NAME ^

Geo::TigerLine::Record::T - TIGER/Line 2003 TIGER Zero-Cell ID

SYNOPSIS ^

  use Geo::TigerLine::Record::T;

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

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

  $record->rt();
  $record->version();
  $record->file();
  $record->tzid();
  $record->source();
  $record->ftrp();

DESCRIPTION ^

This is a class representing record type T of the TIGER/Line 2003 census geographic database. Each object is one record. It also contains methods to parse TIGER/Line record type T 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 sophisticated (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 validation.

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

Record Type.

Expects alphanumeric data of no more than 1 characters. $data cannot 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);

File Code.

Expects numeric data of no more than 5 characters. $data cannot be blank and should be left justified.

tzid
    $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 be blank and should be right justified.

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

TIGER Zero-Cell Source Code (not filled).

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

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

FTRP ID (AAAAA.O.XXXXXXXXX) (Authority-P-ID) FGDC Transportation ID Standard (not filled).

Expects alphanumeric data of no more than 17 characters. $data can be blank and should be left justified.

Data dictionary

This is the original TIGER/Line 2003 data dictionary from which this class was generated.
