/**
 * Service Description: Service that performs Google Cloud Vision API detection tasks over client
 * images, such as face, landmark, logo, label, and text detection. The
 * ImageAnnotator service returns detected entities from the images.
 *
 * This class provides the ability to make remote calls to the backing service through method
 * calls that map to API methods. Sample code to get started:
 *
 * ```
 * $imageAnnotatorClient = new ImageAnnotatorClient();
 * try {
 *     $requests = [];
 *     $operationResponse = $imageAnnotatorClient->asyncBatchAnnotateFiles($requests);
 *     $operationResponse->pollUntilComplete();
 *     if ($operationResponse->operationSucceeded()) {
 *         $result = $operationResponse->getResult();
 *     // doSomethingWith($result)
 *     } else {
 *         $error = $operationResponse->getError();
 *         // handleError($error)
 *     }
 *     // Alternatively:
 *     // start the operation, keep the operation name, and resume later
 *     $operationResponse = $imageAnnotatorClient->asyncBatchAnnotateFiles($requests);
 *     $operationName = $operationResponse->getName();
 *     // ... do other work
 *     $newOperationResponse = $imageAnnotatorClient->resumeOperation($operationName, 'asyncBatchAnnotateFiles');
 *     while (!$newOperationResponse->isDone()) {
 *         // ... do other work
 *         $newOperationResponse->reload();
 *     }
 *     if ($newOperationResponse->operationSucceeded()) {
 *         $result = $newOperationResponse->getResult();
 *     // doSomethingWith($result)
 *     } else {
 *         $error = $newOperationResponse->getError();
 *         // handleError($error)
 *     }
 * } finally {
 *     $imageAnnotatorClient->close();
