Class ProxyQuantityFactory<Q extends javax.measure.Quantity<Q>>

java.lang.Object

tech.units.indriya.quantity.ProxyQuantityFactory<Q>

Type Parameters:

Q - The type of the quantity.

All Implemented Interfaces:

javax.measure.spi.QuantityFactory<Q>

public abstract class ProxyQuantityFactory<Q extends javax.measure.Quantity<Q>>
extends Object
implements javax.measure.spi.QuantityFactory<Q>

A factory producing simple quantities instances (tuples Number/Unit). This implementation of QuantityFactory uses the DynamicProxy features of Java reflection API.

For example:
Quantity m = ProxyQuantityFactory.getInstance(Mass.class).create(23.0, KILOGRAM); // 23.0 kg
Quantity t = ProxyQuantityFactory.getInstance(Time.class).create(124, MILLI(SECOND)); // 124 ms
