### Method Details

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

      messageTypes: string, Message types to return. If not populated - INFO, WARNING and ERROR
    messages are returned. (repeated)
      pageToken: string, Pagination token, which can be used to request a specific page
    of `ListTransferLogsRequest` list results. For multiple-page

      An object of the form:

        { # The returned list transfer run messages.
        "nextPageToken": "A String", # 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.
            # @OutputOnly
