DefaultQuantityFactory (Units of Measurement Reference Implementation 2.2.2 API)

java.lang.Object
- tech.units.indriya.quantity.DefaultQuantityFactory<Q>

Type Parameters:

Q - The type of the quantity.

All Implemented Interfaces:

QuantityFactory<Q>
```
public class DefaultQuantityFactory<Q extends Quantity<Q>>
extends Object
implements 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
