All Known Implementing Classes:

AngleAnimator, BasicAnimator, CompoundAnimator, DoubleAnimator, FlyToFlyViewAnimator, FlyToFlyViewAnimator.FlyToElevationAnimator, FlyToFlyViewAnimator.OnSurfacePositionAnimator, FlyToOrbitViewAnimator, FlyToOrbitViewAnimator.OnSurfacePositionAnimator, KeepingObjectsInView.ViewAnimator, KMLFlyViewController.FlyToLookAtAnimator, KMLOrbitViewController.EyePositionAnimator, MoveToDoubleAnimator, MoveToPositionAnimator, OrbitViewCenterAnimator, OrbitViewEyePointAnimator, OrbitViewMoveToZoomAnimator, PositionAnimator, RotateToAngleAnimator, ViewElevationAnimator
```
public interface Animator
```
The Animator interface provides a way to iterate through a series of values. It can be used with a simple interpolation function, or something more elaborate. The PropertyAccessor class and its interfaces can be used to agnostically attach to data members of any class.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`boolean`	`hasNext()`	Returns `true` if the `Animator` has more elements.
`void`	`next()`	Iterates to the next value.
`void`	`set(double interpolant)`	Set the value of the attached property to the value associated with this interpolant value.
`void`	`start()`	Starts the `Animator`.
`void`	`stop()`	Stops the `Animator`.

- Method Detail
  - next
```
void next()
```
    Iterates to the next value. The implementation is expected to apply that next value to the property it is attached to.
  - start
```
void start()
```
    Starts the Animator. The implemenation should return true from hasNext
  - stop
```
void stop()
```
    Stops the Animator. The implmenentation should return false from hasNext
  - hasNext
```
boolean hasNext()
```
    Returns true if the Animator has more elements.
    
    Returns:
    
    true if the Animator has more elements.
  - set
```
void set(double interpolant)
```
    Set the value of the attached property to the value associated with this interpolant value.
    
    Parameters:
    
    interpolant - A value between 0 and 1.
