public class LazyBSONObject extends Object implements BSONObject
BSONObject backed by a byte buffer that lazily provides keys and values on request. This is useful for transferring
BSON documents between servers when you don't want to pay the performance penalty of encoding or decoding them fully.| Constructor and Description |

LazyBSONObject(byte[] bytes,
