tec.units.ri.quantity

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

java.lang.Object

tec.units.ri.quantity.DefaultQuantityFactory<Q>

Type Parameters:

Q - The type of the quantity.

All Implemented Interfaces:

javax.measure.spi.QuantityFactory<Q>

public final class DefaultQuantityFactory<Q extends javax.measure.Quantity<Q>>
extends Object

The default factory implementation. This factory provides a default implementation for every AbstractQuantity sub-type. For example:
Quantity m = DefaultQuantityFactory.getInstance(Mass.class).create(23.0, KILOGRAM); // 23.0 kg
Quantity m = DefaultQuantityFactory.getInstance(Time.class).create(124, MILLI(SECOND)); // 124 ms
