pynetdicom.transport.AssociationServer

class pynetdicom.transport.AssociationServer(ae, address, ssl_context=None, evt_handlers=None)

An Association server implementation.

Any attempts to connect will be assumed to be from association requestors.

The server should be started with serve_forever(poll_interval), where poll_interval is the timeout (in seconds) that the select.select() call will block for (default 0.5). A value of 0 specifies a poll and never blocks. A value of None blocks until a connection is ready.

ae

The parent AE that is running the server.

Type

ae.ApplicationEntity

request_queue_size

Default 5.

Type

int

server_address

The (host, port) that the server is running on.

Type

2-tuple

ssl_context

The SSLContext used to wrap client sockets, or None if no TLS is required (default).

Type

ssl.SSLContext or None

__init__(ae, address, ssl_context=None, evt_handlers=None)

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

Parameters

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

• address (2-tuple) – The (host, port) that the server should run on.

• 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 beused (default).

• evt_handlers (list of 2-tuple, optional) – A list of (event, callable), the callable function to run when event occurs.
