      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.

      Sets the HttpPipeline to use for the service 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.

    • clientOptions

      public DataLakeFileSystemClientBuilder clientOptions(com.azure.core.util.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.

      Specified by:
      clientOptions in interface com.azure.core.client.traits.HttpTrait<DataLakeFileSystemClientBuilder>
      Parameters:
      clientOptions - A configured instance of HttpClientOptions.
      Returns:
      the updated DataLakeFileSystemClientBuilder object
      Throws:
      NullPointerException - If clientOptions is null.
      See Also:
      • HttpClientOptions

    • serviceVersion

      public DataLakeFileSystemClientBuilder serviceVersion(DataLakeServiceVersion version)
      Sets the DataLakeServiceVersion 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 - DataLakeServiceVersion of the service to be used when making requests.
      Returns:
      the updated DataLakeFileSystemClientBuilder object
