[MOBY-dev] Using CentralDigestCachedImpl....

[Andreas Groscurth]

Hi Paul,

thanks for the message...

So do i understand it correctly ? I create such Registry object and then I 
pass that instance to any of the org.biomoby.shared.data.*.

e.g. new MobyDataObject( "something", "anything", registry) 

?

thanks
andreas
