110 Class::MOP::Method - Method Meta Object
114 The Method Protocol is very small, since methods in Perl 5 are just
115 subroutines within the particular package. We provide a very basic
116 introspection interface.
126 This will return a B<Class::MOP::Class> instance which is related
135 =item B<wrap ($code, %params)>
137 This is the basic constructor, it returns a B<Class::MOP::Method>
138 instance which wraps the given C<$code> reference. You can also
139 set the C<package_name> and C<name> attributes using the C<%params>.
140 If these are not set, then thier accessors will attempt to figure
141 it out using the C<Class::MOP::get_code_info> function.
143 =item B<clone (%params)>
145 This will make a copy of the object, allowing you to override
146 any values by stuffing them in C<%params>.
156 This returns the actual CODE reference of the particular instance.
160 This returns the name of the CODE reference.
162 =item B<associated_metaclass>
164 The metaclass of the method
166 =item B<package_name>
168 This returns the package name that the CODE reference is attached to.
170 =item B<fully_qualified_name>
172 This returns the fully qualified name of the CODE reference.
180 =item B<attach_to_class>
182 Sets the associated metaclass
184 =item B<detach_from_class>
186 Disassociates the method from the metaclass
