/**

 * Retrieves one or more messages, with a maximum limit of 10 messages, from
 * the specified queue. Downloads the message payloads from Amazon S3 when
 * necessary. Long poll support is enabled by using the
 * <code>WaitTimeSeconds</code> parameter. For more information, see <a
 * href=
 * "http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-long-polling.html"
 * > Amazon SQS Long Poll </a> in the <i>Amazon SQS Developer Guide</i> .
 * </p>
 * <p>
 * Short poll is the default behavior where a weighted random set of
 * machines is sampled on a <code>ReceiveMessage</code> call. This means
 * only the messages on the sampled machines are returned. If the number of
 * messages in the queue is small (less than 1000), it is likely you will
 * get fewer messages than you requested per <code>ReceiveMessage</code>
 * call. If the number of messages in the queue is extremely small, you
 * might not receive any messages in a particular
 * <code>ReceiveMessage</code> response; in which case you should repeat the
 * request.
 * </p>
 * <p>
 * For each message returned, the response includes the following:
 * </p>
 * 
 * <ul>
 * <li>
 * <p>
 * Message body
 * </p>
 * </li>
 * <li>
 * <p>
 * MD5 digest of the message body. For information about MD5, go to <a
 * href="http://www.faqs.org/rfcs/rfc1321.html">
 * http://www.faqs.org/rfcs/rfc1321.html </a> .
 * </p>
 * </li>
 * <li>
 * <p>
 * Message ID you received when you sent the message to the queue.
 * </p>
 * </li>
 * <li>
 * <p>
 * Receipt handle.
 * </p>
 * </li>
 * <li>
 * <p>
 * Message attributes.
 * </p>
 * </li>
 * <li>
 * <p>
 * MD5 digest of the message attributes.
 * </p>
 * </li>
 * 
 * </ul>
 * <p>
 * The receipt handle is the identifier you must provide when deleting the
 * message. For more information, see <a href=
 * "http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/ImportantIdentifiers.html"
 * > Queue and Message Identifiers </a> in the <i>Amazon SQS Developer
 * Guide</i> .
 * </p>
 * <p>
 * You can provide the <code>VisibilityTimeout</code> parameter in your
 * request, which will be applied to the messages that Amazon SQS returns in
 * the response. If you do not include the parameter, the overall visibility
 * timeout for the queue is used for the returned messages. For more
 * information, see <a href=
 * "http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/AboutVT.html"
 * > Visibility Timeout </a> in the <i>Amazon SQS Developer Guide</i> .
 * </p>
 * <p>
 * <b>NOTE:</b> Going forward, new attributes might be added. If you are
 * writing code that calls this action, we recommend that you structure your
 * code so that it can handle new attributes gracefully.
 * </p>
 *
 * @param receiveMessageRequest
 *            Container for the necessary parameters to execute the
 *            ReceiveMessage service method on AmazonSQS.
 * 
 * @return The response from the ReceiveMessage service method, as returned
 *         by AmazonSQS.
 * 
 * @throws OverLimitException
 *
 * @throws AmazonClientException
 *             If any internal errors are encountered inside the client
 *             while attempting to make the request or handle the response.
 *             For example if a network connection is not available.
 * @throws AmazonServiceException
 *             If an error response is returned by AmazonSQS indicating
 *             either a problem with the data in the request, or a server
 *             side issue.
