"""
Returns user facing log messages for the data transfer run.
Example:
>>> from google.cloud import bigquery_datatransfer_v1
>>>
>>> client = bigquery_datatransfer_v1.DataTransferServiceClient()
>>>
>>> parent = client.location_run_path('[PROJECT]', '[LOCATION]', '[TRANSFER_CONFIG]', '[RUN]')
>>>
>>>
>>> # Iterate over all results
>>> for element in client.list_transfer_logs(parent):
... # process element
... pass
>>>
>>> # Or iterate over results one page at a time
>>> for page in client.list_transfer_logs(parent, options=CallOptions(page_token=INITIAL_PAGE)):
... for element in page:
... # process element
... pass
Args:
parent (str): Transfer run name in the form:
``projects/{project_id}/transferConfigs/{config_Id}/runs/{run_id}``.
page_size (int): The maximum number of resources contained in the
underlying API response. If page streaming is performed per-
resource, this parameter does not affect the return value. If page
streaming is performed per-page, this determines the maximum number
of resources in a page.
message_types (list[~google.cloud.bigquery_datatransfer_v1.types.MessageSeverity]): Message types to return. If not populated - INFO, WARNING and ERROR
messages are returned.
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.
Returns:
A :class:`~google.gax.PageIterator` instance. By default, this
is an iterable of :class:`~google.cloud.bigquery_datatransfer_v1.types.TransferMessage` instances.
This object can also be configured to iterate over the pages
of the response through the `options` parameter.
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.
