Class::MOP::Method - Method Meta Object

version 2.2012

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.

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.
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.
