[Zope-Checkins] CVS: Zope3/lib/python/Zope/App/ZopePublication/TraversalViews - AbsoluteURL.py:1.1 ObjectName.py:1.1 __init__.py:1.1 config.zcml:1.1

[Steve Alexander]

Update of /cvs-repository/Zope3/lib/python/Zope/App/ZopePublication/TraversalViews
In directory cvs.zope.org:/tmp/cvs-serv4064/TraversalViews

Added Files:
	AbsoluteURL.py ObjectName.py __init__.py config.zcml 
Log Message:
Moved AbsoluteURL into a TraversalViews package, to cover both
AbsoluteURL and also ObjectName.

ObjectName is sort of like a minimal version of AbsoluteURL in that it
gets you the name the current object was traversed via.
It can be used as a view, as @@object_name or by getting an adapter 
for IObjectName, as in getAdapter(obj, IObjectName)().

Also, I added a __call__ method to IAbsoluteURL, as it was needed for
security declarations.
