Hi,
One additional piece of information about the classes whose StreamerInfo
are not included in the file. There are actually 2 classes: TkrLayer and
StripId. Both of which are stored in TObjArrays. This is our only use of
TObjArrays. This might be a clue. So, our Event class contains a
TObjArray to store TkrLayers and each TkrLayer contains a TObjArray to
store StripIds.

classes in the file do not seem to get any StreamerInfo information at all
written to the file. I have confirmed this using root's own
TFile.ShowStreamerInfo(). I cannot see any obvious difference between the
classes that get TStreamerInfo and the ones that do not. I have attached
the .h file for one class that does not get included in case you can see
something wrong with it.
