111 Class::MOP::Method - Method Meta Object
115 The Method Protocol is very small, since methods in Perl 5 are just
116 subroutines within the particular package. We provide a very basic
117 introspection interface.
127 This will return a B<Class::MOP::Class> instance which is related
136 =item B<wrap ($code, %params)>
138 This is the basic constructor, it returns a B<Class::MOP::Method>
139 instance which wraps the given C<$code> reference. You can also
140 set the C<package_name> and C<name> attributes using the C<%params>.
141 If these are not set, then thier accessors will attempt to figure
142 it out using the C<Class::MOP::get_code_info> function.
144 =item B<clone (%params)>
146 This will make a copy of the object, allowing you to override
147 any values by stuffing them in C<%params>.
157 This returns the actual CODE reference of the particular instance.
161 This returns the name of the CODE reference.
163 =item B<associated_metaclass>
165 The metaclass of the method
167 =item B<package_name>
169 This returns the package name that the CODE reference is attached to.
171 =item B<fully_qualified_name>
173 This returns the fully qualified name of the CODE reference.
181 =item B<attach_to_class>
183 Sets the associated metaclass
185 =item B<detach_from_class>
187 Disassociates the method from the metaclass
