Subject: proxy class / little factory

maybe someone can help me. i am trying to make a class such that when it
is used it acts like one or another class based on an attribute. i wrote
this little factory version:

class Text
    
  def new(component)
    if component <= 1
      return TextSingle.new
    else
      return TextMultiple.new
    end
  end

  class TextSingle
    def initilaize
      ...        
    end
  end
      
  class TextMultiple
    def initilaize
      ...        
    end      
  end

end

this could work (i actually haven't run it) but the problem is that the
type of the object returned is not Text, but TextSingle or TextMultiple.
i need it to be Text. eg.

  atext = Text.new(1)
  p atext.class  # --> TextSingle

for it it needs to be:

  p atext.class  # --> Text

suggestions?
