Defines the interface for receiving information about changes in the state of the StreamLink connection, the data services available from the Liberator, and the DataSources that are normally connected to the Liberator.

You should implement this interface if your application needs to take particular actions when such state changes occur.

Your application should not call into StreamLink when the connection status changes; StreamLink manages the connection state and will recover the connection to the Liberator without your application intervening.

A trivial implementation would be as follows :

streamLink.addConnectionListener({
        onConnectionStatusChange: function(connectionStatusEvent) {
                console.log("Connection State : " + connectionStatusEvent.getConnectionState());
        },
        onServiceStatusChange: function(serviceStatusEvent) {
                console.log(serviceStatusEvent.getServiceName() + " is now " + serviceStatusEvent.getServiceStatus());
        },
        onSourceStatusChange: function(sourceStatusEvent) {
                console.log(sourceStatusEvent.getSourceName() + " is now " + sourceStatusEvent.getSourceStatus());
        },
        onStatisticsChange: function(statisticsEvent) {
                console.log("Latency : " + statisticsEvent.getAverageLatency());
        }
});
