    • withCodecRegistry

      MongoDatabase withCodecRegistry(CodecRegistry codecRegistry)
      Create a new MongoDatabase instance with a different codec registry.

      The CodecRegistry configured by this method is effectively treated by the driver as an instance of CodecProvider, which CodecRegistry extends. So there is no benefit to defining a class that implements CodecRegistry. Rather, an application should always create CodecRegistry instances using the factory methods in CodecRegistries.

      Parameters:
      codecRegistry - the new CodecRegistry for the database
      Returns:
      a new MongoDatabase instance with the different codec registry

      MongoDatabase withWriteConcern(WriteConcern writeConcern)
      Create a new MongoDatabase instance with a different write concern.
      Parameters:
      writeConcern - the new WriteConcern for the database
