AnimationFunction

Type Parameters:

T - the return type of this function

All Known Implementing Classes:

AbstractAnimationFunction, AnimationFunctions.AlphaColorAnimationFunction, AnimationFunctions.ColorFunction, AnimationFunctions.InterpolatedAnimationFunction, AnimationFunctions.RandomAnimationFunction, AnimationFunctions.RepeatedAnimationFunction, AnimationFunctions.ReversedAnimationFunction, AnimationFunctions.SequencedAnimationFunction
```
public interface AnimationFunction<T>
```
This interface describes time-based animation functions by their duration and a mapping from time to arbitrary values. These values are typically attribute values of an animation target, for example the width of a rectangle, the x position of a point, the color of a line, the alpha value of a panel.
For each time in the function's valid time interval, the #valueAt method returns a value that can be used to apply an animation effect in an Animation.

- Method Detail
  - duration
```
long duration()
```
    Returns the length of this function's valid time interval.
    
    Returns:
    
    the length of this function's valid time interval
  - valueAt
```
T valueAt(long time)
```
    Returns the function value at a given time in the valid time interval. The value is undefined for times outside this function's time interval. An implementation may throw an exception, if this method called with a time outside the time interval.
    
    Parameters:
    
    time - the time used to determine the animation effect
    
    Returns:
    
    the function value at the given time
