NAME

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

VERSION

       version 0.06

SYNOPSIS

           # see MooseX::Clone

           has foo => (
               traits => [qw(Clone)],
               isa => "Something",
           );

           $object->clone; # will recursively call $object->foo->clone and set the value properly

DESCRIPTION

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

DERIVATION

       Deriving this role for your own cloning purposes is encouraged.

       This will allow your fine grained cloning semantics to interact with MooseX::Clone in the
       RightX way.

ATTRIBUTES

       clone_only_objects
           Whether or not Data::Visitor should be used to clone arbitrary structures.  Objects
           found in these structures will be cloned using clone_object_value.

           If true then non object values will be copied over in shallow cloning semantics
           (shared reference).

           Defaults to false (all reference will be cloned).

       clone_visitor_config
           A hash ref used to construct "clone_visitor". Defaults to the empty ref.

           This can be used to alter the cloning behavior for non object values.

       clone_visitor
           The Data::Visitor::Callback object that will be used to clone.

           It has an "object" handler that delegates to "clone_object_value" and sets
           "tied_as_objects" to true in order to deeply clone tied structures while retaining
           magic.

           Only used if "clone_only_objects" is false and the value of the attribute is not an
           object.

METHODS

       clone_value $target, $proto, %args
           Clones the value the attribute encapsulates from $proto into $target.

       clone_value_data $value, %args
           Does the actual cloning of the value data by delegating to a "clone" method on the
           object if any.

           If the object does not support a "clone" method an error is thrown.

           If the value is not an object then it will not be cloned.

           In the future support for deep cloning of simple refs will be added too.

       clone_object_value $object, %args
           This is the actual workhorse of "clone_value_data".

       clone_any_value $value, %args
           Uses "clone_visitor" to clone all non object values.

           Called from "clone_value_data" if the value is not an object and "clone_only_objects"
           is false.
