128=head1 NAME
129
130Moose::Meta::Method::Destructor - Method Meta Object for destructors
131
132=head1 DESCRIPTION
133
134This class is a subclass of L<Class::MOP::Class::Generated> that
135provides Moose-specific functionality for inlining destructors.
136
137To understand this class, you should read the the
138L<Class::MOP::Class::Generated> documentation as well.
139
140=head1 INHERITANCE
141
142C<Moose::Meta::Method::Destructor> is a subclass of
143L<Moose::Meta::Method> I<and> L<Class::MOP::Method::Generated>.
144
145=head1 METHODS
146
147=over 4
148
149=item B<< Moose::Meta;:Method::Destructor->new(%options) >>
150
151This constructs a new object. It accepts the following options:
152
153=over 8
154
155=item * package_name
156
157The package for the class in which the destructor is being
158inlined. This option is required.
159
160=item * name
161
162The name of the destructor method. This option is required.
163
164=item * metaclass
165
166The metaclass for the class this destructor belongs to. This is
167optional, as it can be set later by calling C<<
168$metamethod->attach_to_class >>.
169
170=back
171
172=item B<< Moose::Meta;:Method::Destructor->is_needed($metaclass) >>
173
174Given a L<Moose::Meta::Class> object, this method returns a boolean
175indicating whether the class needs a destructor. If the class or any
176of its parents defines a C<DEMOLISH> method, it needs a destructor.
