Overview

A set of rdoc data for a single project (gem, path, etc.).

The store manages reading and writing ri data for a project and maintains a cache of methods, classes and ancestors in the store.

The store maintains a #cache of its contents for faster lookup. After adding items to the store it must be flushed using #save_cache. The cache contains the following structures:

@cache = {
  :ancestors        => {}, # class name => ancestor names
  :attributes       => {}, # class name => attributes
  :class_methods    => {}, # class name => class methods
  :instance_methods => {}, # class name => instance methods
  :modules          => [], # classes and modules in this store
  :pages            => [], # page names
}

    #complete(min_visibility)  
  



  

    

Prepares the RDoc code object tree for use by a generator.



It finds unique classes/modules defined, and replaces classes/modules that are aliases for another one by a copy with ClassModule#is_alias_for set.



It updates the ClassModule#constant_aliases attribute of “real” classes or modules.



It also completely removes the classes and modules that should be removed from the documentation and the methods that have a visibility below min_visibility, which is the --visibility option.
