You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: mounter.rb
    path of file: ./repos/padrino-framework/padrino-core/lib/padrino-core
    
    the code of the file until where you have to start completion: require 'padrino-core/mounter/application_extension'

module Padrino
  ##
  # Represents a particular mounted Padrino application.
  # Stores the name of the application (app folder name) and url mount path.
  #
  # @example
  #   Mounter.new("blog_app", :app_class => "Blog").to("/blog")
  #   Mounter.new("blog_app", :app_file => "/path/to/blog/app.rb").to("/blog")
  #
  class Mounter
    DEFAULT_CASCADE = 
    
    def initialize(name, options={})
      @name      = name.to_s
      @app_class = options[:app_class] || Inflections.camelize(@name)
      @gem       = options[:gem]       || Inflections.underscore(@app_class.split("::").first)
      @app_file  = options[:app_file]  || locate_app_file
      @app_obj   = options[:app_obj]   || app_constant || locate_app_object
      ensure_app_file! || ensure_app_object!
      unless padrino_application?
        @app_obj.extend ApplicationExtension
        @app_obj.mounter_options = options
