Class VersionedNode<K,V>

java.lang.Object
  org.jboss.cache.AbstractNode<K,V>
      org.jboss.cache.UnversionedNode<K,V>
          org.jboss.cache.VersionedNode<K,V>

All Implemented Interfaces:

Node<K,V>, NodeSPI<K,V>

public class VersionedNode<K,V>
extends UnversionedNode<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
