Detailed Description

A unicast Transport that uses raw Ethernet II frames.

Constructor & Destructor Documentation

◆ UnicastEthernetTransport()

Member Function Documentation

◆ canChangePersistencyToImpl()

bool nfd::face::UnicastEthernetTransport::canChangePersistencyToImpl ( ndn::nfd::FacePersistency  newPersistency) const
finalprotectedvirtual

invoked by canChangePersistencyTo to perform the check

Base class implementation returns false.

Parameters
newPersistencythe new persistency, guaranteed to be different from current persistency

Reimplemented from nfd::face::Transport.

Definition at line 78 of file unicast-ethernet-transport.cpp.

◆ afterChangePersistency()

void nfd::face::UnicastEthernetTransport::afterChangePersistency ( ndn::nfd::FacePersistency  oldPersistency)
finalprotectedvirtual

invoked after the persistency has been changed

The base class implementation does nothing. When overridden in a subclass, the function should update internal states after persistency setting has been changed.

Reimplemented from nfd::face::Transport.

Definition at line 84 of file unicast-ethernet-transport.cpp.
