```
public class ArrayFunction
extends PDFFunction
```
An array function is not one of the built-in PDF function types. Rather, it is a cover function for the case where an array of n Functions is used as a single input, n output function. Can be used, for example, to declare completely different functions for each channel in a colorspace.

```
public float[] evaluate(float[] inputs)
```
    Description copied from class: PDFFunction
    
    Evaluate the function. Note that the return value array is reused, so if you need to save the results around for any length of time, you should copy them out.

public int numInputValues()
```
    Description copied from class: PDFFunction
    
    Returns the number of parameters this function takes as input

```
public int numOutputValues()
```
    Description copied from class: PDFFunction
    
    Returns the number of values this function returns. Should be overridden by subclasses that don't require outputRange.
