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