Deprecated.

will be removed along with optimistic and pessimistic locking.

@Deprecated
public class VersionedNode<K,V>
extends PessimisticUnversionedNode<K,V>

VersionedNode extends the UnversionedNode by adding a DataVersion property.

Unlike UnversionedNode, this node supports getVersion() and setVersion(org.jboss.cache.optimistic.DataVersion) defined in NodeSPI

Typically used when the cache mode configured is Configuration.NodeLockingScheme.OPTIMISTIC

Since:

2.0.0

Description copied from interface: InternalNode

Creates a new instance of the same type and copies internal state. Note that a shallow copy is made for all fields except the data map, where a new map is created.

Specified by:

copy in interface InternalNode<K,V>

Overrides:

copy in class PessimisticUnversionedNode<K,V>

Returns:

a copy.
