Detailed Description

Name component.

This type is immutable, except `decodeFrom()` method.

Constructor & Destructor Documentation

Component() [1/4]

ndnph::Component::Component ( )

explicitdefault

Component() [2/4]

ndnph::Component::Component ( Region &  region, uint16_t  type, size_t  length, const uint8_t *  value  )

inlineexplicit

Construct from T-L-V.

Component() [3/4]

ndnph::Component::Component ( Region &  region, size_t  length, const uint8_t *  value  )

inlineexplicit

Construct GenericNameComponent from L-V.

Component() [4/4]

ndnph::Component::Component ( uint8_t *  buf, size_t  bufLen, uint16_t  type, size_t  length, const uint8_t *  value, bool  writeFromBack = false  )

inlineexplicit

Construct from T-L-V into provided buffer.

Parameters

buf	buffer for writing TLV.
bufLen	size of buf; if insufficient, !component will be true.
type	TLV-TYPE
length	TLV-LENGTH
value	TLV-VALUE, may overlap with buf
writeFromBack	write TLV from back of provided buffer instead of from front.

Member Function Documentation

as()

template<typename Convention , typename... Arg>

auto ndnph::Component::as ( Arg &&...  arg ) const -> decltype(Convention::parse(*this, std::forward<Arg>(arg)...))

inline

constant()

static Component ndnph::Component::constant ( const uint8_t *  tlv, size_t  size  )

inlinestatic

Construct from const TLV buffer.

decodeFrom()

bool ndnph::Component::decodeFrom ( const Decoder::Tlv &  d )

inline

encodeTo()

void ndnph::Component::encodeTo ( Encoder &  encoder ) const

inline

from()

template<typename... Arg>

static Component ndnph::Component::from ( Region &  region, uint16_t  type, const Arg &...  arg  )

inlinestatic

Construct from TLV-TYPE, and several arguments to be encoded to TLV-VALUE.

Template Parameters

Arg	any Encodable type.

is()

template<typename Convention >

bool ndnph::Component::is ( ) const

inline

length()

size_t ndnph::Component::length ( ) const

inline

operator bool()

ndnph::Component::operator bool ( ) const

inlineexplicit

Return true if Component is valid.

parse() [1/4]

static Component ndnph::Component::parse ( Region &  region, const char *  uri  )

inlinestatic

Parse from URI.

Parameters

region	memory region; must have 8 + strlen(uri) available room.
uri	URI in canonical format; except that `8=` prefix of GenericNameComponent may be omitted.

Returns

component; it's valid if !component is false.

Note

This is a not-so-strict parser. It lets some invalid inputs slip through in exchange for smaller code size. Not recommended on untrusted input.

parse() [2/4]

static Component ndnph::Component::parse ( Region &  region, const char *  uri, size_t  uriLen  )

inlinestatic

parse() [3/4]

static Component ndnph::Component::parse ( uint8_t *  buf, size_t  bufLen, const char *  uri  )

inlinestatic

Parse from URI into provided buffer.

parse() [4/4]

static Component ndnph::Component::parse ( uint8_t *  buf, size_t  bufLen, const char *  uri, size_t  uriLen, bool  writeFromBack = false  )

inlinestatic
