public final class QueueClientBuilder
implements TokenCredentialTrait<QueueClientBuilder>, ConnectionStringTrait<QueueClientBuilder>, AzureNamedKeyCredentialTrait<QueueClientBuilder>, AzureSasCredentialTrait<QueueClientBuilder>, HttpTrait<QueueClientBuilder>, ConfigurationTrait<QueueClientBuilder>, EndpointTrait<QueueClientBuilder>

This class provides a fluent builder API to help aid the configuration and instantiation of the QueueClient and QueueAsyncClient, calling buildClient() constructs an instance of QueueClient and calling buildAsyncClient() constructs an instance of QueueAsyncClient.

The client needs the endpoint of the Azure Storage Queue service, name of the queue, and authorization credentials. endpoint(String endpoint) gives the builder the endpoint and may give the builder the queueName(String queueName) and a sasToken(String sasToken) that authorizes the client.

Instantiating a synchronous Queue Client with SAS token

QueueClient client = new QueueClientBuilder()
     .endpoint("https://${accountName}.queue.core.windows.net?${SASToken}")
     .buildClient();

Instantiating an Asynchronous Queue Client with SAS token

QueueAsyncClient queueAsyncClient = new QueueClientBuilder()
     .endpoint("https://{accountName}.queue.core.windows.net?{SASToken}")
     .buildAsyncClient();

If the endpoint doesn't contain the queue name or SAS token they may be set using queueName(String queueName) and sasToken(String sasToken).

Instantiating a synchronous Queue Client with credential

QueueClient client = new QueueClientBuilder()
     .endpoint("https://${accountName}.queue.core.windows.net")
     .queueName("myqueue")
     .sasToken("{SASTokenQueryParams}")
     .buildClient();

Instantiating an Asynchronous Queue Client with credential

QueueAsyncClient queueAsyncClient = new QueueClientBuilder()
     .endpoint("https://{accountName}.queue.core.windows.net")
     .queueName("myqueue")
     .sasToken("{SASTokenQueryParams}")
     .buildAsyncClient();

Another way to authenticate the client is using a StorageSharedKeyCredential. To create a StorageSharedKeyCredential a connection string from the Storage Queue service must be used. Set the StorageSharedKeyCredential with connectionString(String connectionString). If the builder has both a SAS token and StorageSharedKeyCredential the StorageSharedKeyCredential will be preferred when authorizing requests sent to the service.

Instantiating a synchronous Queue Client with connection string.

String connectionString = "DefaultEndpointsProtocol=https;AccountName={name};"
     + "AccountKey={key};EndpointSuffix={core.windows.net}";
 QueueClient client = new QueueClientBuilder()
     .connectionString(connectionString)
     .buildClient();

Instantiating an Asynchronous Queue Client with connection string.

String connectionString = "DefaultEndpointsProtocol=https;AccountName={name};"
     + "AccountKey={key};EndpointSuffix={core.windows.net}";
 QueueAsyncClient queueAsyncClient = new QueueClientBuilder()
     .connectionString(connectionString)
     .buildAsyncClient();

Constructor Details

QueueClientBuilder

public QueueClientBuilder()

Creates a builder instance that is able to configure and construct QueueClient and QueueAsyncClient.

Method Details

addPolicy

public QueueClientBuilder addPolicy(HttpPipelinePolicy pipelinePolicy)

Adds a HttpPipelinePolicy to apply on each request sent.

Note: It is important to understand the precedence order of the HttpTrait APIs. In particular, if a HttpPipeline is specified, this takes precedence over all other APIs in the trait, and they will be ignored. If no HttpPipeline is specified, a HTTP pipeline will be constructed internally based on the settings provided to this trait. Additionally, there may be other APIs in types that implement this trait that are also ignored if an HttpPipeline is specified, so please be sure to refer to the documentation of types that implement this trait to understand the full set of implications.

Parameters:

pipelinePolicy - A HttpPipelinePolicy.

Returns:

the updated QueueClientBuilder object

audience

public QueueClientBuilder audience(QueueAudience audience)

Sets the Audience to use for authentication with Azure Active Directory (AAD). The audience is not considered when using a shared key.

Parameters:

audience - QueueAudience to be used when requesting a token from Azure Active Directory (AAD).

Returns:

the updated QueueClientBuilder object

buildAsyncClient

public QueueAsyncClient buildAsyncClient()

Creates a QueueAsyncClient based on options set in the builder. Every time buildAsyncClient() is called a new instance of QueueAsyncClient is created.

If pipeline(HttpPipeline httpPipeline) is set, then the pipeline, endpoint(String endpoint), and queueName(String queueName) are used to create the QueueAsyncClient. All other builder settings are ignored.

Returns:

A QueueAsyncClient with the options set from the builder.

buildClient

public QueueClient buildClient()

Creates a QueueClient based on options set in the builder. Every time buildClient() is called a new instance of QueueClient is created.

If pipeline(HttpPipeline httpPipeline) is set, then the pipeline, endpoint(String endpoint), and queueName(String queueName) are used to create the QueueAsyncClient. All other builder settings are ignored.

Returns:

A QueueClient with the options set from the builder.

clientOptions

public QueueClientBuilder clientOptions(ClientOptions clientOptions)

Allows for setting common properties such as application ID, headers, proxy configuration, etc. Note that it is recommended that this method be called with an instance of the HttpClientOptions class (a subclass of the ClientOptions base class). The HttpClientOptions subclass provides more configuration options suitable for HTTP clients, which is applicable for any class that implements this HttpTrait interface.

Note: It is important to understand the precedence order of the HttpTrait APIs. In particular, if a HttpPipeline is specified, this takes precedence over all other APIs in the trait, and they will be ignored. If no HttpPipeline is specified, a HTTP pipeline will be constructed internally based on the settings provided to this trait. Additionally, there may be other APIs in types that implement this trait that are also ignored if an HttpPipeline is specified, so please be sure to refer to the documentation of types that implement this trait to understand the full set of implications.

processMessageDecodingError

public QueueClientBuilder processMessageDecodingError(Consumer processMessageDecodingErrorHandler)

Sets the handler that performs the tasks needed when a message is received or peaked from the queue but cannot be decoded.

Such message can be received or peaked when queue is expecting certain QueueMessageEncoding but there's another producer that is not encoding messages in expected way. I.e. the queue contains messages with different encoding.

QueueMessageDecodingError contains QueueAsyncClient for the queue that has received the message as well as getQueueMessageItem() or getPeekedMessageItem() with raw body, i.e. no decoding will be attempted so that body can be inspected as has been received from the queue.

The handler won't attempt to remove the message from the queue. Therefore, such handling should be included into handler itself.

Code Samples

String connectionString = "DefaultEndpointsProtocol=https;AccountName={name};"
     + "AccountKey={key};EndpointSuffix={core.windows.net}";

 Consumer<QueueMessageDecodingError> processMessageDecodingErrorHandler =
     (queueMessageDecodingFailure) -> {
         QueueMessageItem queueMessageItem = queueMessageDecodingFailure.getQueueMessageItem();
         PeekedMessageItem peekedMessageItem = queueMessageDecodingFailure.getPeekedMessageItem();
         if (queueMessageItem != null) {
             System.out.printf("Received badly encoded message, messageId=%s, messageBody=%s",
                 queueMessageItem.getMessageId(),
                 queueMessageItem.getBody().toString());
             queueMessageDecodingFailure
                 .getQueueClient()
                 .deleteMessage(queueMessageItem.getMessageId(), queueMessageItem.getPopReceipt());
         } else if (peekedMessageItem != null) {
             System.out.printf("Peeked badly encoded message, messageId=%s, messageBody=%s",
                 peekedMessageItem.getMessageId(),
                 peekedMessageItem.getBody().toString());
         }
     };

 QueueClient client = new QueueClientBuilder()
     .connectionString(connectionString)
     .processMessageDecodingError(processMessageDecodingErrorHandler)
     .buildClient();

Parameters:

processMessageDecodingErrorHandler - the handler.

Returns:

the updated QueueClientBuilder object

processMessageDecodingErrorAsync

public QueueClientBuilder processMessageDecodingErrorAsync(Function<>> processMessageDecodingErrorAsyncHandler)

Sets the asynchronous handler that performs the tasks needed when a message is received or peaked from the queue but cannot be decoded.

Such message can be received or peaked when queue is expecting certain QueueMessageEncoding but there's another producer that is not encoding messages in expected way. I.e. the queue contains messages with different encoding.

QueueMessageDecodingError contains QueueAsyncClient for the queue that has received the message as well as getQueueMessageItem() or getPeekedMessageItem() with raw body, i.e. no decoding will be attempted so that body can be inspected as has been received from the queue.

The handler won't attempt to remove the message from the queue. Therefore, such handling should be included into handler itself.

Code Samples

String connectionString = "DefaultEndpointsProtocol=https;AccountName={name};"
     + "AccountKey={key};EndpointSuffix={core.windows.net}";

 Function<QueueMessageDecodingError, Mono<Void>> processMessageDecodingErrorHandler =
     (queueMessageDecodingFailure) -> {
         QueueMessageItem queueMessageItem = queueMessageDecodingFailure.getQueueMessageItem();
         PeekedMessageItem peekedMessageItem = queueMessageDecodingFailure.getPeekedMessageItem();
         if (queueMessageItem != null) {
             System.out.printf("Received badly encoded message, messageId=%s, messageBody=%s",
                 queueMessageItem.getMessageId(),
                 queueMessageItem.getBody().toString());

         } else {
             return Mono.empty();
         }

public QueueClientBuilder queueName(String queueName)

Sets the name of the queue that the client will interact with.

Parameters:

queueName - Name of the queue

Returns:

the updated QueueClientBuilder object

retryOptions

public QueueClientBuilder retryOptions(RetryOptions retryOptions)

Sets the RetryOptions for all the requests made through the client.

Note: It is important to understand the precedence order of the HttpTrait APIs. In particular, if a HttpPipeline is specified, this takes precedence over all other APIs in the trait, and they will be ignored. If no HttpPipeline is specified, a HTTP pipeline will be constructed internally based on the settings provided to this trait. Additionally, there may be other APIs in types that implement this trait that are also ignored if an HttpPipeline is specified, so please be sure to refer to the documentation of types that implement this trait to understand the full set of implications.

Setting this is mutually exclusive with using retryOptions(RequestRetryOptions retryOptions). Consider using retryOptions(RequestRetryOptions retryOptions) to also set storage specific options.

Parameters:

retryOptions - The RetryOptions to use for all the requests made through the client.

Returns:

the updated QueueClientBuilder object

retryOptions

public QueueClientBuilder retryOptions(RequestRetryOptions retryOptions)

Sets the request retry options for all the requests made through the client. Setting this is mutually exclusive with using retryOptions(RetryOptions retryOptions).

Parameters:

retryOptions - RequestRetryOptions.

Returns:

the updated QueueClientBuilder object.

sasToken

public QueueClientBuilder sasToken(String sasToken)

Sets the SAS token used to authorize requests sent to the service.

Parameters:

sasToken - The SAS token to use for authenticating requests. This string should only be the query parameters (with or without a leading '?') and not a full url.

Returns:

the updated QueueClientBuilder

serviceVersion

public QueueClientBuilder serviceVersion(QueueServiceVersion version)

Sets the QueueServiceVersion that is used when making API requests.

If a service version is not provided, the service version that will be used will be the latest known service version based on the version of the client library being used. If no service version is specified, updating to a newer version of the client library will have the result of potentially moving to a newer service version.

Targeting a specific service version may also mean that the service will return an error for newer APIs.

Parameters:

version - QueueServiceVersion of the service to be used when making requests.

Returns:

the updated QueueClientBuilder object
