That's a shame, it's a real disadvantage not having that simple
functionality.
Thanks for your example, although I found it a little difficult to
understand it completely. Are you suggesting having an entry in the
cache with a key string "allKeys" which maps to a List of keys
belonging to all the other entities in the cache? Would this allow me
to iterate through the keys, saving the entity to the datastore and
then removing the entry from the cache?
Also what is the "putIfUntouched" statement for?
Thanks again
