/**
* Container for the parameters to the {@link com.amazonaws.services.sqs.AmazonSQS#createQueue(CreateQueueRequest) CreateQueue operation}.
*
* Creates a new queue, or returns the URL of an existing one. When you
* request CreateQueue , you provide a name for the queue.
* To successfully create a new queue, you must provide a name that is
* unique within the scope of your own queues.
*
*
* NOTE: If you delete a queue, you must wait at least 60 seconds
* before creating a queue with the same name.
*
*
* You may pass one or more attributes in the request. If you do not
* provide a value for any attribute, the queue will have the default
* value for that attribute. Permitted attributes are the same that can
* be set using SetQueueAttributes.
*
*
* NOTE: Use GetQueueUrl to get a queue's URL. GetQueueUrl
* requires only the QueueName parameter.
*
*
* If you provide the name of an existing queue, along with the exact
* names and values of all the queue's attributes,
* CreateQueue returns the queue URL for the existing queue.
* If the queue name, attribute names, or attribute values do not match
* an existing queue, CreateQueue returns an error.
*
*
* NOTE:Some API actions take lists of parameters. These lists are
* specified using the param.n notation. Values of n are integers
* starting from 1. For example, a parameter list with two elements looks
* like this:
*
*
* &Attribute.1=this
*
*
* &Attribute.2=that
*
*
* @see com.amazonaws.services.sqs.AmazonSQS#createQueue(CreateQueueRequest)
