[Zope-CVS] CVS: Products/AdaptableStorage/serial_ofs - MetaTypeClassifier.py:1.10

[Shane Hathaway]

Update of /cvs-repository/Products/AdaptableStorage/serial_ofs
In directory cvs.zope.org:/tmp/cvs-serv30532/serial_ofs

Modified Files:
	MetaTypeClassifier.py 
Log Message:
Provided a way to configure ObjectMappers, with the intent of making
AdaptableStorage easier to explain.  Added IConfigurableObjectMapper
and converted all the mapper setup code to use it.  Included a
checkConfiguration() method which validates the entire object mapper
tree.  Then converted the DBTab-based configuration to use a mapper
factory, which can point to any mapper factory function installed
anywhere.  Tangents to this:

- Refactored Zope2FS and Zope2SQL to use the same code for setting up
mappers, leaving "holes" for the gateways.

- Added connect() and close() methods to ITPCConnection (which doesn't
technically exist yet since I need to choose a name for it. ;-) )

- Factored out common parts of the SQL gateways.

- Implemented the newKey() method of IKeyedObjectSystem, which will
help ZEO environments, in theory.
