Moose::Meta::Role::Attribute

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

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 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.
