Class CreateQueueRequest

java.lang.Object

com.amazonaws.AmazonWebServiceRequest

com.amazonaws.services.sqs.model.CreateQueueRequest

All Implemented Interfaces:

ReadLimitInfo, Serializable, Cloneable

public class CreateQueueRequest
extends AmazonWebServiceRequest
implements Serializable, Cloneable

Container for the parameters to the 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

Constructor Detail

CreateQueueRequest

public CreateQueueRequest()
