This utility module is designed to help authors of Moose extensions write extensions that are able to cooperate with other Moose extensions. To do this, you must write your extensions as roles, which can then be dynamically applied to the caller's metaclasses.
This module makes sure to preserve any existing superclasses and roles already set for the meta objects, which means that any number of extensions can apply roles in any order.
The easiest way to use this module is through the Moose::Exporter manpage, which can
generate the appropriate init_meta
method for you, and make sure it is
called when imported.
This module provides two functions.
This function will apply roles to one or more metaclasses for the specified class. It will return a new metaclass object for the class or role passed in the ``for'' parameter.
It accepts the following parameters:
Each key should in turn point to an array reference of role names.
It accepts the following keys:
It accepts the following keys:
This function will apply the specified roles to the object's base class.
