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

event (events.Event) –
The event representing a service class receiving a N-ACTION request message.
context: the presentation context the request was sent under as a
request: the received
action_information: the decoded
Datasetcontained within the N-ACTION request’s Action Information parameter. Because pydicom uses a deferred read when decoding data, if the decode fails the returned
Datasetwill only raise an exception at the time of use.
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
listthen there will be one or more optional extra parameters matching the contents of args.
status (pydicom.dataset.Dataset or int) – The status returned to the peer AE in the N-ACTION response. Must be a valid N-ACTION status value for the applicable Service Class as either an
Datasetobject containing (at a minimum) a (0000,0900) Status element. If returning a
Datasetobject then it may also contain optional elements related to the Status (as in DICOM Standard, Part 7, Annex C).
dataset (pydicom.dataset.Dataset or None) – If the status category is ‘Success’ or ‘Warning’ then a
Datasetcontaining elements for the response’s Action Reply conformant to the specifications in the corresponding Service Class.
If the status category is not ‘Success’ or ‘Warning’ then
NotImplementedError – If the handler has not been implemented and bound to
evt.EVT_N_ACTIONby the user.
