58 has 'y' => (is => 'rw', isa => 'Int');
62 my $p = Point->new(x => 10, y => 10);
64 ## methods to pack/unpack an
65 ## object in perl data structures
67 # pack the class into a hash
68 $p->pack(); # { __CLASS__ => 'Point-0.01', x => 10, y => 10 }
70 # unpack the hash into a class
71 my $p2 = Point->unpack({ __CLASS__ => 'Point-0.01', x => 10, y => 10 });
73 # unpack the hash, with insertion of paramaters
74 my $p3 = Point->unpack( $p->pack, inject => { x => 11 } );
78 This is the most basic form of serialization. This is used by default
79 but the exported C<Storage> function.
85 =item B<pack ([ disable_cycle_check => 1])>
87 Providing the C<disable_cycle_check> argument disables checks for any cyclical
88 references. The current implementation for this check is rather naive, so if
89 you know what you are doing, you can bypass this check.
91 This trait is applied on a perl-case basis. To set this flag for all objects
92 that inherit from this role, see L<MooseX::Storage::Traits::DisableCycleDetection>.
94 =item B<unpack ($data [, insert => { key => val, ... } ] )>
96 Providing the C<insert> argument let's you supply additional arguments to
97 the class' C<new> function, or override ones from the serialized data.
