Message Pack Java 0.6.Xメッセージパッケージクラスを使用

注釈の使用  @Message  自分のクラスのオブジェクトをシーケンス化することができます publicフィールド.

複数のオブジェクトを順番にシーケンス化したい場合は、   Packer  および   Unpacker  複数のオブジェクト.
なぜなら  MessagePack.write(Object)  および  read(byte[])  実際には毎回呼び出して作成しました  Packer  および  Unpacker  オブジェクト.
使うために  Packer  および   Unpacker  オブジェクト、呼び出してください  createPacker(OutputStream) および   createUnpacker(InputStream) .
