General information

This method fails if the container does not contain any messages or receipt handles.

Example

Copy code
public void changeVisibility() {

        LrSqsClient.initClient(region, standardQueueUrl); 
            
        LrSqsClient.initMessageBatch();
        LrSqsClient.addMessageToBatch("m1");
        LrSqsClient.addMessageToBatch("m2");
        LrSqsClient.addMessageToBatch("m3");
        LrSqsClient.addMessageToBatch("m4");
        LrSqsClient.sendMessageBatch();
                
        LrSqsMessage message1 = LrSqsClient.receiveMessage();
        if (message1 != null){
            LrSqsClient.changeMessageVisibility(message1.receiptHandle(), 20);
        }
        List <LrSqsMessage> receivedMessages = LrSqsClient.receiveMessages(3, 20);
                
        LrSqsClient.initChangeMessageVisibilityBatch();
        int visibilityTimeout = 10;
        for (LrSqsMessage m : receivedMessages) {
            //LrSqsClient.addMessageToChangeVisibilityBatch(m, visibilityTimeout);
            LrSqsClient.addReceiptHandleToChangeVisibilityBatch(m.receiptHandle(), visibilityTimeout);
            visibilityTimeout += 2;
        }
        LrSqsClient.changeMessageVisibilityBatch();    
            
        LrSqsClient.closeClient();
