end

#include_in_class(klass_, include_ancestry_ = false) ⇒ Object

A class that implements this type should call this method to get the appropriate mixins. If include_ancestry_ is set to true, then mixins connected to subtypes of this type are also added to the class.

#include_in_object(obj_, include_ancestry_ = false) ⇒ Object

An object that implements this type should call this method to get the appropriate mixins. If include_ancestry_ is set to true, then mixins connected to subtypes of this type are also added to the object.
