Interface ezcWebdavLockBackend

Interface to be implemented by backends which should be used with the lock plugin.

The lock plugin interacts with the backend only be sending ezcWebdavRequest requests, except for that it requires the backend to implement this interface.

The lock plugin will lock the backend as soon as it comes into action and release the lock, when all processing is done. The reason for the lock is to keep communication between the lock plugin and the backend atomic.
