/**
* Interface for accessing AmazonSQS.
* Amazon Simple Queue Service
* Welcome to the Amazon Simple Queue Service API Reference . This
* section describes who should read this guide, how the guide is
* organized, and other resources related to the Amazon Simple Queue
* Service (Amazon SQS).
*
*
* Amazon SQS offers reliable and scalable hosted queues for storing
* messages as they travel between computers. By using Amazon SQS, you
* can move data between distributed components of your applications that
* perform different tasks without losing messages or requiring each
* component to be always available.
*
*
* Helpful Links:
*
* -
* Current WSDL (2012-11-05)

* -
* Making API Requests
*

* Amazon SQS product page
*
* -
* Using Amazon SQS Dead Letter Queues
*
* -
* Regions and Endpoints
*
*
*
*
*
*
* We also provide SDKs that enable you to access Amazon SQS from your
* preferred programming language. The SDKs contain functionality that
* automatically takes care of tasks such as:
*
*
*
*
* - Cryptographically signing your service requests
* - Retrying requests
* - Handling error responses
*
*
*
*
*
* For a list of available SDKs, go to
* Tools for Amazon Web Services

* an existing queue to more than a total visibility timeout of 12 hours.
* (For more information visibility timeout, see
* Visibility Timeout
* in the Amazon SQS Developer Guide .)
*
*
* For example, let's say you have a message and its default message
* visibility timeout is 30 minutes. You could call
* ChangeMessageVisiblity with a value of two hours and the
* effective timeout would be two hours and 30 minutes. When that time
* comes near you could again extend the time out by calling

* NOTE: There is a 120,000 limit for the number of inflight
* messages per queue. Messages are inflight after they have been
* received from the queue by a consuming component, but have not yet
* been deleted from the queue. If you reach the 120,000 limit, you will

*
* IMPORTANT:If you attempt to set the VisibilityTimeout to an

*
* IMPORTANT:Unlike with a queue, when you change the visibility

/**
*
* Adds a permission to a queue for a specific
* principal
* . This allows for sharing access to the queue.
*
*
* When you create a queue, you have full control access rights for the
* queue. Only you (as owner of the queue) can grant or deny permissions
* to the queue. For more information about these permissions, see
* Shared Queues
* in the Amazon SQS Developer Guide .
*
*
* NOTE: AddPermission writes an Amazon SQS-generated policy. If
* you want to write your own policy, use SetQueueAttributes to upload
* your policy. For more information about writing your own policy, see
* Using The Access Policy Language in the Amazon SQS Developer Guide.
*
*
* 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
*
*
* @param queueUrl The URL of the Amazon SQS queue to take action on.
* @param label The unique identification of the permission you're
* setting (e.g., AliceSendMessage). Constraints: Maximum 80
* characters; alphanumeric characters, hyphens (-), and underscores (_)
* are allowed.
* @param aWSAccountIds The AWS account number of the principal
* who will be given permission. The principal must have an AWS account,
* but does not need to be signed up for Amazon SQS. For information
* about locating the AWS account identification, see Your
* AWS Identifiers in the Amazon SQS Developer Guide.
* @param actions The action the client wants to allow for the specified
* principal. The following are valid values: * | SendMessage |
* ReceiveMessage | DeleteMessage | ChangeMessageVisibility |
* GetQueueAttributes | GetQueueUrl. For more information about
* these actions, see Understanding
* Permissions in the Amazon SQS Developer Guide.
* Specifying SendMessage, DeleteMessage, or
* ChangeMessageVisibility for the ActionName.n
* also grants permissions for the corresponding batch versions of those
* actions: SendMessageBatch,
* DeleteMessageBatch, and
* ChangeMessageVisibilityBatch.
*
* @return The response from the AddPermission service method, as
* returned by AmazonSQS.
*

*
* @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.

* Deletes the specified message from the specified queue. You specify
* the message by using the message's receipt handle and not
* the message ID you received when you sent the message.
* Even if the message is locked by another reader due to the visibility
* timeout setting, it is still deleted from the queue. If you leave a
* message in the queue for longer than the queue's configured retention
* period, Amazon SQS automatically deletes it.
*
*
* NOTE: The receipt handle is associated with a specific
* instance of receiving the message. If you receive a message more than
* once, the receipt handle you get each time you receive the message is
* different. When you request DeleteMessage, if you don't provide the
* most recently received receipt handle for the message, the request
* will still succeed, but the message might not be deleted.
*
*
* IMPORTANT: It is possible you will receive a message even
* after you have deleted it. This might happen on rare occasions if one
* of the servers storing a copy of the message is unavailable when you
* request to delete the message. The copy remains on the server and
* might be returned to you again on a subsequent receive request. You
* should create your system to be idempotent so that receiving a
* particular message more than once is not a problem.
