22/**
23 * Delegate implementing the native methods of android.animation.PropertyValuesHolder
24 *
25 * Through the layoutlib_create tool, the original native methods of PropertyValuesHolder have been
26 * replaced by calls to methods of the same name in this delegate class.
27 *
28 * Because it's a stateless class to start with, there's no need to keep a {@link DelegateManager}
29 * around to map int to instance of the delegate.
30 *
31 * The main goal of this class' methods are to provide a native way to access setters and getters
32 * on some object. In this case we want to default to using Java reflection instead so the native
33 * methods do nothing.
