Network interface monitor.
NetworkMonitor(boost::asio::io_service &io)
Construct instance, request enumeration of all network interfaces, and start monitoring for network s...
util::Signal< NetworkMonitorImpl > & onEnumerationCompleted
Fires when the enumeration of all network interfaces on the system is complete.
uint32_t getCapabilities() const
Returns a bitwise OR'ed set of Capability flags supported on the current platform.
util::Signal< NetworkMonitorImpl, shared_ptr< const NetworkInterface > > & onInterfaceAdded
Fires whenever a new interface is detected on the system.
std::vector< shared_ptr< const NetworkInterface > > listNetworkInterfaces() const
Lists all network interfaces currently available on the system.
shared_ptr< const NetworkInterface > getNetworkInterface(const std::string &ifname) const
Returns the NetworkInterface with the given name, or nullptr if it does not exist.
util::Signal< NetworkMonitorImpl, shared_ptr< const NetworkInterface > > & onInterfaceRemoved
Fires whenever an interface disappears from the system.
