public void shutdown()
Registry
Unsubscribe all local devices and GENA subscriptions.
public void pause()
Registry
When paused, the registry will no longer remove expired remote devices if their discovery announcements stop for some reason (device was turned off). Your local control point will now see potentially unavailable remote devices. Outbound GENA subscriptions from your local control point to remote services will not be renewed automatically anymore, a remote service might drop your subscriptions if you don't resume maintenance within the subscription's expiration timeout.
Local devices and services will not be announced periodically anymore to remote control points, only when they are manually added are removed from the registry. The registry will also no longer remove expired inbound GENA subscriptions to local service from remote control points, if that control point for some reason stops sending subscription renewal messages.
public void resume()
Registry
A local control point has to handle the following situations when resuming registry maintenance:
A remote device registration might have expired. This is the case when the remote device stopped sending announcements while the registry was paused (maybe because the device was switched off) and the registry was paused longer than the device advertisement's maximum age. The registry will not know if the device is still available when it resumes maintenance. However, it will simply assume that the remote device is still available and restart its expiration check cycle. That means a device will finally be removed from the registry, if no further announcements from the device are received, when the maximum age of the device has elapsed after the registry resumed operation.
Secondly, a remote device registration might not have expired but some of your
outbound GENA subscriptions to its services have not been renewed within the expected renewal
period. Therefore your outbound subscriptions might be invalid, because the remote
service can drop subscriptions when you don't renew them. On resume, the registry
will attempt to send renewals for all outbound GENA subscriptions that require
renewal, on devices that still haven't expired. If renewal fails, your subscription will
end with CancelReason.RENEWAL_FAILED
. Although
you then might conclude that the remote device is no longer available, a GENA renewal
can also fail for other reasons. The remote device will be kept and maintained in the
registry until it announces itself or it expires, even after a failed GENA renewal.
If you are providing local devices and services, resuming registry maintenance has the following effects:
Local devices and their services are announced again immediately if the registry has been paused for longer than half of the device's maximum age. Remote control points will either see this as a new device advertisement (if they have dropped your device while you paused maintenance) or as a regular update if you didn't pause longer than the device's maximum age/expiration timeout.
Inbound GENA subscriptions to your local services are active, even in paused state - remote control points should continue renewing the subscription. If a remote control point stopped renewing a subscription without unsubscribing (hard power off), an outdated inbound subscription will be detected when you resume maintenance. This subscription will be cleaned up immediately on resume.
