Class Bson

java.lang.Object

com.codename1.backend.mongo.Bson

public final class Bson
extends Object

BSON, the binary document format MongoDB stores and speaks.

Java	BSON
Double, Float	double
String	string
Map	embedded document (key order kept)
List, Object[]	array
byte[]	binary, generic subtype
ObjectId	ObjectId
Boolean	boolean
Date	UTC datetime
null	null
Integer, Short, Byte	int32
Long	int64

Decoding reads documents into LinkedHashMap, arrays into ArrayList, a timestamp as its Long and a Decimal128 as its sixteen raw bytes in a Bson.Decimal128Bytes; other legacy types are refused.
