RDoc::CodeObject

Base class for the RDoc code tree.

We contain the common stuff for contexts (which are containers) and other elements (methods, attributes and so on)

Here's the tree of the CodeObject subclasses:

Attributes

comment[R]

Our comment

document_children[R]

Do we document our children?

document_self[R]

Do we document ourselves?

done_documenting[R]

Are we done documenting (ie, did we come across a :enddoc:)?

file[R]

Which file this code object was defined in

force_documentation[R]

Force documentation of this CodeObject

line[RW]

Line in file where this CodeObject was defined

metadata[R]

Hash of arbitrary metadata for this CodeObject

parent[W]

Sets the parent CodeObject

received_nodoc[R]

Did we ever receive a :nodoc: directive?

section[W]

Set the section this CodeObject is in

store[R]

The RDoc::Store for this object.

viewer[RW]

We are the model of the code, but we know that at some point we will be worked on by viewers. By implementing the Viewable protocol, viewers can associated themselves with these objects.

Public Class Methods

new() click to toggle source

Creates a new CodeObject that will document itself and its children

  @metadata         = {}
  @comment          = ''

Public Instance Methods

comment=(comment) click to toggle source

Replaces our comment with comment, unless it is empty.

 
               # File rdoc/code_object.rb, line 134
def comment=(comment)
  @comment = case comment
             when NilClass               then ''
             when RDoc::Markup::Document then comment
             when RDoc::Comment          then comment.normalize
             else
               if comment and not comment.empty? then
                 normalize_comment comment
               else
                 # HACK correct fix is to have #initialize create @comment
                 #      with the correct encoding
                 if String === @comment and @comment.empty? then
                   @comment = RDoc::Encoding.change_encoding @comment, comment.encoding
                 end
                 @comment
               end
             end
end
display?() click to toggle source

Should this CodeObject be displayed in output?

A code object should be displayed if:

  • The item didn't have a nodoc or wasn't in a container that had nodoc

  • The item wasn't ignored

  • The item has documentation and was not suppressed

 
               # File rdoc/code_object.rb, line 162
def display?
  @document_self and not @ignored and
    (documented? or not @suppressed)
end
document_children=(document_children) click to toggle source

Enables or disables documentation of this CodeObject's children unless it has been turned off by :enddoc:

 
               # File rdoc/code_object.rb, line 171
def document_children=(document_children)
  return unless @track_visibility

  @document_children = document_children unless @done_documenting
end
document_self=(document_self) click to toggle source

Enables or disables documentation of this CodeObject unless it has been turned off by :enddoc:. If the argument is nil it means the documentation is turned off by :nodoc:.

 
               # File rdoc/code_object.rb, line 182
def document_self=(document_self)
  return unless @track_visibility
  return if @done_documenting

  @document_self = document_self
  @received_nodoc = true if document_self.nil?
end
documented?() click to toggle source

Does this object have a comment with content or is received_nodoc true?

 
               # File rdoc/code_object.rb, line 193
def documented?
  @received_nodoc or !@comment.empty?
end
done_documenting=(value) click to toggle source

Turns documentation on/off, and turns on/off document_self and document_children.

Once documentation has been turned off (by :enddoc:), the object will refuse to turn document_self or document_children on, so :doc: and :start_doc: directives will have no effect in the current file.

 
               # File rdoc/code_object.rb, line 206
def done_documenting=(value)
  return unless @track_visibility
  @done_documenting  = value
  @document_self     = !value
  @document_children = @document_self
end
each_parent() click to toggle source

Yields each parent of this CodeObject. See also RDoc::ClassModule#each_ancestor

 
               # File rdoc/code_object.rb, line 217
def each_parent
  code_object = self

  while code_object = code_object.parent do
    yield code_object
  end

  self
end
file_name() click to toggle source

File name where this CodeObject was found.

See also RDoc::Context#in_files

 
               # File rdoc/code_object.rb, line 232
def file_name
  return unless @file

  @file.absolute_name
end
force_documentation=(value) click to toggle source

Force the documentation of this object unless documentation has been turned off by :enddoc:

 
               # File rdoc/code_object.rb, line 244
def force_documentation=(value)
  @force_documentation = value unless @done_documenting
end
full_name=(full_name) click to toggle source

Sets the full_name overriding any computed full name.

Set to nil to clear RDoc's cached value

 
               # File rdoc/code_object.rb, line 253
def full_name= full_name
  @full_name = full_name
end
ignore() click to toggle source

Use this to ignore a CodeObject and all its children until found again (#record_location is called). An ignored item will not be displayed in documentation.

See github issue #55

The ignored status is temporary in order to allow implementation details to be hidden. At the end of processing a file RDoc allows all classes and modules to add new documentation to previously created classes.

If a class was ignored (via stopdoc) then reopened later with additional documentation it should be displayed. If a class was ignored and never reopened it should not be displayed. The ignore flag allows this to occur.

 
               # File rdoc/code_object.rb, line 273
def ignore
  return unless @track_visibility

  @ignored = true

  stop_doc
end
ignored?() click to toggle source

Has this class been ignored?

See also ignore

 
               # File rdoc/code_object.rb, line 286
def ignored?
  @ignored
end
options() click to toggle source

The options instance from the store this CodeObject is attached to, or a default options instance if the CodeObject is not attached.

This is used by Text#snippet

 
               # File rdoc/code_object.rb, line 296
def options
  if @store and @store.rdoc then
    @store.rdoc.options
  else
    RDoc::Options.new
  end
end
parent() click to toggle source

Our parent CodeObject. The parent may be missing for classes loaded from legacy RI data stores.

 
               # File rdoc/code_object.rb, line 308
def parent
  return @parent if @parent
  return nil unless @parent_name

  if @parent_class == RDoc::TopLevel then
    @parent = @store.add_file @parent_name
  else
    @parent = @store.find_class_or_module @parent_name

    return @parent if @parent

    begin
      @parent = @store.load_class @parent_name
    rescue RDoc::Store::MissingFileError
      nil
    end
  end
end
parent_file_name() click to toggle source

File name of our parent

 
               # File rdoc/code_object.rb, line 330
def parent_file_name
  @parent ? @parent.base_name : '(unknown)'
end
parent_name() click to toggle source

Name of our parent

 
               # File rdoc/code_object.rb, line 337

def record_location top_level
  @ignored    = false
  @suppressed = false
  @file       = top_level
end
section() click to toggle source

The section this CodeObject is in. Sections allow grouping of constants, attributes and methods inside a class or module.

 
               # File rdoc/code_object.rb, line 354
def section
  return @section if @section

  @section = parent.add_section @section_title if parent
end
start_doc() click to toggle source

Enable capture of documentation unless documentation has been turned off by :enddoc:

 
               # File rdoc/code_object.rb, line 364
def start_doc
  return if @done_documenting

  @document_self = true
  @document_children = true
  @ignored    = false
  @suppressed = false
end
stop_doc() click to toggle source

  if :nodoc == options.visibility then
    initialize_visibility
    @track_visibility = false
  end
end
suppress() click to toggle source

Use this to suppress a CodeObject and all its children until the next file it is seen in or documentation is discovered. A suppressed item with documentation will be displayed while an ignored item with documentation may not be displayed.

 
               # File rdoc/code_object.rb, line 403
def suppress
  return unless @track_visibility

  @suppressed = true

  stop_doc
end
