Deprecated.

A specific lock method for the PessimisticLockInterceptor. It should *not* be used anywhere else as it has very peculiar and specific characteristics.

For implementations of this LockManager interface that are not intended for use with the PessimisticLockInterceptor, it is okay not to implement this method (a no-op).

Parameters:

fqn - Fqn to lock

lockType - Type of lock to acquire

ctx - invocation context

createIfNotExists - if true, nodes will be created if they do not exist.

zeroLockTimeout - if true uses 0 as a lock acquisition timeout

acquireWriteLockOnParent - if true, write locks are acquired on parent nodes when child nodes need write locks.

reverseRemoveCheck - if true, nodes that have been marked as removed in the current transaction may be reversed.

createdNodes - a list to which nodes created in this method may be added.

skipNotification - if true, node creation notifications are suppressed.

Returns:

true if successful; false otherwise.

Throws:

InterruptedException - if interrupted
