lock

public void lock(org.alfresco.service.cmr.repository.NodeRef nodeRef,
                 LockType lockType)

Description copied from interface: LockService

Places a 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.

A lock made with this call will never expire.

Specified by:

lock in interface LockService

Parameters:

nodeRef - a reference to a node

lockType - the lock type

Description copied from interface: LockService

Places a persistent lock on a node.

The lock prevents any other user or process from comitting updates to the node until the lock is released.
