108 |  |  |  |  | =head1 NAME
109 |  |  |  |  |
110 |  |  |  |  | Class::MOP::Object - Base class for metaclasses
111 |  |  |  |  |
112 |  |  |  |  | =head1 VERSION
113 |  |  |  |  |
114 |  |  |  |  | version 2.0602
115 |  |  |  |  |
116 |  |  |  |  | =head1 DESCRIPTION
117 |  |  |  |  |
118 |  |  |  |  | This class is a very minimal base class for metaclasses.
119 |  |  |  |  |
120 |  |  |  |  | =head1 METHODS
121 |  |  |  |  |
122 |  |  |  |  | This class provides a few methods which are useful in all metaclasses.
123 |  |  |  |  |
124 |  |  |  |  | =over 4
125 |  |  |  |  |
126 |  |  |  |  | =item B<< Class::MOP::???->meta >>
127 |  |  |  |  |
128 |  |  |  |  | This returns a L<Class::MOP::Class> object.
129 |  |  |  |  |
130 |  |  |  |  | =item B<< $metaobject->dump($max_depth) >>
131 |  |  |  |  |
132 |  |  |  |  | This method uses L<Data::Dumper> to dump the object. You can pass an
133 |  |  |  |  | optional maximum depth, which will set C<$Data::Dumper::Maxdepth>. The
134 |  |  |  |  | default maximum depth is 1.
