Detailed Description

A TlvEncoder extends a C ndn_TlvEncoder struct and wraps related functions.

Constructor & Destructor Documentation

ndn::TlvEncoder::TlvEncoder ( size_t initialLength = 16 )

inline

Initialize the base ndn_TlvEncoder struct with the initialLength.

Use simpleRealloc.

Parameters

initialLength The initial size of the output. If omitted, use 16.

Blob ndn::TlvEncoder::finish ( )

inline

Resize the output vector to the correct encoding length, transfer the bytes to a Blob and return the Blob.

This clear the internal pointer to the output vector, and further calls to write to it will throw an exception.

Parameters

size	The final size of the allocated vector.

void ndn::TlvEncoder::writeNestedTlv	(	unsigned int	type,
		void()(const void context, TlvEncoder &encoder)	writeValue,
		const void *	context,
		bool	omitZeroLength = `false`
	)

inline

Call writeNestedTlv so that it calls writeValue(context, *this).

Parameters

type	The TLV type for writeNestedTlv.
writeValue	The callback to write the TLV value. This calls writeValue(context, *this).
context	The context to pass to writeValue.
omitZeroLength	The omitZeroLength flag for writeNestedTlv.

void ndn::TlvEncoder::writeRawStringTlv	(	unsigned int	type,
		const std::string &	value
	)

inline

Call writeBlobTlv using the raw string bytes.

Parameters

type	The type of the TLV.
value	The raw string.
