pynetdicom._handlers.doc_handle_sop_extended(event: Event, *args: Sequence[Any]) → Dict[UID, bytes][source]

Documentation for handlers bound to evt.EVT_SOP_EXTENDED.

User implementation of this event handler is required only if SOP Class Extended Negotiation is to be supported by the association. If a handler is not implemented and bound to evt.EVT_SOP_EXTENDED then no response will be sent to the SOP Class Extended Negotiation request.

Event

evt.EVT_SOP_EXTENDED

Parameters:

  • event (events.Event) –

    The event representing an association request being received which contains one or more SOP Class Extended Negotiation item. Event attributes are:

    • app_info: the {SOP Class UID : Service Class Application Information} parameter values for the included items, with the service class application information being the raw encoded data sent by the requestor (as bytes).

    • assoc: the Association that is running the service that received the user identity negotiation request.

    • event: the event that occurred as InterventionEvent.

    • timestamp: the date and time that the negotiation request was processed as datetime.datetime.

  • 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.

Returns:

The {SOP Class UID : Service Class Application Information} parameter values to be sent in response to the request, with the service class application information being the encoded data that will be sent to the peer as-is. Return an empty dict if no response is to be sent.

Return type:

dict of pydicom.uid.UID, bytes
