141 | |||||

144 | =pod | ||||
145 | |||||
146 | =head1 NAME | ||||
147 | |||||
148 | Moose::Meta::Method::Destructor - Method Meta Object for destructors | ||||
149 | |||||
150 | =head1 VERSION | ||||
151 | |||||
152 | version 2.0602 | ||||
153 | |||||
154 | =head1 DESCRIPTION | ||||
155 | |||||
156 | This class is a subclass of L<Class::MOP::Method::Inlined> that | ||||
157 | provides Moose-specific functionality for inlining destructors. | ||||
158 | |||||
159 | To understand this class, you should read the the | ||||
160 | L<Class::MOP::Method::Inlined> documentation as well. | ||||
161 | |||||
162 | =head1 INHERITANCE | ||||
163 | |||||
164 | C<Moose::Meta::Method::Destructor> is a subclass of | ||||
165 | L<Moose::Meta::Method> I<and> L<Class::MOP::Method::Inlined>. | ||||
166 | |||||
167 | =head1 METHODS | ||||
168 | |||||
169 | =over 4 | ||||
170 | |||||
171 | =item B<< Moose::Meta::Method::Destructor->new(%options) >> | ||||
172 | |||||
173 | This constructs a new object. It accepts the following options: | ||||
174 | |||||
175 | =over 8 | ||||
176 | |||||
177 | =item * package_name | ||||
178 | |||||
179 | The package for the class in which the destructor is being | ||||
180 | inlined. This option is required. | ||||
181 | |||||
182 | =item * name | ||||
183 | |||||
184 | The name of the destructor method. This option is required. | ||||
185 | |||||
186 | =item * metaclass | ||||
187 | |||||
188 | The metaclass for the class this destructor belongs to. This is | ||||
189 | optional, as it can be set later by calling C<< | ||||
190 | $metamethod->attach_to_class >>. | ||||
191 | |||||
192 | =back | ||||
193 | |||||
194 | =item B<< Moose::Meta;:Method::Destructor->is_needed($metaclass) >> | ||||
195 | |||||
196 | Given a L<Moose::Meta::Class> object, this method returns a boolean | ||||
197 | indicating whether the class needs a destructor. If the class or any | ||||
198 | of its parents defines a C<DEMOLISH> method, it needs a destructor. | ||||
199 | |||||

203 | |||||
204 | See L<Moose/BUGS> for details on reporting bugs. | ||||
