[Zope-CVS] CVS: Products/AdaptableStorage/serial_std - AnyObjectSerializer.py:1.1 public.py:1.6

[Shane Hathaway]

Update of /cvs-repository/Products/AdaptableStorage/serial_std
In directory cvs.zope.org:/tmp/cvs-serv10661/serial_std

Modified Files:
	public.py 
Added Files:
	AnyObjectSerializer.py 
Log Message:
Added two mappers to Zope2FS for serializing any kind of object.  If no mapper
is provided for a class, the database falls back to a default mapper--either
the "fileish" or the "folderish" mapper.

... which is *really cool*. :-)  I've been trying to achieve this in a clean
way for months.  (Deeeeep, loooonnnnnggggg sigh of relief!)
