[docs] class DeleteData(utils.PayloadWrapper): r""" Convenience class for constructing a delete document, to use as the `data` parameter to :meth:`submit_delete <globus_sdk.TransferClient.submit_delete>`. At least one item must be added using :meth:`add_item <globus_sdk.DeleteData.add_item>`. If ``submission_id`` isn't passed, one will be fetched automatically. The submission ID can be pulled out of here to inspect, but the document can be used as-is multiple times over to retry a potential submission failure (so there shouldn't be any need to inspect it). :param transfer_client: A ``TransferClient`` instance which will be used to get a submission ID if one is not supplied. Should be the same instance that is used to submit the deletion. :param endpoint: The endpoint ID which is targeted by this deletion Task :param label: A string label for the Task :param submission_id: A submission ID value fetched via :meth:`get_submission_id <globus_sdk.TransferClient.get_submission_id>`. Defaults to using ``transfer_client.get_submission_id`` if a ``transfer_client`` is provided :param recursive: Recursively delete subdirectories on the target endpoint [default: ``False``] :param ignore_missing: Ignore nonexistent files and directories instead of treating them as errors. [default: ``False``] :param interpret_globs: Enable expansion of ``\*?[]`` characters in the last component of paths, unless they are escaped with a preceding backslash, ``\\`` [default: ``False``] :param deadline: An ISO-8601 timestamp (as a string) or a datetime object which defines a deadline for the deletion. At the deadline, even if the data deletion is not complete, the job will be canceled. We recommend ensuring that the timestamp is in UTC to avoid confusion and ambiguity. Examples of ISO-8601 timestamps include ``2017-10-12 09:30Z``, ``2017-10-12 12:33:54+00:00``, and ``2017-10-12`` :param skip_activation_check: When true, allow submission even if the endpoint isn't currently activated :param notify_on_succeeded: Send a notification email when the delete task completes with a status of SUCCEEDED. [default: ``True``] :param notify_on_failed: Send a notification email when the delete task completes with a status of FAILED. [default: ``True``] :param notify_on_inactive: Send a notification email when the delete task changes status to INACTIVE. e.g. From credentials expiring. [default: ``True``] :param local_user: Optional value passed to identity mapping specifying which local user account to map to. Only usable with Globus Connect Server v5 mapped collections. :param additional_fields: additional fields to be added to the delete document. Mostly intended for internal use **Examples** See the :meth:`submit_delete <globus_sdk.TransferClient.submit_delete>` documentation for example usage. **External Documentation** See the `Task document definition \ <>`_ and `Delete specific fields \ <>`_ in the REST documentation for more details on Delete Task documents. .. automethodlist:: globus_sdk.TransferData """ def __init__( self, transfer_client: globus_sdk.TransferClient | None = None, endpoint: UUIDLike | None = None, *, label: str | None = None, submission_id: UUIDLike | None = None, recursive: bool = False, ignore_missing: bool = False, interpret_globs: bool = False, deadline: str | datetime.datetime | None = None, skip_activation_check: bool | None = None, notify_on_succeeded: bool = True, notify_on_failed: bool = True, notify_on_inactive: bool = True, local_user: str | None = None, additional_fields: dict[str, t.Any] | None = None, ) -> None: super().__init__() # this must be checked explicitly to handle the fact that `transfer_client` is # the first arg if endpoint is None: raise exc.GlobusSDKUsageError("endpoint is required") self["DATA_TYPE"] = "delete" self["DATA"] = [] self._set_optstrs( endpoint=endpoint, label=label, submission_id=submission_id or ( transfer_client.get_submission_id()["value"] if transfer_client else None ), deadline=deadline, local_user=local_user, ) self._set_optbools( recursive=recursive, ignore_missing=ignore_missing, interpret_globs=interpret_globs, skip_activation_check=skip_activation_check, notify_on_succeeded=notify_on_succeeded, notify_on_failed=notify_on_failed, notify_on_inactive=notify_on_inactive, ) for k, v in self.items():"DeleteData.%s = %s", k, v) if additional_fields is not None: self.update(additional_fields) for option, value in additional_fields.items(): f"DeleteData.{option} = {value} (option passed " "in via additional_fields)" )
