PrimitiveFunction (ojAlgo 47.2.0 API)

java.lang.Object
- org.ojalgo.function.FunctionSet<Double>
- - org.ojalgo.function.PrimitiveFunction

```
public final class PrimitiveFunction
extends FunctionSet<Double>
```
Only the primitive parameter (double) methods are actually implemented. The methods with the reference type parameters (Double) should delegate to the primitive methods (and do nothing else). The various implementations should delegate as much as possible to Math and/or built-in Java operators.
