 def batch_get_assets_history( self, parent, content_type, read_time_window, asset_names=None, retry=google.api_core.gapic_v1.method.DEFAULT, timeout=google.api_core.gapic_v1.method.DEFAULT, metadata=None, ):
 """ Batch gets the update history of assets that overlap a time window. For RESOURCE content, this API outputs history with asset in both non-delete or deleted status. For IAM\_POLICY content, this API outputs history when the asset and its attached IAM POLICY both exist. This can create gaps in the output history. If a specified asset does not exist, this API returns an INVALID\_ARGUMENT error. Example: Args: parent (str):
 Required. The relative name of the root asset. It can only be an organization number (such as "organizations/123"), a project ID (such as "projects/my-project-id")", or a project number (such as "projects/12345"). content_type (~google.cloud.asset_v1.types.ContentType):
 Required. The content type. read_time_window (Union[dict, ~google.cloud.asset_v1.types.TimeWindow]):
 Optional. The time window for the asset history. Both start\_time and end\_time are optional and if set, it must be after 2018-10-02 UTC. If end\_time is not set, it is default to current timestamp. If start\_time is not set, the snapshot of the assets at end\_time will be returned. The returned results contain all temporal assets whose time window overlap with read\_time\_window. If a dict is provided, it must be of the same form as the protobuf message :class:`~google.cloud.asset_v1.types.TimeWindow` asset_names (list[str]):
 A list of the full names of the assets. For example: ``//compute.googleapis.com/projects/my_project_123/zones/zone1/instances/instance1``. See `Resource Names <https://cloud.google.com/apis/design/resource_names#full_resource_name>`__ and `Resource Name Format <https://cloud.google.com/resource-manager/docs/cloud-asset-inventory/resource-name-format>`__ for more info. The request becomes a no-op if the asset name list is empty, and the max size of the asset name list is 100 in one request. 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.asset_v1.types.BatchGetAssetsHistoryResponse` 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. """
