Need to get the number of messages displayed

Question

Dear All,
I need to know whether the message area is having any messages or not. If messages are there then i need to get the exact number of the messages. I found the count in the class CL_WDR_MESSAGE_AREA. But the count is the private attribute. Is there any methods available to get the count of the number of mesages.
Thanks & Regards,
Raghuram K.R.
