That doesn't seem like something you should be adding to the docs I think?

This is basically handed off to individual implementations (`getData` is
abstract), for example in `FloatBinding`:
private static final ListenerManager<Number, FloatBinding> LISTENER_MANAGER
= new ListenerManager<>() {
@Override
protected Object getData(FloatBinding instance) {
return instance.listenerData;
}
@Override
protected void setData(FloatBinding instance, Object data) {
instance.listenerData = data;
}
};
I've updated the docs for the abstract methods to include that these should
throw NPE when `instance` is `null`.
