Interface DataVersion

All Superinterfaces:
java.io.Serializable
All Known Implementing Classes:
DefaultDataVersion

public interface DataVersion
extends java.io.Serializable

When versioning data nodes in optimistic locking, a DataVersion is assigned to each node. Versions need to implement the newerThan(org.jboss.cache.optimistic.DataVersion) method so they can be compared during the validation phase upon commit.
