code: public void write(RowOutputInterface out) {
  
          out.writeSize(storageSize);
          out.writeData(rowData, tTable.colTypes);
          out.writeEnd();
  
          hasDataChanged = false;
      }
docs: Writes the data to disk. Unlike CachedRow, hasChanged is never set
  to true when changes are made to the Nodes. (Nodes are in-memory).
  The only time this is used is when a new Row is added to the Caches.
