NAME
       Geo::TigerLine::Record::U - TIGER/Line 2003 TIGER/Line ID Over-
       pass/Underpass Identification

SYNOPSIS
         use Geo::TigerLine::Record::U;

         @records = Geo::TigerLine::Record::U->parse_file($fh);
         @records = Geo::TigerLine::Record::U->parse_file($fh, \&callback);

         $record = Geo::TigerLine::Record::U->new(\%fields);

         $record->rt();
         $record->version();
         $record->file();
         $record->tzid();
         $record->rtsq();
         $record->tlidov1();
         $record->tlidov2();
         $record->tlidun1();
         $record->tlidun2();
         $record->frlong();
         $record->frlat();

DESCRIPTION
       This is a class representing record type U of the TIGER/Line 2003 cen-
       sus geographic database.  Each object is one record.  It also contains
       methods to parse TIGER/Line record type U files and turn them into
       objects.

       This is intended as an intermediate format between pulling the raw data
       out of the simplistic TIGER/Line data files into something more sophis-
       ticated (a process you should only have to do once).  As such, it's not
       very fast, but its careful, easy to use and performs some verifications
       on the data being read.

       As this class is autogenerated by mk_parsers, think before you modify
       this file.  It's OO, so consider sub-classing instead.

       Accessors

       These are simple get/set accessors for each field of a record generated
       from the TIGER/Line 2003 data dictionary.  They perform some data vali-
       dation.

       rt
               $data = $record->rt();
               $record->rt($data);

           Record Type.

           Expects alphanumeric data of no more than 1 characters.  $data can-
           not be blank and should be left justified.

       version
               $data = $record->version();
               $record->version($data);

           Version Number.

           Expects numeric data of no more than 4 characters.  $data cannot be
           blank and should be left justified.

       file
               $data = $record->file();
               $record->file($data);

               $data = $record->tzid();
               $record->tzid($data);

           TIGER Zero-Cell ID, Permanent Zero-Cell Number.

           Expects numeric data of no more than 10 characters.  $data cannot

       rtsq
               $data = $record->rtsq();
               $record->rtsq($data);

           Expects numeric data of no more than 1 characters.  $data cannot be
           blank and should be right justified.

           TIGER/Line ID, First Overpass 1-Cell Number.

           Expects numeric data of no more than 10 characters.  $data can be
           blank and should be right justified.

       tlidov2
               $data = $record->tlidov2();
               $record->tlidov2($data);

           TIGER/Line ID, Second Overpass 1-Cell Number.

           Expects numeric data of no more than 10 characters.  $data can be
           blank and should be right justified.

       tlidun1
               $data = $record->tlidun1();
               $record->tlidun1($data);

           TIGER/Line ID, First Underpass 1-Cell Number.

           Expects numeric data of no more than 10 characters.  $data can be
           blank and should be right justified.
