new(name, superclass = nil)

Creates a new ClassModule with name with optional superclass

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

# File ../ruby/lib/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
Instance Public methods
add_comment(comment, location)

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.

Source: show | on GitHub 

# File ../ruby/lib/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()

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.

Source: show | on GitHub 

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

Clears the comment. Used by the ruby parser.

Source: show | on GitHub 

# File ../ruby/lib/rdoc/class_module.rb, line 147
def clear_comment
  @comment = ''
end
comment=(comment)

This method is deprecated, use add_comment instead.

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

Source: show | on GitHub 

# File ../ruby/lib/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)

Prepares this ClassModule for use by a generator.

See RDoc::TopLevel.complete

Source: show | on GitHub 

# File ../ruby/lib/rdoc/class_module.rb, line 171
def complete min_visibility
  update_aliases
  remove_nodoc_children
  update_includes
  remove_invisible min_visibility
end
each_ancestor()

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

Source: show | on GitHub 

# File ../ruby/lib/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)

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

Source: show | on GitHub 

# File ../ruby/lib/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)

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

Source: show | on GitHub 

# File ../ruby/lib/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()

                   "#{@parent.full_name}::#{@name}"
                 else
                   @name
                 end
end
merge(class_module)

Merges class_module into this ClassModule.

The data in class_module is preferred over the receiver.

Source: show | on GitHub 

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

  if other_document then

    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

      @methods_hash.delete meth.pretty_name
    end
  end

  self
end
module?()

Source: show | on GitHub 

# File ../ruby/lib/rdoc/class_module.rb, line 417
def module?
  false
end
name=(new_name)

Allows overriding the initial name.

Used for modules and classes that are constant aliases.

Source: show | on GitHub 

# File ../ruby/lib/rdoc/class_module.rb, line 465
def name_for_path
  is_alias_for ? is_alias_for.full_name : full_name
end

Source: show | on GitHub 

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

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

Source: show | on GitHub 

# File ../ruby/lib/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()

Path to this class or module

Source: show | on GitHub 

# File ../ruby/lib/rdoc/class_module.rb, line 456
def path
  http_url RDoc::RDoc.current.generator.class_dir
end
remove_nodoc_children()

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.

Source: show | on GitHub 

# File ../ruby/lib/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()

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

Source: show | on GitHub 

# File ../ruby/lib/rdoc/class_module.rb, line 504
def superclass
  RDoc::TopLevel.find_class_named(@superclass) || @superclass
end
superclass=(superclass)

Set the superclass of this class to superclass

Source: show | on GitHub 

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

'module' or 'class'

Source: show | on GitHub 

# File ../ruby/lib/rdoc/class_module.rb, line 527
def type
  module? ? 'module' : 'class'
end
update_aliases()

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.

Source: show | on GitHub 

# File ../ruby/lib/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()

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

Source: show | on GitHub 

# File ../ruby/lib/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
