Field Detail

log

private final org.apache.commons.logging.Log log

pointValues

private final java.util.List<PointValueTime> pointValues

State field. The point values that have accumulated so far. Each call to pointChanged will drop off the values beyond the duration.

eventActive

private boolean eventActive

State field. Whether the state has been detected or not. This field is used to prevent multiple events being raised during the duration of a single state detection.

eventActiveTime

private long eventActiveTime

Method Detail

getMessage

public com.serotonin.web.i18n.LocalizableMessage getMessage()

Specified by:

getMessage in class PointEventDetectorRT

isEventActive

public boolean isEventActive()

initialize

public void initialize()

Specified by:

initialize in interface com.serotonin.util.ILifecycle

Overrides:

pointChanged

public void pointChanged(PointValueTime oldValue,
                         PointValueTime newValue)

Description copied from interface: DataPointListener

This method is called every time the point gets a value that is different from its previous value (except for its initialization). This includes when the point is set, if the set changes the point's value.

Specified by:

pointChanged in interface DataPointListener

Overrides:

pointChanged in class PointEventDetectorRT

pointChanged

private void pointChanged(long time,
                          PointValueTime value)

scheduleTimeoutImpl

public void scheduleTimeoutImpl(long fireTime)

Specified by:

scheduleTimeoutImpl in class TimeoutDetectorRT

removeOldPointValues

private void removeOldPointValues(long time)
