"""
Run asynchronous image detection and annotation for a list of generic
files, such as PDF files, which may contain multiple pages and multiple
images per page. Progress and results can be retrieved through the
``google.longrunning.Operations`` interface. ``Operation.metadata``
contains ``OperationMetadata`` (metadata). ``Operation.response``
contains ``AsyncBatchAnnotateFilesResponse`` (results).
Example:
>>> from google.cloud import vision_v1
>>>
>>> client = vision_v1.ImageAnnotatorClient()
>>>
>>> # TODO: Initialize `requests`:
>>> requests = []
>>>
>>> response = client.async_batch_annotate_files(requests)
>>>
>>> def callback(operation_future):
... # Handle result.
... result = operation_future.result()
>>>
>>> response.add_done_callback(callback)
>>>
>>> # Handle metadata.
>>> metadata = response.metadata()
Args:
requests (list[Union[dict, ~google.cloud.vision_v1.types.AsyncAnnotateFileRequest]]): Required. Individual async file annotation requests for this batch.
If a dict is provided, it must be of the same form as the protobuf
message :class:`~google.cloud.vision_v1.types.AsyncAnnotateFileRequest`
parent (str): Optional. Target project and location to make a call.
Format: ``projects/{project-id}/locations/{location-id}``.
If no parent is specified, a region will be chosen automatically.
Supported location-ids: ``us``: USA country only, ``asia``: East asia
areas, like Japan, Taiwan, ``eu``: The European Union.
Example: ``projects/project-A/locations/eu``.
retry (Optional[google.api_core.retry.Retry]): A retry object used
to retry requests. If ``None`` is specified, requests will
be retried using a default configuration.
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.vision_v1.types._OperationFuture` 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.
