[ojb-users] sample ExistsCriteria

[Arvind G. <Arv...@PA...>]

How do i check if there are any objects that exists which match a particular
criteria?
 
Is it adviced to use ExistsCriteria or PersistenceBroker.getCount(Query)?
Are there any performance issues with any of these?
 
Is there an example for how to use ExistsCriteria?
