Overview

A Context is something that can hold modules, classes, methods, attributes, aliases, requires, and includes. Classes, modules, and files are all Contexts.

Adds attribute if not already there. If it is (as method(s) or attribute), updates the comment if it was empty.

The attribute is registered only if it defines a new method. For instance, attr_reader :foo will not be registered if method foo exists, but attr_accessor :foo will be registered if method foo exists, but foo= does not.

#add_class(class_type, given_name, superclass = '::Object')

Adds a class named given_name with superclass.

Both given_name and superclass may contain '::', and are interpreted relative to the self context. This allows handling correctly examples like these:

class RDoc::Gauntlet < Gauntlet
module Mod
  class Object   # implies < ::Object
  class SubObject < Object  # this is _not_ ::Object

Given class Container::Item RDoc assumes Container is a module unless it later sees class Container. add_class automatically upgrades given_name to a class in this case.
