FrequencyMeasurerangeSubclassinverseA UnaryConstantFunction of continuous time. All instances of this Class map a time quantity into another ConstantQuantity such as temperature. For example, 'the temperature at the top of the Empire State Building' is a TimeDependentQuantity since its value depends on the time

UnitOfMeasureSubtractionFnMeasureFnA standard of measurement for some dimension. For example, the Meter is a UnitOfMeasure for the dimension of length, as is the Inch. There is no intrisic property of a UnitOfMeasure that makes it primitive or fundamental; rather, a system-of-units (e.g. SystemeInternationalUnit) defines a set of orthogonal dimensions and assigns units for each
