javax.measure.spi.QuantityFactory<Q>
public class DefaultQuantityFactory<Q extends javax.measure.Quantity<Q>> extends Object implements javax.measure.spi.QuantityFactory<Q>
A factory producing simple quantities instances (tuples Number/ Unit).
For example:
Mass m = DefaultQuantityFactory.getInstance(Mass.class).create(23.0, KILOGRAM); // 23.0 kg
Time m = DefaultQuantityFactory.getInstance(Time.class).create(124, MILLI(SECOND)); // 124 ms
