* WebDAV-sync support for CalDAV backends.

*
|
|
* In order for backends to advertise support for WebDAV-sync, this interface

* must be implemented.
|
|
*
|
|
* Implementing this can result in a significant reduction of bandwidth and CPU
|
|
* time.
|
|
*
|
|
* For this to work, you _must_ return a {http://sabredav.org/ns}sync-token
|
|
* property from getCalendarsFromUser.

/**
|
|
* The getChanges method returns all the changes that have happened, since
|
|
* the specified syncToken in the specified calendar.
|
|
*
|
|
* This function should return an array, such as the following:
|
|
*
|
|
* [
|
|
* 'syncToken' => 'The current synctoken',
|
|
* 'added' => [
|
|
* 'new.txt',
|
|
* ],
|
|
* 'modified' => [
|
|
* 'modified.txt',
|
|
* ],
|
|
* 'deleted' => [
|
|
* 'foo.php.bak',
|
|
* 'old.txt'
|
|
* ]
|
|
* );
|
|
*
|
|
* The returned syncToken property should reflect the *current* syncToken
|
|
* of the calendar, as reported in the {http://sabredav.org/ns}sync-token
|
|
* property This is * needed here too, to ensure the operation is atomic.
|
|
*
|
|
* If the $syncToken argument is specified as null, this is an initial
|
|
* sync, and all members should be reported.
|
|
*
|
|
* The modified property is an array of nodenames that have changed since
|
|
* the last token.
|
|
*
|
|
* The deleted property is an array with nodenames, that have been deleted
|
|
* from collection.
|
|
*
|
|
* The $syncLevel argument is basically the 'depth' of the report. If it's
|
|
* 1, you only have to report changes that happened only directly in
|
|
* immediate descendants. If it's 2, it should also include changes from
|
|
* the nodes below the child collections. (grandchildren)
|
|
*
|
|
* The $limit argument allows a client to specify how many results should
|
|
* be returned at most. If the limit is not specified, it should be treated
|
|
* as infinite.
|
|
*
|
|
* If the limit (infinite or not) is higher than you're willing to return,
|
|
* you should throw a Sabre\DAV\Exception\TooMuchMatches() exception.
|
|
*
|
|
* If the syncToken is expired (due to data cleanup) or unknown, you must
|
|
* return null.
|
|
*
|
|
* The limit is 'suggestive'. You are free to ignore it.
