NAME
       Geo::TigerLine::Record::Parser - Parsing superclass for TIGER/Line records.

SYNOPSIS
         package Geo::TigerLine::Record::23;
         use base qw(Geo::TigerLine::Record::Parser);

         @records = __PACKAGE__->parse_file($fh);
         __PACKAGE__->parse_file($fh, \&callback);

         $record = __PACKAGE__->parse($row);

DESCRIPTION
       Parses raw TIGER/Line data into Geo::TigerLine::Record objects.  This is intended to be
       used as a superclass of Geo::TigerLine::Record objects and not used directly.

       You shouldn't be here.

   Methods
       parse_file
               @records = __PACKAGE__->parse_file($fh);
               __PACKAGE__->parse_file($fh, \&callback);

           Parses a given filehandle as a TIGER/Line data file.  The data definition is taken
           from __PACKAGE__->Pack_Tmpl, __PACKAGE__->Dict and __PACKAGE__->Fields.  Returns an
           array of objects of type __PACKAGE__.

           &callback will be called for each record and given a record object and its position in
           the file (ie. 1 for the first, 2 for the second, etc...).  A sample callback...

               sub callback {
                   my($record, $pos) = @_;

                   printf "Record #$pos is %s\n", $record->tlid;
               }

           If a &callback is given, a list of records will NOT be returned.  It is assumed you'll
           be taking care of arrangements to store the records in your callback and @records can
           eat up huge amounds of memory for a typical TIGER/Line data file.

       parse
               $record = __PACKAGE__->parse($line);

           Parses a single record of TIGER/Line data.
