Signal< NetworkMonitor > onNetworkStateChanged
 

Detailed Description

Network state change monitor.

When network change is detected, onNetworkStateChanged signal will be fired. Monitoring is run for the lifetime of the NetworkMonitor instance.

Note
Implementation of this class is platform dependent and not all supported platforms are supported:
  • OS X: CFNotificationCenterAddObserver
  • Linux: rtnetlink notifications

Network state change detection is not guaranteed to be precise and (zero or more) notifications are expected to be fired for the following events:

  • any network interface going up or down
  • IPv4 or IPv6 address changes on any of the interfaces
