public class RemoteSensorStub
extends DataValue
implements Reloadable

This class is a parameter stub, intended to bind to a remotely running sensor. Similar to a ParameterStub, it tries to register at the remote data sensor during initialization.

Constant Field Values

listen

private MyRmiListener listen

The rmi-listener & reference watcher for binding to the sensor.

Constructor Detail

RemoteSensorStub

public RemoteSensorStub(Map info)

Constructs a new sensor global. If the sensor this global should wrap could not be found in the properties, the construction fails with an IllegalArgumentException. Additionally, the properties are scanned for the data source key. If this key is not present or maps to an illegal value, it is (re)mapped to DataValue.VALUE. This guarantees that this key is present and points to a allowed value once the construction phase is finished.

Method Detail

rescanned

public double rescanned(String key,
                        String old,
                        String newval)

If the listener reference has changed, we reinit the binding or pass the changed key to the listener properties.

Specified by:

rescanned in interface Reloadable

Overrides:

rescanned in class AbstractParameter

init

public void init()

Initializes this parameter. This means binding to the remote reference.

Specified by:

init in interface Initializable

Overrides:

init in class AbstractParameter

exit

public void exit()

For orderly shutdown, de-register from the binding reference. Simply call the exit method of the listen helper object.

Specified by:

exit in interface ExitCleaning

Overrides:

exit in class AbstractParameter
