[Zodb-checkins] CVS: Zope3/src/zope/interface - implementor.py:1.3

[Jim Fulton]

Update of /cvs-repository/Zope3/src/zope/interface
In directory cvs.zope.org:/tmp/cvs-serv20001/src/zope/interface

Modified Files:
	implementor.py 
Log Message:
Modified the ImplementorRegistry so we can pass a dictionary to be
used to store regtered data. This allows us to pass a PersistentDict
and thus get the registry to work with persistence.

Added a getRegistered method, which we need to get data for a specific
interface without "deheriting" data for more specific interfaces.
