MooseX::Clone::Meta::Attribute::Trait::StorableClone(3) User Contributed Perl Documentation MooseX::Clone::Meta::Attribute::Trait::StorableClone(3)
 

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

version 0.06

    # see MooseX::Clone
    has foo => (
        traits => [qw(StorableClone)],
        isa => "Something",
    );
    my $clone = $object->clone; # $clone->foo will equal Storable::dclone($object->foo)

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.

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.

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.

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.
