| 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 | |||||
