pynetdicom._handlers.doc_handle_delete(event: Event, *args: Sequence[Any]) Union[int, Dataset][source]

Documentation for handlers bound to evt.EVT_N_DELETE.

User implementation of this event handler is required if one or more services that use N-DELETE are to be supported. If a handler is not implemented and bound to evt.EVT_N_DELETE then the N-DELETE request will be responded to using a Status value of 0x0110 - Processing failure.



Supported Service Classes


0x0000 - Success
0x0110 - Processing failure
0x0112 - No such SOP Instance
0x0117 - Invalid object Instance
0x0118 - Not such SOP Class
0x0119 - Class-Instance conflict
0x0124 - Not authorised
0x0210 - Duplicate invocation
0x0211 - Unrecognised operation
0x0212 - Mistyped argument

  • event (events.Event) –

    The event representing a service class receiving a N-DELETE request message. Event attributes are:

    Event properties are:

  • args – If the handler was bound to the event using bind(event, handler, args) or by passing evt_handlers=[(event, handler, args), ...], where args is a list then there will be one or more optional extra parameters matching the contents of args.


status – The status returned to the peer AE in the N-DELETE response. Must be a valid N-DELETE status value for the applicable Service Class as either an int or a Dataset object containing (at a minimum) a (0000,0900) Status element. If returning a Dataset object then it may also contain optional elements related to the Status (as in DICOM Standard, Part 7, Annex C).

Return type

pydicom.dataset.Dataset or int


NotImplementedError – If the handler has not been implemented and bound to evt.EVT_N_DELETE by the user.
