Overview

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:

  • RDoc::Context
    • RDoc::TopLevel
    • RDoc::ClassModule
      • RDoc::NormalClass
      • RDoc::NormalModule
      • RDoc::SingleClass
  • RDoc::MethodAttr
    • RDoc::Attr
    • RDoc::AnyMethod
  • RDoc::Alias
  • RDoc::Constant
  • RDoc::Require
  • RDoc::Mixin
    • RDoc::Include
    • RDoc::Extend

Instance Method Details

#display? ⇒ Boolean

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

Returns:

  • (Boolean) 


160
161
162
163
 
# File 'lib/rdoc/code_object.rb', line 160

def display?
  @document_self and not @ignored and
    (documented? or not @suppressed)
end

#documented? ⇒ Boolean

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

Returns:

  • (Boolean) 


191
192
193
 
# File 'lib/rdoc/code_object.rb', line 191

def documented?
  @received_nodoc or !@comment.empty?
end

#file_name ⇒ Object

File name where this CodeObject was found.

218
219
220
 
# File 'lib/rdoc/code_object.rb', line 216

def file_name
  return unless @file

  @file.absolute_name
end

#full_name=(full_name) ⇒ Object

Sets the full_name overriding any computed full name.

Set to nil to clear RDoc's cached value



237
238
239
 
# File 'lib/rdoc/code_object.rb', line 237

def full_name=(full_name)
  @full_name = full_name
end

#ignore ⇒ Object

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.
