Package org.vanted.animation.loopers

Class SwingLooper

java.lang.Object

org.vanted.animation.loopers.Looper

org.vanted.animation.loopers.SwingLooper

public class SwingLooper
extends Looper

Reverses the animation after it goes forward. (Reverses when the loop number is an odd number)
TODO: The SwingLooper only behaves properly for loop durations that are longer than the largest time value in the animation's data point list.

findPreviousIndex

public <V,
T extends TimePoint<V>> int findPreviousIndex(List<T> dataPoints,
int oldPreviousIndex,
int currentLoopNumber,
double time)

Description copied from class: Looper

(Provided this method is not overridden) Finds the largest index, from a set of data points, who's getTime() method is <= time.

Overrides:

findPreviousIndex in class Looper

Type Parameters:

V - The type of data value that the data point holds.

T - The type of data point that the interpolator is interpolating for.

Parameters:

dataPoints - The set of data points that the interpolator is interpolating on

oldPreviousIndex - The old index that was being used before this method was called

currentLoopNumber - The current loop number of the animation

time - The time that has elapsed since the start of the animation loop.

Returns:

The largest index from a set of data points, who's getTime() return value is <= time.

TimePoint.getTime()

getTimeSinceStartOfLoop

public double getTimeSinceStartOfLoop(int currentLoopNumber,
double startTime,
double loopDuration,
double time)

Description copied from class: Looper

Calculates the time since the start of the loop

Overrides:

getTimeSinceStartOfLoop in class Looper

Parameters:

currentLoopNumber - The animation's loop number.

Returns:

The time since the start of the animation's current loop.

getNextLoopPreviousIndex

public <V,
T extends TimePoint<V>> int getNextLoopPreviousIndex(List<T> dataPoints,
int newLoopNumber)

Description copied from class: Looper

Specifies what the previousIndex animation should be set to when it starts a new loop.

Overrides:

getNextLoopPreviousIndex in class Looper

Parameters:

dataPoints - The set of data points that the interpolator is interpolating on.

newLoopNumber - The animation's new loop number.

Returns:

The new previousIndex value of the Animation.
