Moose::Meta::Role::Attribute.3pm

NAME

Moose::Meta::Role::Attribute - A Moose Attribute metaclass for Roles

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

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_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).

BUGS

See ``BUGS'' in Moose for details on reporting bugs.
