Method Summary

int	getValue()
int	readNewValue() This method reads the current value in decimal measured by the hardware or compute a random value for the simulated sensor, and returns this current value.
void	updateValue() This method reads the current value, controls if this current value is correct depending on the type of the sensor (this value could be between a minimum and a maximum) and if the value is correct, updates the Sensor.value field.

Method Detail

getValue

int getValue()

Returns:

the field value for the object Sensor

readNewValue

int readNewValue()
                 throws HardwareError

This method reads the current value in decimal measured by the hardware or compute a random value for the simulated sensor, and returns this current value.

Returns:

the current value provided by the real or simulated sensor.

Throws:

HardwareError

updateValue

void updateValue()
                 throws SensorValueOutOfRangeException,
                        HardwareError

This method reads the current value, controls if this current value is correct depending on the type of the sensor (this value could be between a minimum and a maximum) and if the value is correct, updates the Sensor.value field.

Throws:

SensorValueOutOfRangeException

HardwareError
