Detailed Description

A Name::Component holds a read-only name component value.

Constructor & Destructor Documentation

ndn::Name::Component::Component	(	const std::vector< uint8_t > &	value,
		ndn_NameComponentType	type = `ndn_NameComponentType_GENERIC`,
		int	otherTypeCode = `-1`
	)

inline

Create a new Name::Component, copying the given value.

(To create an ImplicitSha256Digest component, use fromImplicitSha256Digest.) (To create a ParametersSha256Digest component, use fromParametersSha256Digest.)

Parameters

value	The value byte array, which is copied.
type	(optional) The component type as an int from the ndn_NameComponentType enum. If the name component type is not a recognized ndn_NameComponentType enum value, then set this to ndn_NameComponentType_OTHER_CODE and use the otherTypeCode parameter. If omitted, use ndn_NameComponentType_GENERIC.
otherTypeCode	(optional) If type is ndn_NameComponentType_OTHER_CODE, then this is the packet's unrecognized content type code, which must be non-negative.

ndn::Name::Component::Component	(	const uint8_t *	value,
		size_t	valueLength,
		ndn_NameComponentType	type = `ndn_NameComponentType_GENERIC`,
		int	otherTypeCode = `-1`
	)

inline

Create a new Name::Component, copying the given value.

(To create an ImplicitSha256Digest component, use fromImplicitSha256Digest.) (To create a ParametersSha256Digest component, use fromParametersSha256Digest.)

Parameters

value	A pointer to the value byte array, which is copied.
valueLength	The length of value.
type	(optional) The component type as an int from the ndn_NameComponentType enum. If the name component type is not a recognized ndn_NameComponentType enum value, then set this to ndn_NameComponentType_OTHER_CODE and use the otherTypeCode parameter. If omitted, use ndn_NameComponentType_GENERIC.
