## org.jboss.cache.optimistic
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.
