A class comment might help here, but the first commit notice
explains it. I don't think this is currently used, but I could
see possible uses for it in the future.
It is possible to translate our MCM update stream into a change
set update stream, and Andreas has done this in the past. A
change set update stream is much more stable and reproducable (not
to mention faster) than an MCM stream, so there could be value
(Note to self - I think that Edgar De Cleene provide background
on Andreas' change update stream the last time I asked about it,
I'll have to dig through the email archives to find his notes.).
Here is the commit notice:
Time: 6 December 2013, 5:07:25.049 pm
Create an UpdateStreamDownloader class to host Utilities class>>'fetching updates' methods.
Utilities class side methods are copied as is to UpdateStreamDownloader class side with original authors/stamps
The pre-trunk updateFromServer version has been restored.
In the future, the UpdateStreamDownloader could create instances if this makes sense...
But since this is essentially unused, it might as well not happen.
