#raise_on_error(response_xml) ⇒ Object

Raises an exception if the response is an error. Since in some response types the error code is not named “errorCode” it is not possible to call this method only in the constructur of this base class. This is sufficient for services using the BaseResponse directly but subclasses of BaseResponse need to call this method at the end of their constructure initialize.

def raise_on_error(response_xml)
  if @error_code && !@error_code.empty? &&  @error_code != "0000" then

    # It is important to create the exception with self.class.new and not only BasicResponse.new
    # This is because this method can be also invoked from a subclass. If a VoiceCallResponse object for example
    # raises an exception you will receive "VoiceCallResponse" from self.class. This is very important because
    # only the VoiceCallResponse knows that in this case the response code is called <tt>status</tt>.
    # This is because there is an inconsistency within the different service responses. 
    raise(ServiceException.new( self.class.new(response_xml, false) ), "The developer garden service you invoked responded with an error: " + @error_message.to_s)
  end
end

#to_s ⇒ Object

Returns self.inspect. Good for debugging purposes.
