Implements

public class DataLakeFileSystemClientBuilder
implements TokenCredentialTrait<DataLakeFileSystemClientBuilder>, AzureNamedKeyCredentialTrait<DataLakeFileSystemClientBuilder>, AzureSasCredentialTrait<DataLakeFileSystemClientBuilder>, HttpTrait<DataLakeFileSystemClientBuilder>, ConfigurationTrait<DataLakeFileSystemClientBuilder>, EndpointTrait<DataLakeFileSystemClientBuilder>

This class provides a fluent builder API to help aid the configuration and instantiation of DataLakeFileSystemClient and DataLakeFileSystemAsyncClient, call buildClient() and buildAsyncClient() respectively to construct an instance of the desired client.

The following information must be provided on this builder:

  • the endpoint through .endpoint(), including the file system name, in the format of https://{accountName}.dfs.core.windows.net/{fileSystemName}.
  • the credential through .credential() or .connectionString() if the file system is not publicly accessible.

Constructor Details

DataLakeFileSystemClientBuilder

public DataLakeFileSystemClientBuilder()

Creates a builder instance that is able to configure and construct DataLakeFileSystemClient and DataLakeFileSystemAsyncClient.

Method Details

addPolicy

public DataLakeFileSystemClientBuilder 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 DataLakeFileSystemClientBuilder object

audience

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

Returns:

the updated DataLakeFileSystemClientBuilder object

buildAsyncClient

public DataLakeFileSystemAsyncClient buildAsyncClient()

Code Samples

DataLakeFileSystemAsyncClient client = new DataLakeFileSystemClientBuilder()
     .endpoint(endpoint)
     .credential(storageSharedKeyCredential)
     .buildAsyncClient();

Returns:

a DataLakeFileSystemAsyncClient created from the configurations in this builder.

buildClient

public DataLakeFileSystemClient buildClient()

Code Samples

DataLakeFileSystemClient client = new DataLakeFileSystemClientBuilder()
     .endpoint(endpoint)
     .credential(storageSharedKeyCredential)
     .buildClient();

Returns:

a DataLakeFileSystemClient created from the configurations in this builder.

clientOptions

public DataLakeFileSystemClientBuilder 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.
