Sections are equal when they have the same title

def == other
  self.class === other and @title == other.title
end
add_comment(comment)

Adds comment to this section

# File lib/rdoc/context/section.rb, line 63
def add_comment comment
  comment = extract_comment comment

  return if comment.empty?

  case comment

    @comments.concat comment.parts

    raise TypeError, "unknown comment type: #{comment.inspect}"

aref()

Anchor reference for linking to this section

# File lib/rdoc/context/section.rb, line 83
def aref
  title = @title || '[untitled]'

  CGI.escape(title).gsub('%', '-').sub(/^-/, '')
end
extract_comment(comment)

Extracts the comment for this section from the original comment block. If the first line contains :section:, strip it and use the rest. Otherwise remove lines up to the line containing :section:, and look for those lines again at the end and remove them. This lets us write

# :section: The title
# The body

# File lib/rdoc/context/section.rb, line 98

in_files()

The files comments in this section come from

# File lib/rdoc/context/section.rb, line 133
def in_files
  return [] if @comments.empty?

  case @comments
  when Array then

      document.file
    end
  else
    raise RDoc::Error, "BUG: unknown comment class #{@comments.class}"
  end
end
marshal_dump()

Serializes this Section. The title and parsed comment are saved, but not the section parent which must be restored manually.

Source: show | on GitHub 

# File lib/rdoc/context/section.rb, line 154
def marshal_dump
  [
    MARSHAL_VERSION,
    @title,
    parse,
  ]
end
marshal_load(array)

De-serializes this Section. The section parent must be restored manually.

Source: show | on GitHub 

# File lib/rdoc/context/section.rb, line 165
def marshal_load array
  @parent  = nil

  @title    = array[1]
  @comments = array[2]
end
parse()

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

Source: show | on GitHub 

# File lib/rdoc/context/section.rb, line 176
def parse
  case @comments
  when String then
    super
  when Array then
    docs = @comments.map do |comment, location|
      doc = super comment
      doc.file = location if location
      doc
    end

    RDoc::Markup::Document.new(*docs)
  when RDoc::Comment then
    doc = super @comments.text, comments.format
    doc.file = @comments.location
    doc
  when RDoc::Markup::Document then
    return @comments
  else
    raise ArgumentError, "unknown comment class #{comments.class}"
  end
end
plain_html()

The section's title, or 'Top Section' if the title is nil.

This is used by the table of contents template so the name is silly.

# File lib/rdoc/context/section.rb, line 204
def plain_html
  @title || 'Top Section'
end
remove_comment(comment)

Removes a comment from this section if it is from the same file as comment

  return if @comments.empty?

  case @comments
  when Array then
    @comments.delete_if do |my_comment|
      my_comment.file == comment.file
    end
  when RDoc::Markup::Document then
    @comments.parts.delete_if do |document|
      document.file == comment.file.name
    end
  else
    raise RDoc::Error, "BUG: unknown comment class #{@comments.class}"
  end
end
