and method or attribute name name
.
Usually this is called by super from a subclass.

# File lib/rdoc/code_object/method_attr.rb, line 209 def add_alias(an_alias, context) raise NotImplementedError end
Abstract method. Contexts in their building phase call this to register a new alias for this known method/attribute.
-
creates a new AnyMethod/Attribute named
an_alias.new_name
; -
adds
self
as an alias for the new method or attribute -
adds the method or attribute to

-
adds the method or attribute to

Prepend src
with line numbers. Relies on the first line of a source code listing having:
# File xxxxx, line dddd
If it has this comment then line numbers are added to src
and the , line dddd
portion of the comment is removed.

A method/attribute is documented if any of the following is true:
-
it was marked with :nodoc:;
-
it has a comment;
-
it is an alias for a documented method;
-
it has a
#see
method that is documented.

Prepends line numbers if options.line_numbers
is true.

# File lib/rdoc/code_object/method_attr.rb, line 319 def name_prefix @singleton ? '::' : '#' end
‘::’ for a class method/attribute, ‘#’ for an instance method.
Source
# File lib/rdoc/code_object/method_attr.rb, line 330 def output_name context return "#{name_prefix}#{@name}" if context == parent "#{parent_name}#{@singleton ? '.' : '#'}#{@name}" end
Name for output to HTML. For class methods the full name with a “.” is used like SomeClass.method_name
. For instance methods the class name is used if context
does not match the parent.
- This is to help prevent people from using
-
to call class methods.

# File lib/rdoc/code_object/method_attr.rb, line 152 def see @see = find_see if @see == false @see end
A method/attribute to look at, in particular if this method/attribute has no documentation.
It can be a method/attribute of the superclass or of an included module, including the Kernel module, which is always appended to the included modules.
Returns nil
if there is no such method/attribute. The #is_alias_for
method/attribute, if any, is not included.
Templates may generate a “see also …” if this method/attribute has documentation, and “see …” if it does not.
