Instance Method Details
#add_comment(comment, location) ⇒ Object
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.

#ancestors ⇒ Object Also known as: direct_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.

# File 'lib/rdoc/class_module.rb', line 180 def clear_comment @comment = '' end |
#comment=(comment) ⇒ Object
This method is deprecated, use #add_comment instead.
Appends comment
to the current comment, but separated by a rule. Works more like +=
.

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.

#update_aliases ⇒ Object
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::Store#modules_hash or RDoc::Store#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.
