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