public class SmartOptionalSerializer<T>
extends AbstractSmartSerializer<java.util.Optional<T>>

Generic serializer for an Optional object using another serializer. In general, it is recommended not to serialize absent values, if possible. Please note that in the case where an absent value is meaningful, write(Optional, DataOutput) will add one byte to the serialized value when present and encode an absent value as a single byte.
