Class Measure<T extends Unit>

java.lang.Object
  com.antelmann.math.Measure<T>

All Implemented Interfaces:

Measurable, Serializable, Comparable<Measure<T>>

public class Measure<T extends Unit>
extends Object
implements Measurable, Comparable<Measure<T>>

represents some immutable generic measure to serve as a basis for sub-classing; this class itself provides type safety for the unit in use. A measure is typed to its unit, so that a programmer can ensure that only a measure of a certain type is used when setting a value.
