DurationBasedAnimationSpec

interface DurationBasedAnimationSpec<T> : FiniteAnimationSpec<T>

A FiniteAnimationSpec whose forward cycle has a known, fixed duration. Repeating a cycle is only possible when its length is known up front, so repeatable / infiniteRepeatable accept only duration-based specs (springs, which have no fixed cycle, are excluded).

Properties
