This always makes my head hurt, but I will take a stab at it.
invalidate: tosses the snapshot, affects all editing contexts.
Forces the data to be refetched from the database.
refault: changes the eo back into a fault in the EC. Depending on
the EC's fetch timestamp and the snapshot's age, it _may_ go back to
the database for fresh data when the fault is fired. I think this
discards any uncommited changes.
refresh: pretty much the same as refault, but merges uncommitted
changes back into eo.
I have found problems with refault() and refresh() and created my own
versions that you can find in EOObject in our GVCEOFExtensions
framework. Sorry, but I don't recall the details right now.

What is the difference between Invalidating an object versus

It seems that some of the methods call the others. Any commentary
on which should be used and when would be appreciated. Thanks in
advance
