131=head1 NAME
132
133Moose::Meta::Method::Destructor - Method Meta Object for destructors
134
135=head1 DESCRIPTION
136
137This class is a subclass of L<Class::MOP::Class::Generated> that
138provides Moose-specific functionality for inlining destructors.
139
140To understand this class, you should read the the
141L<Class::MOP::Class::Generated> documentation as well.
142
143=head1 INHERITANCE
144
145C<Moose::Meta::Method::Destructor> is a subclass of
146L<Moose::Meta::Method> I<and> L<Class::MOP::Method::Generated>.
147
148=head1 METHODS
149
150=over 4
151
152=item B<< Moose::Meta::Method::Destructor->new(%options) >>
153
154This constructs a new object. It accepts the following options:
155
156=over 8
157
158=item * package_name
159
160The package for the class in which the destructor is being
161inlined. This option is required.
162
163=item * name
164
165The name of the destructor method. This option is required.
166
167=item * metaclass
168
169The metaclass for the class this destructor belongs to. This is
170optional, as it can be set later by calling C<<
171$metamethod->attach_to_class >>.
172
173=back
174
175=item B<< Moose::Meta;:Method::Destructor->is_needed($metaclass) >>
176
177Given a L<Moose::Meta::Class> object, this method returns a boolean
178indicating whether the class needs a destructor. If the class or any
179of its parents defines a C<DEMOLISH> method, it needs a destructor.
