Object
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 }
The RDoc::RDoc driver for this parse tree. This allows classes consulting the documentation tree to access user-set options, for example.
Creates a new Store of type that will load or save to path

Adds module as an enclosure (namespace) for the given variable for C files.
# File rdoc/store.rb, line 169
def add_c_enclosure variable, namespace
@c_enclosure_classes[variable] = namespace
end
Adds C variables from an RDoc::Parser::C
# File rdoc/store.rb, line 176

filename = c_parser.top_level.relative_name
@c_class_variables[filename] = make_variable_map c_parser.classes
@c_singleton_class_variables[filename] = c_parser.singleton_classes
end
Adds the file with name as an RDoc::TopLevel to the store. Returns the created RDoc::TopLevel.

Ancestors cache accessor. Maps a klass name to an Array of its ancestors in this store. If Foo in this store inherits from Object, Kernel won't be listed (it will be included from ruby's ri store).

Class methods cache accessor. Maps a class to an Array of its class methods (not full name).
# File rdoc/store.rb, line 269

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 RDoc::ClassModule#is_alias_for set.
It updates the RDoc::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.

Fixes the erroneous BasicObject < Object in 1.9.

We fix BasicObject right away if we are running in a Ruby version >= 1.9.
