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