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