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

VERSION
    version 2.2200

DESCRIPTION
    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.

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 of "associated_role()" for attributes in a composite role, or when 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).
