Examples of org.nutz.mongo.entity.MongoEntity.formatObject()

org.nutz.mongo.entity.MongoEntity.formatObject()
格式花参考对象
参考对象用来查询和设置，实现类应该根据自己的具体设置修改参考对象的键值。 @param o 参考对象 @return DBObject 以供驱动程序使用

    // 获得集合
    String collName = moe.getCollectionName(q);
    if (db.collectionExists(collName)) {
      DBCollection coll = db.getCollection(collName);
      // 将 ref 对象转换成 DBObject
      DBObject dbRef = moe.formatObject(q);


      // 执行删除
      return coll.remove(dbRef);
    }
    return null;
