nexj.core.meta.integration.format.fixed.FixedMessagePartMapping
Represents a mapping between a MessagePart and a field or a record (a set of fields) or the file (the entire set of records) in a Fixed Length Field file ("flat file database").

      m_writer = out.getWriter();


      FixedMessagePartMapping rootMapping = (FixedMessagePartMapping)rootPart.getMapping();

      {
         m_writer.write(rootMapping.getPrefix());


         Object toFormat = tobj.findValue(recordPart.getName());
