org.jboss.cache.optimistic.WorkspaceNode
Represents a type of {@link org.jboss.cache.Node} that is to be copied into a {@link TransactionWorkspace} for optimistically lockednodes. Adds versioning and dirty flags over conventional Nodes.
Typically used when the cache mode configured is {@link org.jboss.cache.config.Configuration.NodeLockingScheme#OPTIMISTIC} @author Manik Surtani (manik AT jboss DOT org) @author Steve Woodcock (stevew@jofti.com) @since 1.3.0 @deprecated will be removed along with optimistic and pessimistic locking.
