119 | |||||
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. | ||||

130 | |||||
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. | ||||
