Detailed Description

Class ilWebDAVLockBackend.

Implementation for WebDAV locking mechanism. Extends the LockBackend from sabreDAV and saves sabreDAV locks as ILIAS locks to DB and returns ILIAS locks in DB as sabreDAV locks. Also removes existing locks

Member Function Documentation

◆ getLocks()

ilWebDAVLockBackend::getLocks	(	$uri,
		$returnChildLocks
	)

This function returns all locks and child locks as SabreDAV lock objects It is needed for sabreDAV to see if there are any locks.

Returns a list of Sabre objects.This method should return all the locks for a particular uri, including locks that might be set on a parent uri.If returnChildLocks is set to true, this method should also look for any locks in the subtree of the uri for locks.

Parameters

string	$uri
bool	$returnChildLocks

Returns: array

See also: ::getLocks()

Implements Sabre\DAV\Locks\Backend\BackendInterface.
