类 BsonConvert

java.lang.Object

org.redkale.convert.Convert<BsonReader,BsonWriter>

org.redkale.convert.bson.BsonConvert

public final class BsonConvert
extends Convert<BsonReader,BsonWriter>

 BSON协议格式:
  1). 基本数据类型: 直接转换成byte[]
  2). SmallString(无特殊字符且长度小于256的字符串): length(1 byte) + byte[](utf8); 通常用于类名、字段名、枚举。
  3). String: length(4 bytes) + byte[](utf8);
  4). 数组: length(4 bytes) + byte[]...
  5). Object:
      1. realclass (SmallString) (如果指定格式化的class与实体对象的class不一致才会有该值, 该值可以使用@ConvertEntity给其取个别名)
      2. 空字符串(SmallString)
      3. SIGN_OBJECTB 标记位，值固定为0xBB (short)
      4. 循环字段值:
          4.1 SIGN_HASNEXT 标记位，值固定为1 (byte)
          4.2 字段类型; 1-9为基本类型和字符串; 101-109为基本类型和字符串的数组; 127为Object
          4.3 字段名 (SmallString)
          4.4 字段的值Object
      5. SIGN_NONEXT 标记位，值固定为0 (byte)
      6. SIGN_OBJECTE 标记位，值固定为0xEE (short)
