NAME

       MooseX::Clone - Fine-grained cloning support for Moose objects.

VERSION

       version 0.06

SYNOPSIS

           package Bar;
           use Moose;

           with qw(MooseX::Clone);

           has foo => (
               isa => "Foo",
               traits => [qw(Clone)], # this attribute will be recursively cloned
           );

           package Foo;
           use Moose;

           # this API is used/provided by MooseX::Clone
           sub clone {
               my ( $self, %params ) = @_;

               # ...
           }

           # used like this:

           my $bar = Bar->new( foo => Foo->new );

           my $copy = $bar->clone( foo => [ qw(Args for Foo::clone) ] );

DESCRIPTION

       Out of the box Moose only provides very barebones cloning support in order to maximize
       flexibility.

       This role provides a "clone" method that makes use of the low level cloning support
       already in Moose and adds selective deep cloning based on introspection on top of that.
       Attributes with the "Clone" trait will handle cloning of data within the object, typically
       delegating to the attribute value's own "clone" method.

TRAITS

       Clone
           By default Moose objects are cloned like this:

               bless { %$old }, ref $old;

           By specifying the Clone trait for certain attributes custom behavior the value's own
           "clone" method will be invoked.

           By extending this trait you can create custom cloning for certain attributes.

           By creating "clone" methods for your objects (e.g. by composing MooseX::Compile) you
           can make them interact with this trait.

       NoClone
           Specifies attributes that should be skipped entirely while cloning.

METHODS

       clone %params
           Returns a clone of the object.

           All attributes which do the MooseX::Clone::Meta::Attribute::Trait::Clone role will
           handle cloning of that attribute. All other fields are plainly copied over, just like
           in "clone_object" in Class::MOP::Class.

           Attributes whose "init_arg" is in %params and who do the "Clone" trait will get that
           argument passed to the "clone" method (dereferenced). If the attribute does not self-
           clone then the param is used normally by "clone_object" in Class::MOP::Class, that is
           it will simply shadow the previous value, and does not have to be an array or hash
           reference.

TODO

       Refactor to work in term of a metaclass trait so that "meta->clone_object" will still do
       the right thing.
