

Decode the input as NDN-TLV and update the fields of the Protobuf Message object.

Parameters

message	The Protobuf Message object. This does not first clear the object.
input	The Blob with the input to be decoded.

static Blob ndn::ProtobufTlv::encode ( const google::protobuf::Message & message )

static

Encode the Protobuf Message object as NDN-TLV.

Parameters

message The Protobuf Message object. This calls message.CheckInitialized() to ensure that all required fields are present.

Returns: The encoded byte array as a Blob.
