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.

Method Details

evaluate

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.

Overrides:

numInputValues

public int numInputValues()

Description copied from class: PDFFunction

Returns the number of parameters this function takes as input

Overrides:

numInputValues in class PDFFunction

numOutputValues

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.

Overrides:
