class comments on all of these.

Why are the first 2 classes and the last one a struct?

[tzik, 2011/07/01 01:27:05]

Done. That is forgotten to modify. Thanks.

[Evan Stade, 2011/06/28 17:36:49]

I think this warrants its own file

[tzik, 2011/07/01 01:27:05]

Done.

[Evan Stade, 2011/06/28 17:36:49]

I don't see where this is used

[tzik, 2011/07/01 01:27:05]

Done.

+  typedef quota::QuotaManager::OriginInfoTableEntry OriginInfoTableEntry;

[Evan Stade, 2011/06/28 17:36:49]

or this one

[tzik, 2011/07/01 01:27:05]

Done.

+  typedef quota::QuotaManager::QuotaTableEntries QuotaTableEntries;
+  typedef quota::QuotaManager::OriginInfoTableEntries OriginInfoTableEntries;

[Evan Stade, 2011/06/28 17:36:49]

I think you should remove this typedef and if you want to reduce verbosity in
the c++ file, you can use `using`.

[tzik, 2011/07/01 01:27:05]

Did you mean "using quota::QuotaManager::QuotaTableEntries;"?
That is allowed for only subclass of QuotaManager.
Or did you mean "using quota::QuotaManager;"?
