    /**

     * Returns whether this Animator has been started and not yet ended. This state is a superset

     * of the state of {@link #isRunning()}, because an Animator with a nonzero

     * {@link #getStartDelay() startDelay} will return true for {@link #isStarted()} during the

     * delay phase, whereas {@link #isRunning()} will return true only after the delay phase

     * is complete.

     * Returns whether this Animator has been started and not yet ended. For reusable

     * Animators (which most Animators are, apart from the one-shot animator produced by

     * {@link android.view.ViewAnimationUtils#createCircularReveal(

     * android.view.View, int, int, float, float) createCircularReveal()}),

     * this state is a superset of {@link #isRunning()}, because an Animator with a

     * nonzero {@link #getStartDelay() startDelay} will return true for {@link #isStarted()} during

     * the delay phase, whereas {@link #isRunning()} will return true only after the delay phase

     * is complete. Non-reusable animators will always return true after they have been

     * started, because they cannot return to a non-started state.

     *

     * @return Whether the Animator has been started and not yet ended.
