102 | # ABSTRACT: Base class for metaclasses | ||||
103 | |||||

106 | =pod | ||||
107 | |||||
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. | ||||
135 | |||||
