Class GpsTimeCorrection

java.lang.Object

fact.filter.GpsTimeCorrection

All Implemented Interfaces:

stream.Processor

public class GpsTimeCorrection
extends Object
implements stream.Processor

This processor handles the Gps time correction. It requires a gps time corrected events file either as URL and will read the Unix time data ( unix time seconds, unix time microseconds ) from that. The corrected time datum is then applied to the corresponding FactEvent processed by the process method.

public GpsTimeCorrection()

Method Detail

process

public stream.Data process(stream.Data item)

This is the method called in the process loop. All it does is to call gpsTimes with the EventNum and get back the teo ints corresponding to the GPS corrected unix time

Specified by:

process in interface stream.Processor

loadGpsTimeCorrection

protected void loadGpsTimeCorrection(stream.io.SourceURL in)

setUrl

public void setUrl(URL url)
