MooseX::Traits::Pluggable - trait loading and resolution for Moose
See MooseX::Traits for usage information.
Use new_with_traits to construct an object with a list of traits and apply_traits to apply traits to an instance.
new_with_traits
apply_traits
Adds support for class precedence search for traits and some extra attributes, described below.
If the value of "_trait_namespace" in MooseX::Traits starts with a + the namespace will be considered relative to the class_precedence_list (ie. @ISA) of the original class.
+
class_precedence_list
@ISA
Example:
package Class1 use Moose; package Class1::Trait::Foo; use Moose::Role; has 'bar' => ( is => 'ro', isa => 'Str', required => 1, ); package Class2; use parent 'Class1'; with 'MooseX::Traits'; has '+_trait_namespace' => (default => '+Trait'); has '+_traits_behave_like_roles' => (default => 1); package Class2::Trait::Bar; use Moose::Role; has 'baz' => ( is => 'ro', isa => 'Str', required => 1, ); package main; my $instance = Class2->new_with_traits( traits => ['Foo', 'Bar'], bar => 'baz', baz => 'quux', ); $instance->does('Class1::Trait::Foo'); # true $instance->does('Class2::Trait::Bar'); # true
You can search multiple namespaces for traits, for example:
has '+_trait_namespace' => ( default => sub { [qw/+Trait +Role ExtraNS::Trait/] } );
Will search in the class_precedence_list for ::Trait::TheTrait and ::Role::TheTrait and then for ExtraNS::Trait::TheTrait.
::Trait::TheTrait
::Role::TheTrait
ExtraNS::Trait::TheTrait
By default, a method from a role will override a class method, this however is not the behavior one expects when applying a Moose role using the normal methods.
If you want the behavior to be consistent with Moose roles, then use this configuration attribute in your class:
has '+_traits_behave_like_roles' => (default => 1);
This may or may not become the default in the future, for now you have to ask for it for backward compatibility reasons.
When traits are applied to your class or instance, you get an anonymous class back whose name will be not the same as your original class. So ref $self will not be Class, but $self->_original_class_name will be.
ref $self
Class
$self->_original_class_name
List of the (unresolved) traits applied to the instance.
List of traits applied to the instance resolved to full package names.
