MooseX::Storage::Basic - The simplest level of serialization
VERSION
version 0.45
SYNOPSIS
package Point;
use Moose;
use MooseX::Storage;
with Storage;
has 'x' => (is => 'rw', isa => 'Int');
has 'y' => (is => 'rw', isa => 'Int');
1;
my $p = Point->new(x => 10, y => 10);
## methods to pack/unpack an
## object in perl data structures
# pack the class into a hash
$p->pack(); # { __CLASS__ => 'Point-0.01', x => 10, y => 10 }
# unpack the hash into a class
my $p2 = Point->unpack({ __CLASS__ => 'Point-0.01', x => 10, y => 10 });
# unpack the hash, with insertion of paramaters
my $p3 = Point->unpack( $p->pack, inject => { x => 11 } );
DESCRIPTION
This is the most basic form of serialization. This is used by default but the exported "Storage" function.
METHODS
pack ([ disable_cycle_check = 1])>
Providing the "disable_cycle_check" argument disables checks for any cyclical references. The current implementation for this check is
rather naive, so if you know what you are doing, you can bypass this check.
This trait is applied on a perl-case basis. To set this flag for all objects that inherit from this role, see
MooseX::Storage::Traits::DisableCycleDetection.
unpack ($data [, insert = { key => val, ... } ] )>
Providing the "insert" argument let's you supply additional arguments to the class' "new" function, or override ones from the
serialized data.
