public virtual QAMessage * getMessageBySelector(
     qa_const_string address,
    qa_const_string selector
)

The next QAMessage, or null if no message is available.

The address parameter specifies a local queue name. The address can be in the form 'store-id\queue-name' or 'queue-name'. If there is no message available, this call blocks indefinitely until a message is available. Use this method to receive messages synchronously.
