Hmmm ... this seems like a perfect spot for forwardable.rb to me:

require "forwardable"

class Text
  extend Forwardable

  def initialize(component)
    if(component <= 1)
      @proxy = TextSingle.new
    else
      @proxy = TextMultiple.new
    end
  end

  def_delegator(:@proxy, :meth)

  class TextSingle
    def meth
      puts "I'm from TextSingle!"
    end
  end

  class TextMultiple
    def meth
      puts "I'm from TextMultiple!"
    end
  end
end
