Keyframe<T> class abstract

An abstract interface for keyframes in timeline animations.

A keyframe defines how to compute a value at a specific point in a timeline animation. Different implementations provide different interpolation strategies (absolute, relative, or static).

Type Parameters

• T - The type of value this keyframe produces.

Overview

Use Keyframe implementations like AbsoluteKeyframe, RelativeKeyframe, or StillKeyframe to build complex timeline animations with TimelineAnimation.

See also:

• AbsoluteKeyframe - Animates between explicit start and end values.
• RelativeKeyframe - Animates from the previous keyframe's end value.
• StillKeyframe - Holds a value without animating.

Implementers

• AbsoluteKeyframe
• RelativeKeyframe
• StillKeyframe
