65 MooseX::Storage::Basic - The simplest level of serialization
75 has 'x' => (is => 'rw', isa => 'Int');
76 has 'y' => (is => 'rw', isa => 'Int');
80 my $p = Point->new(x => 10, y => 10);
82 ## methods to pack/unpack an
83 ## object in perl data structures
85 # pack the class into a hash
86 $p->pack(); # { __CLASS__ => 'Point-0.01', x => 10, y => 10 }
88 # unpack the hash into a class
89 my $p2 = Point->unpack({ __CLASS__ => 'Point-0.01', x => 10, y => 10 });
91 # unpack the hash, with insertion of paramaters
92 my $p3 = Point->unpack( $p->pack, inject => { x => 11 } );
96 This is the most basic form of serialization. This is used by default
97 but the exported C<Storage> function.
103 =item B<pack ([ disable_cycle_check => 1])>
105 Providing the C<disable_cycle_check> argument disables checks for any cyclical
106 references. The current implementation for this check is rather naive, so if
107 you know what you are doing, you can bypass this check.
109 This trait is applied on a perl-case basis. To set this flag for all objects
110 that inherit from this role, see L<MooseX::Storage::Traits::DisableCycleDetection>.
112 =item B<unpack ($data [, insert => { key => val, ... } ] )>
114 Providing the C<insert> argument let's you supply additional arguments to
115 the class' C<new> function, or override ones from the serialized data.
129 All complex software has bugs lurking in it, and this module is no
