Update of /cvs-repository/Zope3/src/zope/proxy
In directory cvs.zope.org:/tmp/cvs-serv8556/src/zope/proxy
Modified Files:
introspection.py
Log Message:
In prepration for the upcoming interface changes, I added some
new functions for making interface assertions on instances.
Rather than:
class C:
__class_implements__ = I1, I2
use:
class C:
classProvides(I1, I2)
rather than:
__implements__ = I1, I2
use:
moduleProvides(I1, I2)
rather than:
someinstance.__implements__ = I1, I2
use:
directlyProvides(I1, I2)
Note that interface assertions on persistent objects should be aboided
since the internal representation will change.
Continue to make assertions about the interfaces that class instances
implement the same way:
class C:
__implements__ = I1, I2
I also modified the core software to use the new spellings.
