120 | =head1 NAME | ||||
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. | ||||
