Method Detail

create

static ClipInterpolator create(KeyFrame[] keyFrames,
                               long[] keyFrameTicks)

getRealKeyFrameCount

static int getRealKeyFrameCount(KeyFrame[] keyFrames)

Figures out the number of "real" key frames. The user may not have specified the "zero" key frame, in which case we end up inferring an additional zero key frame on the array.

Parameters:

keyFrames - The key frames. Must not be null.

Returns:

The "real" number of key frames

setKeyFrames

abstract ClipInterpolator setKeyFrames(KeyFrame[] keyFrames,
                                       long[] keyFrameTicks)

Changes the keyframes. The optimal implementation for the new keyFrames might be different. For this reason, setKeyFrames returns a ClipInterpolator implementation with the updated values. This can either be the same object or a newly created one.

Parameters:

keyFrames - The new sorted array of keyframes of this clip

keyFrameTicks - tick duration of corresponding keyFrames

Returns:

The ClipInterpolator implementation to use after changing the keyframes.

interpolate

abstract void interpolate(long ticks)

validate

abstract void validate(boolean forceSync)
