Method Details [hide private]

__init__(self, server_name, xml_description_filename, max_age=1800, receive_notify=True)
(Constructor)

source code 

Constructor for the SSDPServer class.

Parameters:
  • server_name (string) - server name
  • xml_description_filename () - XML description filename
  • max_age (integer) - max age parameter, default 1800.
  • receive_notify (boolean) - if False, ignores notify messages
Overrides: object.__init__

is_known_device(self, usn)

source code 

Returns if the device with the passed usn is already known.

Parameters:
  • usn (string) - device's usn
Returns: boolean
True if it is known

subscribe(self, name, callback)

source code 

Subscribes a callback for an event.

Parameters:
  • name (string) - name of the event. May be "new_device_event" or "removed_device_event"
  • callback (callable) - callback

unsubscribe(self, name, callback)

source code 

Unsubscribes a callback for an event.

Parameters:
  • name (string) - name of the event
  • callback (callable) - callback

register_device(self, device)

source code 

Registers a device on the SSDP server.

Parameters:
  • device (Device) - device to be registered

_datagram_received(self, data, (host, port))

source code 

Handles a received multicast datagram.

Parameters:
  • data (string) - raw data
  • host (string) - datagram source host
  • port (integer) - datagram source port

_discovery_request(self, headers, (host, port))

source code 

Processes discovery requests and responds accordingly.

Parameters:
  • headers (dictionary) - discovery headers
  • host (string @type port integer) - discovery source host
  • port - discovery source port

_notify_received(self, headers, (host, port))

source code 

Processes a presence announcement.

Parameters:
  • headers (dictionary) - notify headers
  • host (string) - notify source host
