      • NetworkCheckThread

        public NetworkCheckThread​(java.util.concurrent.atomic.AtomicBoolean showNetStatus,
                          java.util.concurrent.atomic.AtomicBoolean isNetAvailable,
                          java.lang.Long interval)
        Constructs a new instance of this class. Once started, the thread checks network availability at a specified frequency and stores the result in an atomic variable specified to the constructor. The thread terminates when it's interrupted or when a specified boolean atomic variable has the value false.
        Parameters:
        showNetStatus - a reference to an atomic variable indicating whether the thread should continue running. This variable is tested prior to each network check. The thread terminates when it becomes false.
        isNetAvailable - a reference to an atomic variable in which to write the status of the network check.
        interval - the interval at which to perform the network check, or null if the default interval of one second is to be used.
