Detailed Description

represents a Link object

Definition at line 32 of file link.hpp.

Constructor & Destructor Documentation

Link() [1/3]

ndn::Link::Link ( )

default

Create an empty Link object.

Note that in certain contexts that use Link::shared_from_this(), Link must be created using make_shared:

shared_ptr<Link> linkObject = make_shared<Link>();

Link() [2/3]

ndn::Link::Link ( const Block &  wire, bool  wantSort = true  )

explicit

Decode a Link object from a Block.

Parameters

wire	a TLV block
wantSort	if false, relative order among delegations is preserved

Note that in certain contexts that use Link::shared_from_this(), Link must be created using make_shared:

shared_ptr<Link> linkObject = make_shared<Link>(block);

Definition at line 35 of file link.cpp.

References wireDecode().

Link() [3/3]

ndn::Link::Link ( const Name &  name, std::initializer_list< Delegation >  dels = {}  )

explicit

Create a Link object with the given name and delegations.

Parameters

name	A reference to the name of the redirected namespace
dels	Delegations in payload

Note that in certain contexts that use Link::shared_from_this(), Link must be created using make_shared:

shared_ptr<Link> link = make_shared<Link>(name, dels);

Definition at line 40 of file link.cpp.

Member Function Documentation

wireDecode()

void ndn::Link::wireDecode	(	const Block &	wire,
		bool	wantSort = true
	)

Decode from the wire format.

Parameters

wire	a TLV block
wantSort	if false, relative order among delegations is preserved

Definition at line 67 of file link.cpp.

References ndn::tlv::ContentType_Link, ndn::Data::getContent(), ndn::Data::getContentType(), ndn::DelegationList::wireDecode(), and ndn::Data::wireDecode().

Referenced by Link().

getDelegationList()

const DelegationList& ndn::Link::getDelegationList ( ) const

inline

Get the delegations.

Definition at line 88 of file link.hpp.

setDelegationList()

void ndn::Link::setDelegationList

(

const DelegationList &

dels

)

Set the delegations.

Note

This is more efficient than multiple addDelegation and removeDelegation invocations.

Definition at line 79 of file link.cpp.

addDelegation()

void ndn::Link::addDelegation	(	uint32_t	preference,
		const Name &	name
	)

Add a delegation in the format of <Name, Preference>

Parameters

preference	The preference of the delegation to be added
name	The name of the delegation to be added

Note

If a delegation with name exists, its preference will be updated

Definition at line 86 of file link.cpp.

References ndn::DelegationList::INS_REPLACE, and ndn::DelegationList::insert().

removeDelegation()

bool ndn::Link::removeDelegation

(

const Name &

name

)

Remove a delegation whose name is name.

Parameters

name	The name of the delegation to be removed

Returns

true if delegation is removed, otherwise false

Definition at line 93 of file link.cpp.
