Interface Function

public interface Function

An interface to represent the math function concept. In this particular case, as it is mainly used to implement animation in CustomAnimation, the passed in parameters are currentStep and totalSteps respectively.Step is current step, so currentStep/totalSteps will be x. The value of x is between 0 and 1. We expect the returned y is between 0 and 1 as well.

Method Summary

double

calculate(int currentStep, int totalSteps) Calculation y = f(x), x = currentStep / totalSteps.

Method Detail

calculate

double calculate(int currentStep,
                 int totalSteps)

Calculation y = f(x), x = currentStep / totalSteps. x belongs [0, 1] and y belongs to [0, 1]

Parameters:

currentStep - current step index

totalSteps - total steps

Returns:

a double value between 0 and 1.
