NAME
    TableData::Object - Manipulate table data

VERSION
    This document describes version 0.01 of TableData::Object (from Perl
    distribution TableData-Object), released on 2014-08-16.

SYNOPSIS
     use TableData::Object qw(table);

     $td = TableData::Object->new([1, 2, 3, 4]);  # from array of scalars
     $td = TableData::Object->new([[1,2],[2,3]]); # from array of arrays of scalars
     $td = TableData::Object->new([{name=>"Andi"}, {name=>"Budi", gender=>"m"}]);
                                                  # from array of hashes of scalars
     $td = TableData::Object->new(4); # die, can only accept in the above form

     # shortcut to construct object
     $td = table(...);

     # for the examples below, this object is assumed
     $td = TableData::Object->new([["Andi",3000], ["Budi",4000], ["Cinta",2500]]);

     # retrieve names of columns
     $cols = $td->columns; # -> ["column0", "column1"]

     # set names of columns
     $td->columns(["name", "salary"]);

     # retrieve a single column
     $col = $td->column("salary"); # -> [3000,4000,2500]
     $col = $td->column("foo");    # dies, unknown column

     # retrieve rows data, each row as arrays
     $rows = $td->rows_as_array; # -> (["Andi",3000], ["Budi",4000], ["Cinta",2500])

     # retrieve rows data, each row as hash
     $rows = $td->rows_as_hash; # -> ({name=>"Andi",salary=>3000}, {name=>"Budi",salary=>4000}, {name=>"Cinta",salary=>2500})

     # retrieve a specific row
     $row = $td->row_as_array(2); # -> ["Cinta",2500]
     $row = $td->row_as_hash(1); # -> [{name=>"Budi",salary=>4000}]

     # convert to specific forms
     $data = $td->as_aoaos;
     $data = $td->as_aohos;

     # XXX add row

     # XXX add column

     # XXX delete row(s)

     # XXX delete column(s)

     # XXX rename column

     # XXX reorder column

DESCRIPTION
    This module provides a class to manipulate table data. Table data can be
    in the form of array of scalars (aos), array of arrays of scalars
    (aoaos), or array of hashes of scalars (aohos). There are methods to
    get/set the columns/rows, convert to the other forms, etc.

    Aos data is assumed to be a single-column table with column named "data"
    (but this can be renamed). Aoaos data is assumed to have columns named
    "column0", "column1", and so on (but this can be changed). Aohos data is
    assumed to have columns according to the hash keys (sorted
    alphabetically) and column names cannot be changed.

FUNCTIONS
  table($data[, $spec]) => obj
    Exportable. Shortcut for constructor.

METHODS
  new($data[, $spec]) => obj
    Constructor.

    $spec is optional and should be table specification hash according
    TableDef.

  columns([ $cols ]) => array
    Get or set columns.

  column_data($name) => array
    Get a single column data.

  rows_as_array => array of array of scalar
  rows_as_hash => array of hash of scalar
  row_as_array($index) => array of scalar
  row_as_hash($index) => hash of scalar
  as_aoaos() => array of array of scalar
  as_aohos() => array of hash of scalar
