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. You don't actually I<need> to inherit from this in order to use Moose though. It is just here to make life easier. =head1 METHODS =over 4 =item B<meta> This will return the metaclass associated with the given class. =item B<new> This will call C<BUILDARGS>, create a new instance and call C<BUILDALL>. =item B<BUILDARGS> This method processes an argument list into a hash reference. It is used by C<new>. =item B<BUILDALL> 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<DEMOLISHALL> This will call every C<DEMOLISH> method in the inheritance hierarchy. =item B<does ($role_name)> This will check if the invocant's class C<does> a given C<$role_name>. This is similar to C<isa> for object, but it checks the roles instead. =item B<DOES ($class_or_role_name)> A Moose Role aware implementation of L<UNIVERSAL/DOES>. C<DOES> is equivalent to C<isa> or C<does>. =item B<dump ($maxdepth)> C'mon, how many times have you written the following code while debugging: use Data::Dumper; warn Dumper $obj; It can get seriously annoying, so why not just use this. =back =head1 BUGS All complex software has bugs lurking in it, and this module is no exception. If you find a bug please either email me, or add the bug to cpan-RT. =head1 AUTHOR Stevan Little E<lt>stevan@iinteractive.comE<gt> =head1 COPYRIGHT AND LICENSE Copyright 2006-2009 by Infinity Interactive, Inc.
