NAME

6       MooseX::Clone::Meta::Attribute::Trait::Clone - The
7       Moose::Meta::Attribute trait for deeply cloning attributes.
8

SYNOPSIS

10           # see MooseX::Clone
11
12           has foo => (
13               traits => [qw(Clone)],
14               isa => "Something",
15           );
16
17           $object->clone; # will recursively call $object->foo->clone and set the value properly
18

DESCRIPTION

20       This meta attribute trait provides a "clone_value" method, in the
21       spirit of "get_value" and "set_value". This allows clone methods such
22       as the one in MooseX::Clone to make use of this per-attribute cloning
23       behavior.
24

DERIVATION

26       Deriving this role for your own cloning purposes is encouraged.
27
28       This will allow your fine grained cloning semantics to interact with
29       MooseX::Clone in the RightX way.

ATTRIBUTES

32       clone_only_objects
33           Whether or not Data::Visitor should be used to clone arbitrary
34           structures.  Objects found in these structures will be cloned using
35           clone_object_value.
36
37           If true then non object values will be copied over in shallow
38           cloning semantics (shared reference).
39
40           Defaults to false (all reference will be cloned).
41
42       clone_visitor_config
43           A hash ref used to construct "clone_visitor". Defaults to the empty
44           ref.
45
46           This can be used to alter the cloning behavior for non object
47           values.
48
49       clone_visitor
50           The Data::Visitor::Callback object that will be used to clone.
51
52           It has an "object" handler that delegates to "clone_object_value"
53           and sets "tied_as_objects" to true in order to deeply clone tied
54           structures while retaining magic.
55
56           Only used if "clone_only_objects" is false and the value of the
57           attribute is not an object.
58

METHODS

60       clone_value $target, $proto, %args
61           Clones the value the attribute encapsulates from $proto into
62           $target.
63
64       clone_value_data $value, %args
65           Does the actual cloning of the value data by delegating to a
66           "clone" method on the object if any.
67
68           If the object does not support a "clone" method an error is thrown.
69
70           If the value is not an object then it will not be cloned.
71
72           In the future support for deep cloning of simple refs will be added
73           too.
74
75       clone_object_value $object, %args
76           This is the actual workhorse of "clone_value_data".
77
78       clone_any_value $value, %args
79           Uses "clone_visitor" to clone all non object values.
80
81           Called from "clone_value_data" if the value is not an object and
82           "clone_only_objects" is false.
