stella.sensor
Class Meteorology

java.lang.Object
  stella.sensor.Meteorology

All Implemented Interfaces:

Comparable<Meteorology>

public class Meteorology
extends Object
implements Comparable<Meteorology>

Class that reads weather ascii files in the format:

   dd.MM.yy HH:mm:ss[*] val[*] ...val...
   

The first two colums are the date, followed by an asterisk, if overall weather was bad. Then, individual sensor averages follow, again marked with an asterisk, if currently bad or in retardation. A exclamation mark signals sensor stalled, the bad/good flag is than taken from the prior reading.

Nested Class Summary

static class	Meteorology.Robotel Reads the robotel weather data and does some statistic.
static class	Meteorology.Stella Reads the Tenerife weather data and does some statistic.
