Examples of org.dbwiki.data.time.Version

org.dbwiki.data.time.Version
Interface to Version information. A Version is a struct containing a name, number, TimestampPrinter, Provenance, and time The name is basically a date-time string stored in the database. FIXME #time: Eliminate version names, recalculate from _time instead @author jcheney

        nid = new NodeIdentifier(nodeId);
      Provenance provenance =
        ProvenanceFactory.getProvenance((byte)rs.getInt(RelVersionColProvenance),

      this.add(new Version(versionNumber, versionName, createTime, provenance, this));
