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