Re: "Volatile" EOF classes

Hi Randy,

Invalidating all objects in the root store is the sledgehammer  
approach! ..... the gentler way to achieve what you want is as follows:

Each time you want to fetch latest database state, simply create a  
fresh editing context, setFetchTimestamp() to current time and fetch  
objects into the editing context. Those objects will be as fresh as  
the timestamp you set on the ec.... and the EOF object store cache  
snapshots automatically get updated so other ec's benefit too.

You can also alternatively do a refaultAllObjects and subsequent  
setFetchTimestamp on an existing editing context.

See EOEditingContext API docs for more info.

HTH,

Regards, Kieran
