public final class ClientLockReferenceIdGenerator
extends Object
This class generates unique (per client) incrementing reference ID which is used during locking related requests.
The server side uses this ID to match if any previous request with the same ID was issued and shall not re-do the lock related
operation but it shall just return the previous result. Hence, this ID identifies the outstanding request sent to the server
side for locking operations. Similarly, if the client resends the request to the server for some reason it will use the same
reference ID to make sure that the operation is not executed more than once at the server side.
