150 Moose::Object - The base object for Moose
154 This class is the default base class for all Moose-using classes. When
155 you C<use Moose> in this class, your class will inherit from this
158 It provides a default constructor and destructor, which run the
159 C<BUILDALL> and C<DEMOLISHALL> methods respectively.
161 You don't actually I<need> to inherit from this in order to use Moose,
162 but it makes it easier to take advantage of all of Moose's features.
168 =item B<< Moose::Object->new(%params) >>
170 This method calls C<< $class->BUILDARGS(@_) >>, and then creates a new
171 instance of the appropriate class. Once the instance is created, it
172 calls C<< $instance->BUILDALL($params) >>.
174 =item B<< Moose::Object->BUILDARGS(%params) >>
176 The default implementation of this method accepts a hash or hash
177 reference of named parameters. If it receives a single argument that
178 I<isn't> a hash reference it throws an error.
180 You can override this method in your class to handle other types of
181 options passed to the constructor.
183 This method should always return a hash reference of named options.
185 =item B<< $object->BUILDALL($params) >>
187 This method will call every C<BUILD> method in the inheritance
188 hierarchy, starting with the most distant parent class and ending with
191 The C<BUILD> method will be passed the hash reference returned by
194 =item B<< $object->DEMOLISHALL >>
196 This will call every C<DEMOLISH> method in the inheritance hierarchy,
197 starting with the object's class and ending with the most distant
198 parent. C<DEMOLISHALL> and C<DEMOLISH> will receive a boolean
199 indicating whether or not we are currently in global destruction.
201 =item B<< $object->does($role_name) >>
203 This returns true if the object does the given role.
205 =item B<DOES ($class_or_role_name)>
207 This is a a Moose role-aware implementation of L<UNIVERSAL/DOES>.
209 This is effectively the same as writing:
211 $object->does($name) || $object->isa($name)
213 This method will work with Perl 5.8, which did not implement
216 =item B<< $object->dump($maxdepth) >>
218 This is a handy utility for C<Data::Dumper>ing an object. By default,
219 the maximum depth is 1, to avoid making a mess.
