NAME

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

VERSION

10       version 0.06
11

SYNOPSIS

13           # see MooseX::Clone
14
15           has foo => (
16               traits => [qw(Clone)],
17               isa => "Something",
18           );
19
20           $object->clone; # will recursively call $object->foo->clone and set the value properly
21

DESCRIPTION

23       This meta attribute trait provides a "clone_value" method, in the
24       spirit of "get_value" and "set_value". This allows clone methods such
25       as the one in MooseX::Clone to make use of this per-attribute cloning
26       behavior.
27

DERIVATION

29       Deriving this role for your own cloning purposes is encouraged.
30
31       This will allow your fine grained cloning semantics to interact with
32       MooseX::Clone in the RightX way.
33

ATTRIBUTES

35       clone_only_objects
36           Whether or not Data::Visitor should be used to clone arbitrary
37           structures.  Objects found in these structures will be cloned using
38           clone_object_value.
39
40           If true then non object values will be copied over in shallow
41           cloning semantics (shared reference).
42
43           Defaults to false (all reference will be cloned).
44
45       clone_visitor_config
46           A hash ref used to construct "clone_visitor". Defaults to the empty
47           ref.
48
49           This can be used to alter the cloning behavior for non object
50           values.
51
52       clone_visitor
53           The Data::Visitor::Callback object that will be used to clone.
54
55           It has an "object" handler that delegates to "clone_object_value"
56           and sets "tied_as_objects" to true in order to deeply clone tied
57           structures while retaining magic.
58
59           Only used if "clone_only_objects" is false and the value of the
60           attribute is not an object.
61

METHODS

63       clone_value $target, $proto, %args
64           Clones the value the attribute encapsulates from $proto into
65           $target.
66
67       clone_value_data $value, %args
68           Does the actual cloning of the value data by delegating to a
69           "clone" method on the object if any.
70
71           If the object does not support a "clone" method an error is thrown.
72
73           If the value is not an object then it will not be cloned.
74
75           In the future support for deep cloning of simple refs will be added
76           too.
77
78       clone_object_value $object, %args
79           This is the actual workhorse of "clone_value_data".
80
81       clone_any_value $value, %args
82           Uses "clone_visitor" to clone all non object values.
83
84           Called from "clone_value_data" if the value is not an object and
85           "clone_only_objects" is false.
