DerivedMeasurement<A extends Measurement<A>, B extends Measurement<B>> class

A measurement representing two simpler measurements tied together by either multiplication or division.

For example, velocity can be modeled as Distance / Time and Area can be modeled as Distance * Distance.

inherited
toString() → String
A string representation of this object.
inherited
withDefaultUnit(MeasurementInterpreter<DerivedMeasurement<A, B>> interpreter) → DerivedMeasurement<A, B>
