MooseX::Storage::Format::JSON - A JSON serialization role
=head1 SYNOPSIS
package Point;
use Moose;
use MooseX::Storage;
with Storage('format' => 'JSON');
has 'x' => (is => 'rw', isa => 'Int');
has 'y' => (is => 'rw', isa => 'Int');
1;
my $p = Point->new(x => 10, y => 10);
## methods to freeze/thaw into
## a specified serialization format
## (in this case JSON)
# pack the class into a JSON string
$p->freeze(); # { "__CLASS__" : "Point", "x" : 10, "y" : 10 }
# unpack the JSON string into a class
my $p2 = Point->thaw('{ "__CLASS__" : "Point", "x" : 10, "y" : 10 }');
