NAME ^

Tie::DataDumper - Stores your object when untied via DataDumper

SYNOPSIS ^

  use Tie::DataDumper;
  {
      tie my $scalar => 'Tie::DataDumper', 'scalar.pl';
      $scalar = 42;
  } # scalar is automatically saved as 'scalar.pl'.
  {
      tie my @array => 'Tie::DataDumper', 'array.pl';
      @array = qw(Sun Mon Tue Wed Fri Sat);
  } # array is automatically saved as 'array.pl'.
  {
      tie my %hash => 'Tie::DataDumper', 'hash.pl';
      %hash = (Sun=>0, Mon=>1, Tue=>2, Wed=>3, Thu=>4, Fri=>5, Sat=>6);
  } # hash is automatically saved as 'hash.pl'.
  {
      tie my $object => 'Tie::DataDumper', 'object.pl';
      $object = bless { First => 'Dan', Last => 'Kogai' }, 'DANKOGAI';
  } # You can save an object; just pass a scalar
  {
      tie my $object => 'Tie::DataDumper', 'object.pl';
      $object->{WIFE} =  { First => 'Naomi', Last => 'Kogai' };
      # you can save before you untie like this
      tied($object)->save;
  }

DESCRIPTION ^

Tie::DataDumper stores tied variables when untied. Usually that happens when you variable is out of scope. You can of course explicitly untie the variable or tied($variable)->save but the whole idea is not to forget to save it.

This module uses DataDumper as its backend so it can store and retrieve anything that DataDumper can.

SECURITY ^

This module uses eval() on loading saved files. That means there is a security risk of executing malicious codes. DO NOT USE THIS MODULE FOR ANYTHING SERIOUS. This module is just a proof-of-concept, example module to show how to make use of Tie::SaveLater.
