        Lists supported data sources and returns their settings,
        which can be used for UI rendering.

        Example:
            >>> from google.cloud import bigquery_datatransfer_v1
            >>>
            >>> client = bigquery_datatransfer_v1.DataTransferServiceClient()

            ...     # process element

            ...         # process element
            ...         pass

        Args:
            parent (str): The BigQuery project id for which data sources should be returned.
                Must be in the form: ``projects/{project_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.
            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.DataSource` 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.
