I've asked myself several times how to document this. I've used
different versions:
- "Unique ID for Class Serialization."
- "Class id for Serialization."
and the more descriptive:
/**
* Needed to identify the version of this code when serializing/
deserializing (since Exception is Serializable).
* Note that the value needs to be modified whenever a non
transient field is added or removed in this class.
*/
The last one is the one I prefer (I think) since not everyone knows
about this and it makes it clear that the id needs to be modified
whenever a new field is added/removed.
We could also add a link to some URL describing class serialization.
WDYT?
Thanks
