Subject: Type of class

Hi
How do I know if a variable is an instace of a given class

I have a method that returns a String or an Array and I have to know
outside if the returned object is and String or an Array.

Is beacuse this :
     # File vendor/rails/activerecord/lib/active_record/validations.rb,
line 100
100:     def on(attribute)
101:       errors = @errors[attribute.to_s]
102:       return nil if errors.nil?
103:       errors.size == 1 ? errors.first : errors
104:     end


How do I know that call on method on returned and array or an string?

Thanks
