## Methods

### BatchControllerClient

    BatchControllerClient(
        *,
        credentials: typing.Optional[google.auth.credentials.Credentials] = None,
        transport: typing.Optional[
            typing.Union[
                str,
                google.cloud.dataproc_v1.services.batch_controller.transports.base.BatchControllerTransport,
                typing.Callable[
                    [...],
                    google.cloud.dataproc_v1.services.batch_controller.transports.base.BatchControllerTransport,
                ],
            ]
        ] = None,
        client_options: typing.Optional[
            typing.Union[google.api_core.client_options.ClientOptions, dict]
        ] = None,
        client_info: google.api_core.gapic_v1.client_info.ClientInfo = google.api_core.gapic_v1.client_info.ClientInfo
    )

Instantiates the batch controller client.

| **Parameters** ||
|---|---|
| **Name** | **Description** |
| `credentials` | `Optional[google.auth.credentials.Credentials]` The authorization credentials to attach to requests. These credentials identify the application to the service; if none are specified, the client will attempt to ascertain the credentials from the environment. |
| `transport` | `Optional[Union[str,BatchControllerTransport,Callable[..., BatchControllerTransport]]]` The transport to use, or a Callable that constructs and returns a new transport. If a Callable is given, it will be called with the same set of initialization arguments as used in the BatchControllerTransport constructor. If set to None, a transport is chosen automatically. |
| `client_options` | `Optional[Union[google.api_core.client_options.ClientOptions, dict]]` Custom options for the client. 1. The `api_endpoint` property can be used to override the default endpoint provided by the client when `transport` is not explicitly provided. Only if this property is not set and `transport` was not explicitly provided, the endpoint is determined by the GOOGLE_API_USE_MTLS_ENDPOINT environment variable, which have one of the following values: "always" (always use the default mTLS endpoint), "never" (always use the default regular endpoint) and "auto" (auto-switch to the default mTLS endpoint if client certificate is present; this is the default value). 2. If the GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is "true", then the `client_cert_source` property can be used to provide a client certificate for mTLS transport. If not provided, the default SSL client certificate will be used if present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is "false" or not set, no client certificate will be used. 3. The `universe_domain` property can be used to override the default "googleapis.com" universe. Note that the `api_endpoint` property still takes precedence; and `universe_domain` is currently not supported for mTLS. |
| `client_info` | `google.api_core.gapic_v1.client_info.ClientInfo` The client info used to send a user-agent string along with API requests. If `None`, then default info will be used. Generally, you only need to set this if you're developing your own client library. |

| **Exceptions** ||
|---|---|
| **Type** | **Description** |
| `google.auth.exceptions.MutualTLSChannelError` | If mutual TLS transport creation failed for any reason. |

### __exit__

    __exit__(type, value, traceback)

Releases underlying transport's resources.

> [!WARNING]
> **Warning:** ONLY use as a context manager if the transport is NOT shared with other clients! Exiting the with block will CLOSE the transport and may cause errors in other clients!

### batch_path

    batch_path(project: str, location: str, batch: str) -> str

Returns a fully-qualified batch string.

### cancel_operation

    cancel_operation(
        request: typing.Optional[
            typing.Union[google.longrunning.operations_pb2.CancelOperationRequest, dict]
        ] = None,
        *,
        retry: typing.Optional[
            typing.Union[
                google.api_core.retry.retry_unary.Retry,
                google.api_core.gapic_v1.method._MethodDefault,
            ]
        ] = _MethodDefault._DEFAULT_VALUE,
        timeout: typing.Union[float, object] = _MethodDefault._DEFAULT_VALUE,
        metadata: typing.Sequence[typing.Tuple[str, typing.Union[str, bytes]]] = ()
    ) -> None

Starts asynchronous cancellation on a long-running operation.

The server makes a best effort to cancel the operation, but success
is not guaranteed. If the server doesn't support this method, it returns
`google.rpc.Code.UNIMPLEMENTED`.

| **Parameters** ||
|---|---|
| **Name** | **Description** |
| `request` | `` `.operations_pb2.CancelOperationRequest` `` The request object. Request message for `CancelOperation` method. |
| `retry` | `google.api_core.retry.Retry` Designation of what errors, if any, should be retried. |
| `timeout` | `float` The timeout for this request. |
| `metadata` | `Sequence[Tuple[str, Union[str, bytes]]]` Key/value pairs which should be sent along with the request as metadata. Normally, each value must be of type `str`, but for metadata keys ending with the suffix `-bin`, the corresponding values must be of type `bytes`. |

| `` `.policy_pb2.Policy` `` | Defines an Identity and Access Management (IAM) policy. It is used to specify access control policies for Cloud Platform resources. A `Policy` is a collection of `bindings`. A `binding` binds one or more `members` to a single `role`. Members can be user accounts, service accounts, Google groups, and domains (such as G Suite). A `role` is a named list of permissions (defined by IAM or configured by users). A `binding` can optionally specify a `condition`, which is a logic expression that further constrains the role binding based on attributes about the request and/or target resource. \*\*JSON Example\*\* :: { "bindings": \[ { "role": "roles/resourcemanager.organizationAdmin", "members": \[ "user:mike@example.com", "group:admins@example.com", "domain:google.com", "serviceAccount:my-project-id@appspot.gserviceaccount.com" \] }, { "role": "roles/resourcemanager.organizationViewer", "members": \["user:eve@example.com"\], "condition": { "title": "expirable access", "description": "Does not grant access after Sep 2020", "expression": "request.time \< timestamp('2020-10-01t00:00:00.000z')",="" }="" }="" \]="" }="" \*\*yaml="" example\*\*="" ::="" bindings:="" -="" members:="" -="" user:mike@example.com="" -="" group:admins@example.com="" -="" domain:google.com="" -="" serviceaccount:my-project-id@appspot.gserviceaccount.com="" role:="" roles/resourcemanager.organizationadmin="" -="" members:="" -="" user:eve@example.com="" role:="" roles/resourcemanager.organizationviewer="" condition:="" title:="" expirable="" access="" description:="" does="" not="" grant="" access="" after="" sep="" 2020="" expression:="" request.time=""\>\< timestamp('2020-10-01t00:00:00.000z')="" for="" a="" description="" of="" iam="" and="" its="" features,="" see="" the=""\>`IAM developer's guide `__. |

### get_mtls_endpoint_and_cert_source

    get_mtls_endpoint_and_cert_source(
        client_options: typing.Optional[
            google.api_core.client_options.ClientOptions
        ] = None,
    )

Deprecated. Return the API endpoint and client cert source for mutual TLS.

The client cert source is determined in the following order:
(1) if `GOOGLE_API_USE_CLIENT_CERTIFICATE` environment variable is not "true", the
client cert source is None.
(2) if `client_options.client_cert_source` is provided, use the provided one; if the
default client cert source exists, use the default one; otherwise the client cert
source is None.

The API endpoint is determined in the following order:
(1) if `client_options.api_endpoint` if provided, use the provided one.
(2) if `GOOGLE_API_USE_CLIENT_CERTIFICATE` environment variable is "always", use the
default mTLS endpoint; if the environment variable is "never", use the default API
endpoint; otherwise if client cert source exists, use the default mTLS endpoint, otherwise
use the default API endpoint.

| **Parameter** ||
|---|---|
| **Name** | **Description** |
| `client_options` | `google.api_core.client_options.ClientOptions` Custom options for the client. Only the `api_endpoint` and `client_cert_source` properties may be used in this method. |

| **Exceptions** ||
|---|---|
| **Type** | **Description** |
| `google.auth.exceptions.MutualTLSChannelError` | If any errors happen. |

| **Returns** ||
|---|---|
| **Type** | **Description** |
