Sometimes it is necessary to retrieve the concrete adapter for the service that the
Queue API is working with. This can be achieved by using the
getAdapter() method.
Note
Accessing the underlying adapter breaks portability among services, so it should be reserved for exceptional circumstances only.
Example 94. Using a concrete adapter
<?php
// send the message directly with the SQS client library
$sqs = $queues->getAdapter();
$sqs->sendMessage("myQueue", "hello!");
