# Interface UserSessionListener

All Superinterfaces:
  `EventListener`, `SystemEventListener`

    public interface UserSessionListener
    extends SystemEventListener

Implementors receive notification when the user session changes.

This notification is useful for discontinuing a costly animation, or indicating that the user is no longer present on a network service.

Some systems may provide a reason of the user session change.
