java - ネストされたすべての静的クラスをパラメーターとしてメソッド呼び出しに自動的に渡すにはどうすればよいですか?

Question

クラス (以下で定義)内の静的クラスの配列を取得し、Network各クラスの属性classをメソッド呼び出しのパラメーターに渡す方法はありますkryo.registerか?

public class Network {
    // Classes to be transferred between the client and the server
    public static class A {
        public int id;
        public String name;
    }

    public static class B {
        public int id;
        public int x;
        public int y;
    }

    // Rest of the classes are defined over here

    static public void register(EndPoint endPoint) {
        Kryo kryo = endPoint.getKryo();

        // typical way of registering classes so that kryonet can use it
        // kryo.register(A.class);
        // kryo.register(B.class);
        // the rest of the classes are registered with kryonet over here

        // my attempt at solving the question,
        // but for some reason this doesn't work?
        for(Object o : Network.class.getDeclaredClasses()) {
            kryo.register(o.getClass());
        }
    }
}
