Examples of ORecordVersion

com.orientechnologies.orient.core.version.ORecordVersion
Abstraction for record version. In non distributed environment it is just a number represented by {@link OSimpleVersion}. In distributed environment records can be processed concurrently, so simple number is not enough, as we need some additional information to prevent generation of two different versions of document with the same version number. This interface provide an ability to create extended versions. @author Artem Orobets @see OSimpleVersion @see ODistributedVersion
