MooseX::Clone::Meta::Attribute::Trait::StorableClone - The attribute trait for deeply cloning attributes using Storable
# 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
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 Right™ way.
If true then non object values will be copied over in shallow cloning semantics (shared reference).
Defaults to false (all reference will be cloned).
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.
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.
Clones the value the attribute encapsulates from
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.
This is the actual workhorse of
clone_visitor to clone all non object values.
clone_value_data if the value is not an object and
clone_only_objects is false.
