public class KeystrokeSensor
extends WeatherSensor

A sensor to generate weather events with the keyboard. Instead of reading any sensor values, this sensor reads in the standard input stream. Any data retrievied is stored as the sensor measure. Entering one of the keys 'b' or 'g' results in a weather event to be generated, this weather events is good flag set to false or true, respectively.

Please note that reading in the System.in stream requires a terminal 'return' for flushing.

Field Detail

GOOD

public static final char GOOD

The key for good-weather events.

Constant Field Values

Constructor Detail

KeystrokeSensor

public KeystrokeSensor(Map key)
                throws RemoteException

Constructs a new keystroke sensor. Note that only one keystroke sensor per machine may be present.

Throws:

RemoteException

Method Detail

readSensor

protected double readSensor()

Reads the sensor value. This method checks if data is available on Standard.in. If so, all data is retrieved and the last character immediately before the terminal 'enter' is used as the sensor value.

Specified by:

readSensor in class TimerTaskSensor

See Also:

ConvertToPhysical

validReading

public boolean validReading()

A keystroke sensor is always valid.

goodFromRaw

public boolean goodFromRaw(double raw)

Returns false whenever the argumental value is not identical to the char value GOOD

Overrides:

goodFromRaw in class WeatherSensor
