Current JavaFX doc available from Oracle at http://docs.oracle.com/javase/8/javafx/api/ is missing classes use information.
Take a look at the JDK 8 doc page for the class java.util.Optional, http://docs.oracle.com/javase/8/docs/api/java/util/Optional.html
The page header contains the USE tab.
We can find all places where this class in in use in the public Java API. The USE page can be reached directly at the URL http://docs.oracle.com/javase/8/docs/api/java/util/class-use/Optional.html
Now take a look at the javadoc page for class javafx.animation.Interpolator, http://docs.oracle.com/javase/8/javafx/api/javafx/animation/Interpolator.html.
The page header is missing the USE tab.
This makes more difficult to find out where the Interpolator class from JavaFX is used in the public JavaFX API.
The documentation from JavaFX needs to be recompiled with the -use flag.
