/**

 * 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.
