                   FinchSensor obj2)

Compare two FinchSensor objects: acceleration magnitude

Parameters:

obj1 - FinchSensor object

obj2 - FinchSensor object

Returns:

1 if obj1 is larger than obj2, 0 if they are equal and -1 if obj1 is less than obj1

doubleValue

public double doubleValue(FinchSensor obj)

Description copied from class: SensorComparator

Return the value of obj that is specified by the instantiation of the child class.

Specified by:

doubleValue in class SensorComparator

Parameters:

obj - A FinchSensor sample

Returns:

The value of the sensor as a double

toString

public java.lang.String toString()

Description copied from class: SensorComparator

Force the child class to return a string that describes itself.

Specified by:

toString in class SensorComparator

Returns:

A string describing this comparator
