ActivityWatcher
@3dverse/livelink / ActivityWatcher
Class: ActivityWatcher
Defined in: node_modules/@3dverse/livelink.core/dist/sources/ActivityWatcher.d.ts:25
Watch activity on the gateway.
Activity is defined as any message sent to the gateway that is not a heartbeat.
Internally the activity watcher uses two timeouts:
- Inactivity warning: the time in seconds after which the
on-warningevent is dispatched. - Inactivity timeout: the time in seconds after which the
on-timeoutevent is dispatched.
The on-timeout event automatically triggers the disconnection from the gateway.
The application should listen to these events and act accordingly.
Usually, when the on-warning event is dispatched, the application should display a warning to the user.
It is up to the application to decide what can be qualified as activity.
For example, the application could consider the user moving the mouse as activity. In this case, the application
would listen to the "mousemove" event and reset the activity watcher whenever the mouse is moved calling
the ActivityWatcher.reset method.
When the on-timeout event is dispatched, there is no way to recover the connection. The application should
display an error message to the user.
