160 Moose::Object - The base object for Moose
164 This class is the default base class for all Moose-using classes. When
165 you C<use Moose> in this class, your class will inherit from this
168 It provides a default constructor and destructor, which run the
169 C<BUILDALL> and C<DEMOLISHALL> methods respectively.
171 You don't actually I<need> to inherit from this in order to use Moose,
172 but it makes it easier to take advantage of all of Moose's features.
178 =item B<< Moose::Object->new(%params) >>
180 This method calls C<< $class->BUILDARGS(@_) >>, and then creates a new
181 instance of the appropriate class. Once the instance is created, it
182 calls C<< $instance->BUILDALL($params) >>.
184 =item B<< Moose::Object->BUILDARGS(%params) >>
186 The default implementation of this method accepts a hash or hash
187 reference of named parameters. If it receives a single argument that
188 I<isn't> a hash reference it throws an error.
190 You can override this method in your class to handle other types of
191 options passed to the constructor.
193 This method should always return a hash reference of named options.
195 =item B<< $object->BUILDALL($params) >>
197 This method will call every C<BUILD> method in the inheritance
198 hierarchy, starting with the most distant parent class and ending with
201 The C<BUILD> method will be passed the hash reference returned by
204 =item B<< $object->DEMOLISHALL >>
206 This will call every C<DEMOLISH> method in the inheritance hierarchy,
207 starting with the object's class and ending with the most distant
208 parent. C<DEMOLISHALL> and C<DEMOLISH> will receive a boolean
209 indicating whether or not we are currently in global destruction.
211 =item B<< $object->does($role_name) >>
213 This returns true if the object does the given role.
215 =item B<DOES ($class_or_role_name)>
217 This is a a Moose role-aware implementation of L<UNIVERSAL/DOES>.
219 This is effectively the same as writing:
221 $object->does($name) || $object->isa($name)
223 This method will work with Perl 5.8, which did not implement
226 =item B<< $object->dump($maxdepth) >>
228 This is a handy utility for C<Data::Dumper>ing an object. By default,
229 the maximum depth is 1, to avoid making a mess.
