136 |  |  |  |  | =head1 NAME
137 |  |  |  |  |
138 |  |  |  |  | Moose::Meta::Role::Attribute - The Moose attribute metaclass for Roles
139 |  |  |  |  |
140 |  |  |  |  | =head1 VERSION
141 |  |  |  |  |
142 |  |  |  |  | version 2.0602
143 |  |  |  |  |
144 |  |  |  |  | =head1 DESCRIPTION
145 |  |  |  |  |
146 |  |  |  |  | This class implements the API for attributes in roles. Attributes in roles are
147 |  |  |  |  | more like attribute prototypes than full blown attributes. While they are
148 |  |  |  |  | introspectable, they have very little behavior.
149 |  |  |  |  |
150 |  |  |  |  | =head1 METHODS
151 |  |  |  |  |
152 |  |  |  |  | This class provides the following methods:
153 |  |  |  |  |
154 |  |  |  |  | =over 4
155 |  |  |  |  |
156 |  |  |  |  | =item B<< Moose::Meta::Role::Attribute->new(...) >>
157 |  |  |  |  |
158 |  |  |  |  | This method accepts all the options that would be passed to the constructor
159 |  |  |  |  | for L<Moose::Meta::Attribute>.
160 |  |  |  |  |
161 |  |  |  |  | =item B<< $attr->metaclass >>
162 |  |  |  |  |
163 |  |  |  |  | =item B<< $attr->is >>
164 |  |  |  |  |
165 |  |  |  |  | Returns the option as passed to the constructor.
166 |  |  |  |  |
167 |  |  |  |  | =item B<< $attr->associated_role >>
168 |  |  |  |  |
169 |  |  |  |  | Returns the L<Moose::Meta::Role> to which this attribute belongs, if any.
170 |  |  |  |  |
171 |  |  |  |  | =item B<< $attr->original_role >>
172 |  |  |  |  |
173 |  |  |  |  | Returns the L<Moose::Meta::Role> in which this attribute was first
174 |  |  |  |  | defined. This may not be the same as the value C<associated_role()> in the
175 |  |  |  |  | case of composite role, or the case where one role consumes other roles.
176 |  |  |  |  |
177 |  |  |  |  | =item B<< $attr->original_options >>
178 |  |  |  |  |
179 |  |  |  |  | Returns a hash reference of options passed to the constructor. This is used
180 |  |  |  |  | when creating a L<Moose::Meta::Attribute> object from this object.
181 |  |  |  |  |
182 |  |  |  |  | =item B<< $attr->attach_to_role($role) >>
183 |  |  |  |  |
184 |  |  |  |  | Attaches the attribute to the given L<Moose::Meta::Role>.
185 |  |  |  |  |
186 |  |  |  |  | =item B<< $attr->attribute_for_class($metaclass) >>
187 |  |  |  |  |
188 |  |  |  |  | Given an attribute metaclass name, this method calls C<<
189 |  |  |  |  | $metaclass->interpolate_class_and_new >> to construct an attribute object
190 |  |  |  |  | which can be added to a L<Moose::Meta::Class>.
191 |  |  |  |  |
192 |  |  |  |  | =item B<< $attr->clone >>
193 |  |  |  |  |
194 |  |  |  |  | Creates a new object identical to the object on which the method is called.
195 |  |  |  |  |
196 |  |  |  |  | =item B<< $attr->is_same_as($other_attr) >>
197 |  |  |  |  |
198 |  |  |  |  | Compares two role attributes and returns true if they are identical.
199 |  |  |  |  |

201 |  |  |  |  |
202 |  |  |  |  | In addition, this class implements all informational predicates implements by
203 |  |  |  |  | L<Moose::Meta::Attribute> (and L<Class::MOP::Attribute>).
