Shared Object Events

Shared Object Events

The SharedObject included in the SDK is an event emitter that has a basic API to subscribing and unsubscribing to events either by name or by wildcard.

To subscribe to all events from a shared object:

function handleSharedObjectEvent (event) {
  // The name of the event:
  var type = event.type;
  // The name associated with the shared object instance:
  var name = event.name;
  // Optional data releated to the event (not available on all events):
  var data = event.data;

var so = new red5prosdk.Red5ProSharedObject();
so.on('*', handleSharedObjectEvent);

The * type assignment is considered a "Wildcard" subscription - all events being issued by the shared object instance will invoke the assign event handler.

To unsubscribe to all events from a shared object after assinging an event handler:

so.off('*', handleSharedObjectEvent);

The following sections of this document describe the event types that can also be listened to directly, instead of using the * wildcard.
