# metaclass(3pm)

a pragma for installing and using Class::MOP metaclasses

## NAME

metaclass - a pragma for installing and using Class::MOP metaclasses

## VERSION

version 2.4001

## SYNOPSIS

```
  package MyClass;
  # use Class::MOP::Class
  use metaclass;
  # ... or use a custom metaclass
  use metaclass 'MyMetaClass';
  # ... or use a custom metaclass
  # and custom attribute and method
  # metaclasses
  use metaclass 'MyMetaClass' => (
      'attribute_metaclass' => 'MyAttributeMetaClass',
      'method_metaclass'    => 'MyMethodMetaClass',
  );
  # ... or just specify custom attribute
  # and method classes, and Class::MOP::Class
  # is the assumed metaclass
  use metaclass (
      'attribute_metaclass' => 'MyAttributeMetaClass',
      'method_metaclass'    => 'MyMethodMetaClass',
  );
  # if we'd rather not install a 'meta' method, we can do this
  use metaclass meta_name => undef;
  # or if we'd like it to have a different name,
  use metaclass meta_name => 'my_meta';
```

## DESCRIPTION

This is a pragma to make it easier to use a specific metaclass and a set of custom attribute and method metaclasses. It also installs a `"meta"` method to your class as well, unless `"undef"` is passed to the `"meta_name"` option.

Note that if you are using Moose, you most likely do **not** want to be using this - look into Moose::Util::MetaRole instead.
