@Auditable(parameters={"nodeRef","lockType"}) void lock(org.alfresco.service.cmr.repository.NodeRef nodeRef, LockType lockType) throws UnableToAquireLockException
The lock prevents any other user or process from comitting updates to the node until the lock is released.
The lock will be owned by the current user.
A lock made with this call will never expire.

persistent
lock on a node.
The lock prevents any other user or process from comitting updates to the node until the lock is released.
The lock will be owned by the current user.
If the time to expire is 0 then the lock will never expire. Otherwise the timeToExpire indicates the number of seconds before the lock expires. When a lock expires the lock is considered to have been released.
If the node is already locked and the user is the lock owner then the lock will be renewed with the passed timeToExpire.

- thrown if the node is locked by someone else. This is based on the lock status of the lock,

Do NOT use the returned information to determine the actual state of a lock,
use getLockStatus(NodeRef)
and other LockService methods for this purpose.
The returned data is intended for information purposes only, e.g. returning the timeout in a WebDAV response.
