[Zope] objectIds vs. objectValues vs. objectItems

[Andy McKay]

Use the source luke.

http://www.zopezen.org/ZopeZen/Source/lib/python/OFS/%7eObjectManager.py#362

An object manager (folder) maintains a list of the sub objects it has.

objectIds - a list of those objects, fastest

objectValues - returns each object from the list in objectIds, meaning its
slower than objectIds, but more info.

objectItems - returns a set of pairs of id and object, kind of like the
first two rolled into one.

Cheers.
