62 MooseX::Storage::Basic - The simplest level of serialization
70 our $VERSION = '0.01';
74 has 'x' => (is => 'rw', isa => 'Int');
75 has 'y' => (is => 'rw', isa => 'Int');
79 my $p = Point->new(x => 10, y => 10);
81 ## methods to pack/unpack an
82 ## object in perl data structures
84 # pack the class into a hash
85 $p->pack(); # { __CLASS__ => 'Point-0.01', x => 10, y => 10 }
87 # unpack the hash into a class
88 my $p2 = Point->unpack({ __CLASS__ => 'Point-0.01', x => 10, y => 10 });
90 # unpack the hash, with insertion of paramaters
91 my $p3 = Point->unpack( $p->pack, inject => { x => 11 } );
95 This is the most basic form of serialization. This is used by default
96 but the exported C<Storage> function.
102 =item B<pack ([ disable_cycle_check => 1])>
104 Providing the C<disable_cycle_check> argument disables checks for any cyclical
105 references. The current implementation for this check is rather naive, so if
106 you know what you are doing, you can bypass this check.
108 This trait is applied on a perl-case basis. To set this flag for all objects
109 that inherit from this role, see L<MooseX::Storage::Traits::DisableCycleDetection>.
111 =item B<unpack ($data [, insert => { key => val, ... } ] )>
113 Providing the C<insert> argument let's you supply additional arguments to
114 the class' C<new> function, or override ones from the serialized data.
128 All complex software has bugs lurking in it, and this module is no
