NAME

Class::MOP::Immutable - A class to transform Class::MOP::Class metaclasses

SYNOPSIS

     use Class::MOP::Immutable;
 
     my $immutable_metaclass = Class::MOP::Immutable->new($metaclass, {
         read_only   => [qw/superclasses/],
         cannot_call => [qw/
             add_method
             alias_method
             remove_method
             add_attribute
             remove_attribute
             add_package_symbol
             remove_package_symbol
         /],
         memoize     => {
             class_precedence_list             => 'ARRAY',
             compute_all_applicable_attributes => 'ARRAY',
             get_meta_instance                 => 'SCALAR',
             get_method_map                    => 'SCALAR',
         }
     });
 
     $immutable_metaclass->make_metaclass_immutable(@_)
 
 

DESCRIPTION

This is basically a module for applying a transformation on a given metaclass. Current features include making methods read-only, making methods un-callable and memoizing methods (in a type specific way too).

This module is not for the feint of heart, it does some whacky things to the metaclass in order to make it immutable. If you are just curious, I suggest you turn back now, there is nothing to see here.

METHODS

new ($metaclass, \%options)

Given a $metaclass and a set of %options this module will prepare an immutable version of the $metaclass, which can then be applied to the $metaclass using the "make_metaclass_immutable" method.

options

Returns the options HASH set in "new".

metaclass

Returns the metaclass set in "new".

immutable_metaclass

Returns the immutable metaclass created within "new".

create_immutable_metaclass

This will create the immutable version of the $metaclass, but will not actually change the original metaclass.

create_methods_for_immutable_metaclass

This will create all the methods for the immutable metaclass based on the %options passed into "new".

make_metaclass_immutable (%options)

This will actually change the $metaclass into the immutable version.

make_metaclass_mutable (%options)

This will change the $metaclass into the mutable version by reversing the immutable process. %options should be the same options that were given to make_metaclass_immutable.

inlined_constructor

If the constructor was inlined, this returns the constructor method object that was created to do this.
