Public Class Methods

from_module(class_type, mod) click to toggle source

Return a RDoc::ClassModule of class class_type that is a copy of module module. Used to promote modules to classes.

end
            
new(name, superclass = nil) click to toggle source

Creates a new ClassModule with name with optional superclass

This is a constructor for subclasses, and must never be called directly.

 
               # File rdoc/class_module.rb, line 101
def initialize(name, superclass = nil)
  @constant_aliases = []
  @diagram          = nil
  @is_alias_for     = nil
  @name             = name
  @superclass       = superclass
  @comment_location = [] # [[comment, location]]

  super()
end
            

Public Instance Methods

add_comment(comment, location) click to toggle source

Adds comment to this ClassModule’s list of comments at location. This method is preferred over comment= since it allows ri data to be updated across multiple runs.

 
               # File rdoc/class_module.rb, line 117
def add_comment comment, location
  return if comment.empty? or not document_self

  original = comment

  comment = normalize_comment comment
  @comment_location << [comment, location]

  self.comment = original
end
            
ancestors() click to toggle source

Ancestors list for this ClassModule: the list of included modules (classes will add their superclass if any).

Returns the included classes or modules, not the includes themselves. The returned values are either String or RDoc::NormalModule instances (see RDoc::Include#module).

The values are returned in reverse order of their inclusion, which is the order suitable for searching methods/attributes in the ancestors. The superclass, if any, comes last.

 
               # File rdoc/class_module.rb, line 140
def ancestors
  includes.map { |i| i.module }.reverse
end
            
clear_comment() click to toggle source

Clears the comment. Used by the ruby parser.

 
               # File rdoc/class_module.rb, line 147
def clear_comment
  @comment = ''
end
            
comment=(comment) click to toggle source

This method is deprecated, use add_comment instead.

Appends comment to the current comment, but separated by a rule. Works more like +=.

 
               # File rdoc/class_module.rb, line 157
def comment= comment
  return if comment.empty?

  comment = normalize_comment comment
  comment = "#{@comment}\n---\n#{comment}" unless @comment.empty?

  super comment
end
            
complete(min_visibility) click to toggle source

Prepares this ClassModule for use by a generator.

See RDoc::TopLevel.complete

 
               # File rdoc/class_module.rb, line 171
def complete min_visibility
  update_aliases
  remove_nodoc_children
  update_includes
  remove_invisible min_visibility
end
            
each_ancestor() click to toggle source

Iterates the ancestors of this class or module for which an RDoc::ClassModule exists.

 
               # File rdoc/class_module.rb, line 182
def each_ancestor # :yields: module
  ancestors.each do |mod|
    next if String === mod
    yield mod
  end
end
            
find_ancestor_local_symbol(symbol) click to toggle source

Looks for a symbol in the ancestors. See Context#find_local_symbol.

 
               # File rdoc/class_module.rb, line 192
def find_ancestor_local_symbol symbol
  each_ancestor do |m|
    res = m.find_local_symbol(symbol)
    return res if res
  end

  nil
end
            
find_class_named(name) click to toggle source

Finds a class or module with name in this namespace or its descendants

 
               # File rdoc/class_module.rb, line 204
def find_class_named name
  return self if full_name == name
  return self if @name == name

  @classes.values.find do |klass|
    next if klass == self
    klass.find_class_named name
  end
end
            
full_name() click to toggle source

Return the fully qualified name of this class or module

 
               # File rdoc/class_module.rb, line 217
def full_name
  @full_name ||= if RDoc::ClassModule === @parent then
                   "#{@parent.full_name}::#{@name}"
                 else
                   @name
                 end
end
            
merge(class_module) click to toggle source

Merges class_module into this ClassModule.

The data in class_module is preferred over the receiver.

 
               # File rdoc/class_module.rb, line 323
def merge class_module
  other_document = parse class_module.comment_location

  if other_document then
    document = parse @comment_location

    document = document.merge other_document

    @comment = @comment_location = document
  end

  cm = class_module
  other_files = cm.in_files

  merge_collections attributes, cm.attributes, other_files do |add, attr|
    if add then
      add_attribute attr
    else
      @attributes.delete attr

    end
  end

  merge_collections includes, cm.includes, other_files do |add, incl|
    if add then
      add_include incl
    else
      @includes.delete incl
    end
  end

  merge_collections method_list, cm.method_list, other_files do |add, meth|
    if add then
      add_method meth
    else
      @method_list.delete meth
      @methods_hash.delete meth.pretty_name
    end
  end

  self
end
            
module?() click to toggle source

def module?
  false
end
            
name=(new_name) click to toggle source

Allows overriding the initial name.

Used for modules and classes that are constant aliases.

 
               # File rdoc/class_module.rb, line 426
def name= new_name
  @name = new_name
end
            
name_for_path() click to toggle source

Name to use to generate the url: modules and classes that are aliases for another module or class return the name of the latter.

 
               # File rdoc/class_module.rb, line 465
def name_for_path
  is_alias_for ? is_alias_for.full_name : full_name
end
            
non_aliases() click to toggle source

Returns the classes and modules that are not constants aliasing another class or module. For use by formatters only (caches its result).

 
               # File rdoc/class_module.rb, line 474
def non_aliases
  @non_aliases ||= classes_and_modules.reject { |cm| cm.is_alias_for }
end
            
parse(comment_location) click to toggle source

Parses comment_location into an RDoc::Markup::Document composed of multiple RDoc::Markup::Documents with their file set.

 
               # File rdoc/class_module.rb, line 434
def parse comment_location
  case comment_location
  when String then
    super
  when Array then
    docs = comment_location.map do |comment, location|
      doc = super comment
      doc.file = location.absolute_name
      doc
    end

    RDoc::Markup::Document.new(*docs)
  when RDoc::Markup::Document then
    return comment_location
  else
    raise ArgumentError, "unknown comment class #{comment_location.class}"
  end
end
            
path() click to toggle source

Path to this class or module

 
               # File rdoc/class_module.rb, line 456
def path
  http_url RDoc::RDoc.current.generator.class_dir
end
            
remove_nodoc_children() click to toggle source

Updates the child modules or classes of class/module parent by deleting the ones that have been removed from the documentation.

parent_hash is either parent.modules_hash or parent.classes_hash and all_hash is ::all_modules_hash or ::all_classes_hash.

 
               # File rdoc/class_module.rb, line 486
def remove_nodoc_children
  prefix = self.full_name + '::'

  modules_hash.each_key do |name|
    full_name = prefix + name
    modules_hash.delete name unless RDoc::TopLevel.all_modules_hash[full_name]
  end

  classes_hash.each_key do |name|
    full_name = prefix + name
    classes_hash.delete name unless RDoc::TopLevel.all_classes_hash[full_name]
  end
end
            
superclass() click to toggle source

Get the superclass of this class. Attempts to retrieve the superclass object, returns the name if it is not known.

 
               # File rdoc/class_module.rb, line 504
def superclass
  RDoc::TopLevel.find_class_named(@superclass) || @superclass
end
            
superclass=(superclass) click to toggle source

Set the superclass of this class to superclass

 
               # File rdoc/class_module.rb, line 511
def superclass=(superclass)
  raise NoMethodError, "#{full_name} is a module" if module?
  @superclass = superclass
end
            
type() click to toggle source

‘module’ or ‘class’

 
               # File rdoc/class_module.rb, line 527
def type
  module? ? 'module' : 'class'
end
            
update_aliases() click to toggle source

Updates the child modules & classes by replacing the ones that are aliases through a constant.

The aliased module/class is replaced in the children and in RDoc::TopLevel.all_modules_hash or RDoc::TopLevel.all_classes_hash by a copy that has RDoc::ClassModule#is_alias_for set to the aliased module/class, and this copy is added to #aliases of the aliased module/class.

Formatters can use the non_aliases method to retrieve children that are not aliases, for instance to list the namespace content, since the aliased modules are included in the constants of the class/module, that are listed separately.

 
               # File rdoc/class_module.rb, line 546
def update_aliases
  constants.each do |const|
    next unless cm = const.is_alias_for
    cm_alias = cm.dup
    cm_alias.name = const.name
    cm_alias.parent = self
    cm_alias.full_name = nil  # force update for new parent
    cm_alias.aliases.clear
    cm_alias.is_alias_for = cm

    if cm.module? then
      RDoc::TopLevel.all_modules_hash[cm_alias.full_name] = cm_alias
      modules_hash[const.name] = cm_alias
    else
      RDoc::TopLevel.all_classes_hash[cm_alias.full_name] = cm_alias
      classes_hash[const.name] = cm_alias
    end

    cm.aliases << cm_alias
  end
end
            
update_includes() click to toggle source

Deletes from includes those whose module has been removed from the documentation.

 
               # File rdoc/class_module.rb, line 574
def update_includes
  includes.reject! do |include|
    mod = include.module
    !(String === mod) && RDoc::TopLevel.all_modules_hash[mod.full_name].nil?
  end
end
