NAME

PDL::IO::Storable - helper functions to make PDL usable with Storable


SYNOPSIS

  use Storable;
  use PDL::IO::Storable;
  $hash = {
            'foo' => 42,
            'bar' => zeroes(23,45),
          };
  store $hash, 'perlhash.dat';


DESCRIPTION

Storable implements object persistence for Perl data structures that can (in principle) contain arbitrary Perl objects. Complicated objects must supply their own methods to be serialized and thawed. This module implements the relevant methods to be able to store and retrieve piddles via Storable.


FUNCTIONS

store

store a piddle using Storable

  $a = random 12,10;
  $a->store('myfile');

freeze

freeze a piddle using Storable

  $a = random 12,10;
  $frozen = $a->freeze;


BUGS

The packed piddles are not stored in a network transparent way. As a result expect problems when moving Storable data containing piddles across computers.

This could be fixed by amending the methods pdlpack and pdlunpack appropriately. If you want this functionality feel free to submit patches.

If you want to move piddle data across platforms I recommend PDL::NetCDF as an excellent (and IMHO superior) workaround.
