| 120 | Class::MOP::Method::Inlined - Method base class for methods which have been inlined | ||||
| 121 | |||||
| 122 | =head1 DESCRIPTION | ||||
| 123 | |||||
| 124 | This is a L<Class::MOP::Method::Generated> subclass for methods which | ||||
| 125 | can be inlined. | ||||

| 131 | =item B<< $metamethod->can_be_inlined >> | ||||
| 132 | |||||
| 133 | This method returns true if the method in question can be inlined in | ||||
| 134 | the associated metaclass. | ||||
| 135 | |||||
| 136 | If it cannot be inlined, it spits out a warning and returns false. | ||||
