[Zope-CVS] CVS: Products/AdaptableStorage/mapper/interfaces - IAspectSerializer.py:1.2 IObjectSerializer.py:1.2

[Shane Hathaway]

Update of /cvs-repository/Products/AdaptableStorage/mapper/interfaces
In directory cvs.zope.org:/tmp/cvs-serv31552/mapper/interfaces

Modified Files:
	IAspectSerializer.py IObjectSerializer.py 
Log Message:
Added OptionalAspect, a wrapper that disables an aspect if it can't
serialize the object.  This involved refactoring the IAspectSerializer
and IObjectSerializer interfaces.  Thanks, Christian, for discovering
the need for this.
