| 121 | |||||
| 122 | Class::MOP::Method::Inlined - Method base class for methods which have been inlined | ||||
| 123 | |||||
| 124 | =head1 VERSION | ||||
| 125 | |||||
| 126 | version 2.0602 | ||||
| 127 | |||||
| 128 | =head1 DESCRIPTION | ||||
| 129 | |||||
| 130 | This is a L<Class::MOP::Method::Generated> subclass for methods which | ||||
| 131 | can be inlined. | ||||
| 132 | |||||
| 133 | =head1 METHODS | ||||
| 134 | |||||
| 135 | =over 4 | ||||
| 136 | |||||
| 137 | =item B<< $metamethod->can_be_inlined >> | ||||
| 138 | |||||
| 139 | This method returns true if the method in question can be inlined in | ||||
| 140 | the associated metaclass. | ||||
| 141 | |||||
| 142 | If it cannot be inlined, it spits out a warning and returns false. | ||||
