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.

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

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
