com.viaoa.object.OALock

All Implemented Interfaces:

Serializable

public class OALock
extends Object
implements Serializable

OALock is used for setting and sharing locks on Objects.

Note: setting a lock does not restrict access to an Object, it only serves as a flag. It is currently the applications responsiblity to enforce rules based on a lock being set.

Note: this also works with OASync (Clients/Server) to create distributed locks.
