Moose::Meta::Role::Attribute - The Moose attribute metaclass for Roles

version 2.0010

This class implements the API for attributes in roles. Attributes in roles are more like attribute prototypes than full blown attributes. While they are introspectable, they have very little behavior.

This class provides the following methods:

Moose::Meta::Role::Attribute->new(...)

This method accepts all the options that would be passed to the constructor for Moose::Meta::Attribute.

$attr->metaclass

$attr->is

Returns the option as passed to the constructor.

$attr->associated_role

Returns the Moose::Meta::Role to which this attribute belongs, if any.

$attr->original_role

Returns the Moose::Meta::Role in which this attribute was first defined. This may not be the same as the value associated_role() in the case of composite role, or the case where one role consumes other roles.

$attr->original_options

Returns a hash reference of options passed to the constructor. This is used when creating a Moose::Meta::Attribute object from this object.

$attr->attach_to_role($role)

Attaches the attribute to the given Moose::Meta::Role.

$attr->attribute_for_class($metaclass)

Given an attribute metaclass name, this method calls $metaclass->interpolate_class_and_new to construct an attribute object which can be added to a Moose::Meta::Class.

$attr->clone

Creates a new object identical to the object on which the method is called.

$attr->is_same_as($other_attr)

Compares two role attributes and returns true if they are identical.

In addition, this class implements all informational predicates implements by Moose::Meta::Attribute (and Class::MOP::Attribute).
