=head1 DESCRIPTION
-This serves as the base object for all Moose classes. Every
-effort will be made to ensure that all classes which C<use Moose>
-will inherit from this class. It provides a default constructor
-and destructor, which run all the BUILD and DEMOLISH methods in
-the class tree.
+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 though. It is just here to make life easier.
+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<meta>
+=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 will return the metaclass associated with the given class.
+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.
-=item B<new>
+The C<BUILD> method will be passed the hash reference returned by
+C<BUILDARGS>.
-This will create a new instance and call C<BUILDALL>.
+=item B<< $object->DEMOLISHALL >>
-=item B<BUILDALL>
+This will call every C<DEMOLISH> method in the inheritance hierarchy,
+starting with the object's class and ending with the most distant
+parent.
-This will call every C<BUILD> method in the inheritance hierarchy,
-and pass it a hash-ref of the the C<%params> passed to C<new>.
+=item B<< $object->does($role_name) >>
-=item B<DEMOLISHALL>
+This returns true if the object does the given role.
-This will call every C<DEMOLISH> method in the inheritance hierarchy.
+=item B<DOES ($class_or_role_name)>
-=item B<does ($role_name)>
+This is a a Moose role-aware implementation of L<UNIVERSAL/DOES>.
-This will check if the invocant's class C<does> a given C<$role_name>.
-This is similar to C<isa> for object, but it checks the roles instead.
+This is effectively the same as writing:
-=item B<dump ($maxdepth)>
+ $object->does($name) || $object->isa($name)
-Cmon, how many times have you written the following code while debugging:
+This method will work with Perl 5.8, which did not implement
+C<UNIVERSAL::DOES>.
- use Data::Dumper;
- warn Dumper $obj;
+=item B<< $object->dump($maxdepth) >>
-It can get seriously annoying, so why not just use this.
+This is a handy utility for C<Data::Dumper>ing an object. By default,
+the maximum depth is 1, to avoid making a mess.
