 def update_tenant( self, tenant, update_mask=None, retry=google.api_core.gapic_v1.method.DEFAULT, timeout=google.api_core.gapic_v1.method.DEFAULT, metadata=None, ):
 """ Updates specified tenant. Example: Args: tenant (Union[dict, ~google.cloud.talent_v4beta1.types.Tenant]):
 Required. The tenant resource to replace the current resource in the system. If a dict is provided, it must be of the same form as the protobuf message :class:`~google.cloud.talent_v4beta1.types.Tenant` update_mask (Union[dict, ~google.cloud.talent_v4beta1.types.FieldMask]):
 Optional but strongly recommended for the best service experience. If ``update_mask`` is provided, only the specified fields in ``tenant`` are updated. Otherwise all the fields are updated. A field mask to specify the tenant fields to be updated. Only top level fields of ``Tenant`` are supported. If a dict is provided, it must be of the same form as the protobuf message :class:`~google.cloud.talent_v4beta1.types.FieldMask` retry (Optional[google.api_core.retry.Retry]):
 A retry object used to retry requests. If ``None`` is specified, requests will not be retried. timeout (Optional[float]):
 The amount of time, in seconds, to wait for the request to complete. Note that if ``retry`` is specified, the timeout applies to each individual attempt. metadata (Optional[Sequence[Tuple[str, str]]]):
 Additional metadata that is provided to the method. Returns: A :class:`~google.cloud.talent_v4beta1.types.Tenant` instance. Raises: google.api_core.exceptions.GoogleAPICallError: If the request failed for any reason. google.api_core.exceptions.RetryError: If the request failed due to a retryable error and retry attempts failed. ValueError: If the parameters are invalid. """
