📝 DESCRIPTION

The Method Protocol is very small, since methods in Perl 5 are just subroutines in a specific package. We provide a very basic introspection interface.

🔧 METHODS

• Class::MOP::Method->wrap($code, %options) — This is the constructor. It accepts a method body in the form of either a code reference or a Class::MOP::Method instance, followed by a hash of options.

  The options are:

  • name — The method name (without a package name). This is required if $code is a coderef.
  • package_name — The package name for the method. This is required if $code is a coderef.
  • associated_metaclass — An optional Class::MOP::Class object. This is the metaclass for the method's class.
• $metamethod->clone(%params) — This makes a shallow clone of the method object. In particular, subroutine reference itself is shared between all clones of a given method. When a method is cloned, the original method object will be available by calling "original_method" on the clone.
• $metamethod->body — This returns a reference to the method's subroutine.
• $metamethod->name — This returns the method's name.
• $metamethod->package_name — This returns the method's package name.
• $metamethod->fully_qualified_name — This returns the method's fully qualified name (package name and method name).
• $metamethod->associated_metaclass — This returns the Class::MOP::Class object for the method, if one exists.
• $metamethod->original_method — If this method object was created as a clone of some other method object, this returns the object that was cloned.
• $metamethod->original_name — This returns the method's original name, wherever it was first defined. If this method is a clone of a clone (of a clone, etc.), this method returns the name from the first method in the chain of clones.
• $metamethod->original_package_name — This returns the method's original package name, wherever it was first defined. If this method is a clone of a clone (of a clone, etc.), this method returns the package name from the first method in the chain of clones.
• $metamethod->original_fully_qualified_name — This returns the method's original fully qualified name, wherever it was first defined. If this method is a clone of a clone (of a clone, etc.), this method returns the fully qualified name from the first method in the chain of clones.
• $metamethod->is_stub — Returns true if the method is just a stub:

  sub foo;

• $metamethod->attach_to_class($metaclass) — Given a Class::MOP::Class object, this method sets the associated metaclass for the method. This will overwrite any existing associated metaclass.
• $metamethod->detach_from_class — Removes any associated metaclass object for the method.
• $metamethod->execute(...) — This executes the method. Any arguments provided will be passed on to the method itself.
• Class::MOP::Method->meta — This will return a Class::MOP::Class instance for this class. It should also be noted that Class::MOP will actually bootstrap this module by installing a number of attribute meta-objects into its metaclass.
