package com.codename1.backend.mongo

A MongoDB client speaking the wire protocol (OP_MSG) directly, with SCRAM-SHA-256 authentication and TLS.

MongoClient opens and pools connections; MongoCollection has the CRUD operations. Documents are Maps -- Bson keeps their key order, which MongoDB requires of a command -- holding strings, numbers, booleans, java.util.Date, byte[], ObjectId, lists and nested maps. Filters and Updates build the query and update documents.

Not supported: mongodb+srv:// seed lists (they need DNS SRV lookups this runtime does not have; list the hosts instead), replica-set failover (the first host that answers is used for everything), SCRAM-SHA-1, X.509 and Kerberos authentication, sessions and multi-document transactions.

    Bson
    BSON, the binary document format MongoDB stores and speaks.
    Bson.Decimal128Bytes
