Tie::DataDumper - Stores your object when untied via DataDumper
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; }
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($variable)->save but the whole idea is not to forget to save it.
tied($variable)->save
This module uses DataDumper as its backend so it can store and retrieve anything that DataDumper can.
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.
