131 # ABSTRACT: The base object for Moose
139 This class is the default base class for all Moose-using classes. When
140 you C<use Moose> in this class, your class will inherit from this
143 It provides a default constructor and destructor, which run the
144 C<BUILDALL> and C<DEMOLISHALL> methods respectively.
146 You don't actually I<need> to inherit from this in order to use Moose,
147 but it makes it easier to take advantage of all of Moose's features.
153 =item B<< Moose::Object->new(%params) >>
155 This method calls C<< $class->BUILDARGS(@_) >>, and then creates a new
156 instance of the appropriate class. Once the instance is created, it
157 calls C<< $instance->BUILDALL($params) >>.
159 =item B<< Moose::Object->BUILDARGS(%params) >>
161 The default implementation of this method accepts a hash or hash
162 reference of named parameters. If it receives a single argument that
163 I<isn't> a hash reference it throws an error.
165 You can override this method in your class to handle other types of
166 options passed to the constructor.
168 This method should always return a hash reference of named options.
170 =item B<< $object->BUILDALL($params) >>
172 This method will call every C<BUILD> method in the inheritance
173 hierarchy, starting with the most distant parent class and ending with
176 The C<BUILD> method will be passed the hash reference returned by
179 =item B<< $object->DEMOLISHALL >>
181 This will call every C<DEMOLISH> method in the inheritance hierarchy,
182 starting with the object's class and ending with the most distant
183 parent. C<DEMOLISHALL> and C<DEMOLISH> will receive a boolean
184 indicating whether or not we are currently in global destruction.
186 =item B<< $object->does($role_name) >>
188 This returns true if the object does the given role.
190 =item B<DOES ($class_or_role_name)>
192 This is a a Moose role-aware implementation of L<UNIVERSAL/DOES>.
194 This is effectively the same as writing:
196 $object->does($name) || $object->isa($name)
198 This method will work with Perl 5.8, which did not implement
201 =item B<< $object->dump($maxdepth) >>
203 This is a handy utility for C<Data::Dumper>ing an object. By default,
204 the maximum depth is 1, to avoid making a mess.
210 See L<Moose/BUGS> for details on reporting bugs.
