Description Michael Zalewski 2003-08-07 04:01:50 UTC
Every node in a POIFS (OLE Structured File) has an associated 'storage Class 
ID', which is stored on the node from 0x50 - 0x5f. Also, 0x60 - 0x63 is 'User 

Provide an API to access the storage Class ID.

This may or may not be related to 

Excel 97 and above store the CLSID {00020820-0000-0000-C000-000000000046} at 
the root property. A new workbook created from HSSF does not store this. This 
patch does not change HSSF, but provides an API which HSSF might use to set 
this value.

Can you provide a patch against the REL_2_BRANCH. . This should go in the release as its pretty 
serious.  (anyone disagree?)
Comment 3 Michael Zalewski 2003-08-07 04:23:12 UTC
Hmmm. Might actually be against REL_2_BRANCH. I just pulled the default branch 
and made it this evening.

But it don't have to go into Release 2. It really has no effect on HSSF, or 
anything else. If it were me, I would wait for Release 3, unless someone uses 
it to fix an actual problem.

However, the new TestCase is against org.apache.poi.hpsf.ClassID, which 
formerly had no testcase.
Comment 4 Andy Oliver 2003-08-07 15:01:44 UTC
yes the head is rel 3.  I'd like to use it for rel 2.

I told Kirill on the other bug that he was too late for 2.0. But this one has
been around for a while, and Andy mentioned he liked it for 2.0. What say folks,
should we add this to 2.0? Since there is a testcase, maybe we should?

Comitted. both to Branch and HEAD. Please cross-check, ClassID.java from the
branch pathc didnt apply cleanly to HEAD, so I took that out of the HEAD patch
attached to this bug. All tests pass in branch. The relevant tests pass on HEAD. 

Kirill, if you can get the gettter/setter in by end of friday, it might still go
into the next release. Reopen this bug when you do. Thanks.
