Which objects are stored by TFile::Write()?

Hello!

Is there any scheme explaining which objects are stored by TFile::Write()
and which have to be written by the object's ->Write()?

I (after quite some time) found that e.g. TH1's are written
automatically and TText's aren't.

The TFile reference says on Write():
[...] 
*-*  Loop on all objects in memory (including subdirectories)
*-*  A new key is created in the KEYS linked list for each object
*-*  The list of keys is then saved on the file (via WriteKeys)
*-*  as a single data record
[...] 

What is meant by 'all objects' in this case?


Thanks
	Robert
