### Method Details

`list(parent, pageToken=None, pageSize=None, messageTypes=None, x__xgafv=None)`

    Returns user facing log messages for the data transfer run.

    Args:
      parent: string, Required. Transfer run name in the form:
    `projects/{project_id}/transferConfigs/{config_id}/runs/{run_id}` or
    `projects/{project_id}/locations/{location_id}/transferConfigs/{config_id}/runs/{run_id}` (required)
      pageToken: string, Pagination token, which can be used to request a specific page
    of `ListTransferLogsRequest` list results. For multiple-page
    results, `ListTransferLogsResponse` outputs
    a `next_page` token, which can be used as the
    `page_token` value to request the next page of list results.
      pageSize: integer, Page size. The default page size is the maximum value of 1000 results.
      messageTypes: string, Message types to return. If not populated - INFO, WARNING and ERROR
    messages are returned. (repeated)
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

        { # The returned list transfer run messages.
        "transferMessages": [ # Output only. The stored pipeline transfer messages.
          { # Represents a user facing message for a particular data transfer run.
            "messageTime": "A String", # Time when message was logged.
            "severity": "A String", # Message severity.
            "messageText": "A String", # Message text.
          },
        ],
        "nextPageToken": "A String", # Output only. The next-pagination token. For multiple-page list results,
            # this token can be used as the
            # `GetTransferRunLogRequest.page_token`
            # to request the next page of list results.
      }

`list_next(previous_request, previous_response)`

    Retrieves the next page of results.

    Args:
      previous_request: The request for the previous page. (required)
      previous_response: The response from the request for the previous page. (required)
