Detailed Description

Provides support for an underlying protocol.

FaceSystem

A protocol factory provides support for an underlying protocol and owns Channel objects. It can process a subsection of face_system config section and create channels and multicast faces accordingly.

unique_ptr< ProtocolFactory > nfd::face::ProtocolFactory::create ( const std::string &  id,
const CtorParams params 
)
static

Create a protocol factory instance.

Return values
nullptrif a factory with the given id is not registered

Definition at line 42 of file protocol-factory.cpp.

void nfd::face::ProtocolFactory::createFace ( const CreateFaceRequest req,
const FaceCreatedCallback onCreated,
const FaceCreationFailedCallback onFailure 
)

Create a unicast face.

Parameters
reqrequest object containing the face creation parameters
onCreatedcallback if face creation succeeds or face already exists; the settings of an existing face are not updated if they differ from the request
onFailurecallback if face creation fails

Definition at line 86 of file protocol-factory.cpp.

shared_ptr< Face > nfd::face::ProtocolFactory::createNetdevBoundFace ( const FaceUri &  remote,
const shared_ptr< const ndn::net::NetworkInterface > &  netdev 
)

Create a netdev-bound face.

Parameters
remoteremote FaceUri, must be canonical
netdevlocal network interface
Returns
new face
Exceptions
Errorcannot create a face using specified arguments
Note
The caller must ensure there is no existing netdev-bound face with same remote FaceUri on the same local network interface.
