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

newPersistency the new persistency, guaranteed to be different from current persistency

Reimplemented from nfd::face::Transport.

Definition at line 71 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 77 of file unicast-ethernet-transport.cpp.
