NAME MooseX::Storage::MaybeDeferred - A role for the less indecisive programmers VERSION 0.0.4 SYNOPSIS package Point; use Moose; use MooseX::Storage; with MooseX::Storage::MaybeDeferred => { default_format => 'JSON', default_io => 'File', }; has 'x' => (is => 'rw', isa => 'Int'); has 'y' => (is => 'rw', isa => 'Int'); 1; my $p = Point->new(); $p->freeze(); # or $p->freeze({format => 'Storable'}); ... $p->store($filename); $p->store($filename, {format => 'Storable', io => 'AtomicFile'}); ... my $another_point; $another_point = Point->load($filename); # or $another_point = Point->load($filename, {format => 'JSON', io => 'File'}); DESCRIPTION With the module MooseX::Storage you are hard coding the definition of the "format" and maybe "io" layer in the classes you want to serialize. Whenever the methods "freeze" or "store" are called, it is not possible to to change their behaviour. You always get what you have declared. If you need to serialize into different formats you can use MooseX::Storage::Deferred. Now, whenever you call "freeze" or "store" you must provide parameters which define the format and the io layer. This module should give you the benefits of both worlds. You need to provide the "default_format" and "default_io" layers in the definitions of the classes which you want to serialize. So classes that used to use MooseX::Storage should still behave as before. But if you need to serialize into a different format you have the flexibility of MooseX::Storage::Deferred. Now you can provide the "format" and "io" setting at runtime. SEE ALSO MooseX::Storage MooseX::Storage::Deferred ACKNOWLEDGEMENTS Thanks www.netdescribe.com.
