/**
 * <code>RMIClassLoaderSpi</code> is the service provider interface for
 * <code>RMIClassLoader</code>.
 *
 * In particular, an <code>RMIClassLoaderSpi</code> instance provides an
 * implementation of the following static methods of
 * <code>RMIClassLoader</code>:
 *
 * <ul>
 *
 * <li>{@link RMIClassLoader#loadClass(URL,String)}
 * <li>{@link RMIClassLoader#loadClass(String,String)}
 * <li>{@link RMIClassLoader#loadClass(String,String,ClassLoader)}
 * <li>{@link RMIClassLoader#loadProxyClass(String,String[],ClassLoader)}
 * <li>{@link RMIClassLoader#getClassLoader(String)}
 * <li>{@link RMIClassLoader#getClassAnnotation(Class)}
 *
 * </ul>
 *
 * When one of those methods is invoked, its behavior is to delegate
 * to a corresponding method on an instance of this class.
 * The details of how each method delegates to the provider instance is
 * described in the documentation for each particular method.
 * See the documentation for {@link RMIClassLoader} for a description
 * of how a provider instance is chosen.
