◆ emitEnumerationCompleted()

void ndn::net::NetworkMonitorStub::emitEnumerationCompleted ( )

emit the onEnumerationCompleted signal

A real NetworkMonitor starts with an "enumerating" state, during which the initial information about network interfaces is collected from the OS. Upon discovering a network interface, it emits the onInterfaceAdded signal. When the initial enumerating completes, it emits the onEnumerationCompleted signal.

To simulate this procedure on a newly constructed MockNetworkMonitor, the caller should invoke addInterface once for each network interface that already exists, and then invoke signalEnumerationCompleted .
