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