All Implemented Interfaces:

Cloneable, EventListener, DataListener, ErrorDependingParameter, Parameter, Value, ExitCleaning, Initializable, LocalizedSupplying, PropertySupplying, Reloadable, ResourceSupplying

Direct Known Subclasses:

RemoteSensorAverage, RemoteSensorMaximum

public abstract class RemoteSensorStatistic
extends SensorStatistic
implements Reloadable

This value registers to a sensor that is a RmiDataCaster. DataEvents received must be RawDataEvents. From these, the physical value is added to the underlying StatisticValue. Concrete subclasses may return average or min/max of accumulated data.

Note that this class can only work within the MasterMind or CCDMaster, the latter only if the averageing thread is reset by an error-event generated by the CCDMaster.

RemoteSensorStatistic(Map info) Constructs a new sensor statistic.

Method Summary

void	exit() For orderly shutdown, de-register from the binding reference.
void	init() Initializes this parameter.
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.

Field Detail

Constructor Detail

RemoteSensorStatistic

protected RemoteSensorStatistic(Map info)

Constructs a new sensor statistic. Sensor data is gathered at every call to SensorStatistic.dataAvailable(stella.DataEvent)

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
