Examples of VersionedValue

org.apache.cassandra.gms.VersionedValue
This abstraction represents the state associated with a particular node which an application wants to make available to the rest of the nodes in the cluster. Whenever a piece of state needs to be disseminated to the rest of cluster wrap the state in an instance of ApplicationState and add it to the Gossiper. e.g. if we want to disseminate load information for node A do the following: ApplicationState loadState = new ApplicationState(); Gossiper.instance.addApplicationState("LOAD STATE", loadState);
org.infinispan.client.hotrod.VersionedValue
Besides the key and value, also contains an version. To be used in versioned operations, e.g. {@link org.infinispan.client.hotrod.RemoteCache#removeWithVersion(Object,long)}. @author Mircea.Markus@jboss.com
