# A module describes the capabilities of a group of objects, ie what data it has # and functions it responds to. # The group may be a Class, but a module may be included into classes and objects too. # # The class also keeps a list of class methods (with names+code) # Class methods are instance methods on the class object # So it is essential that the class (the object defining the class) # can carry methods. It does so as instance variables. # In fact this property is implemented in the Object, as methods # may be added to any object at run-time module Parfait class Module < Object # :<, :<=, :>, :>=, :included_modules, :include?, :name, :ancestors, :instance_methods, :public_instance_methods, # :protected_instance_methods, :private_instance_methods, :constants, :const_get, :const_set, :const_defined?, # :const_missing, :class_variables, :remove_class_variable, :class_variable_get, :class_variable_set, # :class_variable_defined?, :public_constant, :private_constant, :singleton_class?, :include, :prepend, # :module_exec, :class_exec, :module_eval, :class_eval, :method_defined?, :public_method_defined?, # :private_method_defined?, :protected_method_defined?, :public_class_method, :private_class_method, :autoload, # :autoload?, :instance_method, :public_instance_method end end
