- =head1 NAME
-
- Moose::Object - The base object for Moose
-
- =head1 DESCRIPTION
-
- This class is the default base class for all Moose-using classes. When
- you C<use Moose> in this class, your class will inherit from this
- class.
-
- It provides a default constructor and destructor, which run the
- C<BUILDALL> and C<DEMOLISHALL> methods respectively.
-
- You don't actually I<need> to inherit from this in order to use Moose,
- but it makes it easier to take advantage of all of Moose's features.
-
- =head1 METHODS
-
- =over 4
-
- =item B<< Moose::Object->new(%params) >>
-
- This method calls C<< $class->BUILDARGS(@_) >>, and then creates a new
- instance of the appropriate class. Once the instance is created, it
- calls C<< $instance->BUILDALL($params) >>.
-
- =item B<< Moose::Object->BUILDARGS(%params) >>
-
- The default implementation of this method accepts a hash or hash
- reference of named parameters. If it receives a single argument that
- I<isn't> a hash reference it throws an error.
-
- You can override this method in your class to handle other types of
- options passed to the constructor.
-
- This method should always return a hash reference of named options.
-
- =item B<< $object->BUILDALL($params) >>
-
- This method will call every C<BUILD> method in the inheritance
- hierarchy, starting with the most distant parent class and ending with
- the object's class.
-
- The C<BUILD> method will be passed the hash reference returned by
- C<BUILDARGS>.
-
- =item B<< $object->DEMOLISHALL >>
-
- This will call every C<DEMOLISH> method in the inheritance hierarchy,
- starting with the object's class and ending with the most distant
- parent. C<DEMOLISHALL> and C<DEMOLISH> will receive a boolean
- indicating whether or not we are currently in global destruction.
-
- =item B<< $object->does($role_name) >>
-
- This returns true if the object does the given role.
-
- =item B<DOES ($class_or_role_name)>
-
- This is a a Moose role-aware implementation of L<UNIVERSAL/DOES>.
-
- This is effectively the same as writing:
-
- $object->does($name) || $object->isa($name)
-
- This method will work with Perl 5.8, which did not implement
- C<UNIVERSAL::DOES>.
-
- =item B<< $object->dump($maxdepth) >>
-
- This is a handy utility for C<Data::Dumper>ing an object. By default,
- the maximum depth is 1, to avoid making a mess.
