public class AlienGPIOSession
extends AbstractServerSocketSensorSession

This is a session that listens for events on an Alien reader's IOStream. It opens up a port on the serverSocketPort and the Alien reader can then send IO events to that port. The session needs to be initialized before the connect method can be called so that it can get the initial state of the external inputs and outputs. This session should normally be started up as part of an interactive session (Alien9800ReaderSession).

AlienGPIOSession

public AlienGPIOSession(AbstractSensor<?> sensor,
                        java.lang.String ID,
                        int serverSocketPort,
                        AlienIOListMessageParsingStrategy parsingStrategy)

Constructor

Parameters:

sensor - The sensor this session belongs to

ID - The ID of this session

serverSocketPort - The port to open up a listening socket on

parsingStrategy - The strategy to use to parse strings into AlienGPIOMessages (e.g. text, terse, xml, custom)

Method Detail

initialize

public void initialize(Alien9800ReaderSession interactiveSession)
                throws CannotExecuteException

Initialize must be called before connect can be called

Parameters:

interactiveSession - The live interactive session used to query the reader for it's current state of external input and output

Throws:

CannotExecuteException - if there was a problem when the initialization was attempted.

disconnect

public void disconnect()

Description copied from class: SensorSession
