The shared serialization delegate for this package.
Implementation notes
This class wraps the object being serialized, and takes a byte representing the type of the class to be serialized. This byte can also be used for versioning the serialization format. In this case another byte flag would be used in order to specify an alternative version of the type format. For example
JAPANESE_DATE_TYPE_VERSION_2 = 21.In order to serialise the object it writes its byte and then calls back to the appropriate class where the serialisation is performed. In order to deserialise the object it read in the type byte, switching in order to select which class to call back into.
The serialisation format is determined on a per class basis. In the case of field based classes each of the fields is written out with an appropriate size format in descending order of the field's size. For example in the case of
LocalDateyear is written before month. Composite classes, such asLocalDateTimeare serialised as one object.This class is mutable and should be created once per serialization.
