150 | =head1 DESCRIPTION |
151 | |
152 | Moose. |
153 | |
154 | =head1 INTERFACE |
155 | |
306290e8 |
156 | =head2 meta -> Mouse::Meta::Class |
c3398f5b |
157 | |
158 | Returns this class' metaclass instance. |
159 | |
160 | =head2 extends superclasses |
161 | |
162 | Sets this class' superclasses. |
163 | |
164 | =head2 has (name|names) => parameters |
165 | |
166 | Adds an attribute (or if passed an arrayref of names, multiple attributes) to |
167 | this class. |
168 | |
169 | =head2 confess error -> BOOM |
170 | |
171 | L<Carp/confess> for your convenience. |
172 | |
173 | =head2 blessed value -> ClassName | undef |
174 | |
175 | L<Scalar::Util/blessed> for your convenience. |
176 | |
177 | =head1 MISC |
178 | |
179 | =head2 import |
180 | |
6caea456 |
181 | Importing Mouse will default your class' superclass list to L<Mouse::Object>. |
c3398f5b |
182 | You may use L</extends> to replace the superclass list. |
183 | |
184 | =head2 unimport |
185 | |
186 | Please unimport Mouse so that if someone calls one of the keywords (such as |
187 | L</extends>) it will break loudly instead breaking subtly. |
188 | |
189 | =head1 FUNCTIONS |
190 | |
191 | =head2 load_class Class::Name |
192 | |
6caea456 |
193 | This will load a given C<Class::Name> (or die if it's not loadable). |
c3398f5b |
194 | This function can be used in place of tricks like |
195 | C<eval "use $module"> or using C<require>. |
