💖 MooseX::Clone::Meta::Attribute::Trait::StorableClone 💖

okay so bestie, welcome to the User Contributed Perl Documentation section, and this little icon is MooseX::Clone::Meta::Attribute::Trait::StorableClone. long name? yes. worth it? also yes. it's the attribute trait that deep-clones your attributes using Storable, and honestly it's giving main character energy for like six lines of code. 🎀

---

✨ VERSION ✨

version 0.06 — vintage but iconic, no cap. 🦋

---

🌸 SYNOPSIS 🌸

# see MooseX::Clone

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

my $clone = $object->clone; # $clone->foo will equal Storable::dclone($object->foo)

so you slap the trait on, and boom 💅 the clone comes out deep-copied, $clone->foo equals Storable::dclone($object->foo).

---

🦋 DESCRIPTION 🦋

This meta attribute trait hands you a clone_value method, and it lives in the same friend group as get_value and set_value. which means clone methods — like the one over in MooseX::Clone — can use this per-attribute cloning behavior. it's giving pluggable cloning, fr fr. ✨

---

💅 DERIVATION 💅

Deriving this role for your own cloning purposes is encouraged. periodt. 🫶

This will let your fine grained cloning semantics interact with MooseX::Clone in the RightX way. iykyk. 😌

---

👑 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). 😭 yes, shared. be normal about it.

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. 🧚 magic retained, as a treat.

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. 💀 so like, don't.

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. (future plans, not current facts, bestie — manifesting ✨)

• clone_object_value $object, %args — This is the actual workhorse of clone_value_data. 🐎 the one doing all the heavy lifting while everyone else takes credit.
• 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.
