/**
* Container for the parameters to the {@link com.amazonaws.services.sqs.AmazonSQS#receiveMessage(ReceiveMessageRequest) ReceiveMessage operation}.
*
* Retrieves one or more messages, with a maximum limit of 10 messages,
* from the specified queue. Long poll support is enabled by using the
* WaitTimeSeconds parameter. For more information, see
* Amazon SQS Long Poll
* in the Amazon SQS Developer Guide .
*
*
*
* Short poll is the default behavior where a weighted random set of
* machines is sampled on a ReceiveMessage 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
* ReceiveMessage call. If the number of messages in the
* queue is extremely small, you might not receive any messages in a
* particular ReceiveMessage response; in which case you
* should repeat the request.
*
*
* For each message returned, the response includes the following:
*
*
*
* -
* Message body
*
*
* -
* MD5 digest of the message body. For information about MD5, go to
* http://www.faqs.org/rfcs/rfc1321.html
* .
*
*
* -
* Message ID you received when you sent the message to the queue.
*
*
* -
* Receipt handle.
*
*
* -
* Message attributes.
*
*
* -
* MD5 digest of the message attributes.
*
*
*
*
*
* The receipt handle is the identifier you must provide when deleting
* the message. For more information, see
* Queue and Message Identifiers
* in the Amazon SQS Developer Guide .
*
*
*
* You can provide the VisibilityTimeout 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
* Visibility Timeout
* in the Amazon SQS Developer Guide .
*
*
*
* NOTE: 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.
*
