[Triplea-develop] serialVersionUIDs?

[Gansito F. <gan...@gm...>]

Hi all,

I noticed that most classes in TripleA don't have a serialVersionUID, I
was wondering why not?  Wouldn't it help to ensure save game
compatibility if we did have UIDs?

Just a thought,

Hey,

Adding a serialversionuuid wouldn't help much in
making different versions compatable.  

Dagan added serialversionuuid fields to a bunch of
classes because files compiled with eclipse and files
compiled with javac would end up with different
serialversion numbers, even though they were the same
class.  By adding the fields, a developer could load a
saved game with code compiled in eclipse as he could
with code compiled by javac.

The TripleA policy that different versions are not
compatable is because it is too much work.  If we
maintain version compatability we would have to be
careful in what changes in the code, write code to
deal with older and current versions, and test for
compatability.  Rather than do that, we just force
people to upgrade.
