metaclass - a pragma for installing and using Class::MOP metaclasses
version 2.2012
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';
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.
