Interface Sabre\CalDAV\Backend\SubscriptionSupport

Returns a list of subscriptions for a principal.

Every subscription is an array with the following keys:

• id, a unique id that will be used by other functions to modify the subscription. This can be the same as the uri or a database key.
• uri. This is just the 'base uri' or 'filename' of the subscription.
• principaluri. The owner of the subscription. Almost always the same as principalUri passed to this method.

Furthermore, all the subscription info must be returned too:

1. {DAV:}displayname
2. {http://apple.com/ns/ical/}refreshrate
3. {http://calendarserver.org/ns/}subscribed-strip-todos (omit if todos should not be stripped).
4. {http://calendarserver.org/ns/}subscribed-strip-alarms (omit if alarms should not be stripped).
5. {http://calendarserver.org/ns/}subscribed-strip-attachments (omit if attachments should not be stripped).
6. {http://calendarserver.org/ns/}source (Must be a Sabre\DAV\Property\Href).
7. {http://apple.com/ns/ical/}calendar-color
8. {http://apple.com/ns/ical/}calendar-order
9. {urn:ietf:params:xml:ns:caldav}supported-calendar-component-set (should just be an instance of Sabre\CalDAV\Property\SupportedCalendarComponentSet, with a bunch of default components).

Creates a new subscription for a principal.

If the creation was a success, an id must be returned that can be used to reference this subscription in other methods, such as updateSubscription.

Updates a subscription.

The list of mutations is stored in a Sabre\DAV\PropPatch object. To do the actual updates, you must tell this object which properties you're going to process with the handle() method.

Calling the handle method is like telling the PropPatch object "I promise I can handle updating this property".

Read the PropPatch documentation for more info and examples.

Deletes a subscription.
