 * Service interface with public versions of the protected

 * <p>
 * The important differences between this interface and the
 * <code>URLStreamHandler</code> class are that the <code>setURL</code> method is
 * absent and the <code>parseURL</code> method takes a
 * {@link URLStreamHandlerSetter}object as the first argument. Classes
 * implementing this interface must call the <code>setURL</code> method on the
 * <code>URLStreamHandlerSetter</code> object received in the <code>parseURL</code>
 * method instead of <code>URLStreamHandler.setURL</code> to avoid a
 * <code>SecurityException</code>.
