Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Holds all the references of all the registered subclasses of a view. We have one registry for each superclass view.

Examples:

require 'lotus/view'

module Articles
  class Index
    include Lotus::View
  end

  class Show
    include Lotus::View
  end

  class JsonShow < Show
    format :json
  end

  class XmlShow < Show
    format :xml

    def render
      ArticleSerializer.new(article).to_xml
    end
  end
end

# We have the following templates:
#
#  * articles/index.html.erb
#  * articles/index.atom.erb
#  * articles/show.html.erb
#  * articles/show.json.erb

# One registry per superclass view
Articles::Index.send(:registry).object_id     # => 70135342862240

Articles::Show.send(:registry).object_id      # => 70135342110540
Articles::XmlShow.send(:registry).object_id   # => 70135342110540
Articles::JsonShow.send(:registry).object_id  # => 70135342110540

# It holds the references for all the templates and the views
Articles::Index.send(:registry).inspect
  # => { :all  => [Articles::Index, nil],
  #      :atom => [Articles::Index, #<Lotus::View::Template ... @file="/path/to/templates/articles/index.atom.erb"],
  #      :html => [Articles::Index, #<Lotus::View::Template ... @file="/path/to/templates/articles/index.html.erb"] }

Articles::Show.send(:registry).inspect
  # => { :all  => [Articles::Show, nil],
  #      :html => [Articles::Show,     #<Lotus::View::Template ... @file="/path/to/templates/articles/show.html.erb"],
  #      :json => [Articles::JsonShow, #<Lotus::View::Template ... @file="/path/to/templates/articles/show.json.erb"],
  #      :xml  => [Articles::XmlShow, nil] }
