pynetdicom.transport.ThreadedAssociationServer

class pynetdicom.transport.ThreadedAssociationServer(ae: ApplicationEntity, address: Tuple[str, int], ae_title: str, contexts: List[PresentationContext], ssl_context: Optional[ssl.SSLContext] = None, evt_handlers: List[Union[Tuple[Union[NotificationEvent, InterventionEvent], Callable], Tuple[Union[NotificationEvent, InterventionEvent], Callable, List[Any]]]] = None, request_handler: Optional[Callable[[...], BaseRequestHandler]] = None)[source]

An AssociationServer suitable for threading.

New in version 1.2.

__init__(ae: ApplicationEntity, address: Tuple[str, int], ae_title: str, contexts: List[PresentationContext], ssl_context: Optional[ssl.SSLContext] = None, evt_handlers: List[Union[Tuple[Union[NotificationEvent, InterventionEvent], Callable], Tuple[Union[NotificationEvent, InterventionEvent], Callable, List[Any]]]] = None, request_handler: Optional[Callable[[...], BaseRequestHandler]] = None) → None[source]

Create a new AssociationServer, bind a socket and start listening.

Parameters

  • ae (ae.ApplicationEntity) – The parent AE that’s running the server.

  • address (Tuple[str, int]) – The (host: str, port: int) that the server should run on.

  • ae_title (str) – The AE title of the SCP.

  • contexts (list of presentation.PresentationContext) – The SCPs supported presentation contexts.

  • ssl_context (ssl.SSLContext, optional) – If TLS is to be used then this should be the ssl.SSLContext used to wrap the client sockets, otherwise if None then no TLS will be used (default).

  • evt_handlers (list of 2- or 3-tuple, optional) – A list of (event, callable) or (event, callable, args), the callable function to run when event occurs and the optional extra args to pass to the callable.

  • request_handler (type) – The request handler class; an instance of this class is created for each request. Should be a subclass of BaseRequestHandler.
