hi tim,
query by example is actually a query by id (i'll rename it)
for a minimal solution see QueryByCriteria(Object exampleObj);

Subject: QueryByExample not implemented???
I was just attempting to perform a QueryByExample and have found that the
QueryByExample object does not seem to have been completely implemented
because the "getCriteria" method just returns null.
Now my guess is that this should build Criteria from the example object
passed into the constructor but clearly that is not the case.
Is this mechanism actually working? It doesn't seem to be for me and I have
checked to make sure the object being passed in is non-null and has
attributes set. What I get back is ALL the rows of the table (as objects of
course). Sample code below
Thanks for any help.
Cheers,
Tim
PersistenceBroker broker = null;
try {
broker = PersistenceBrokerFactory.createPersistenceBroker(new
PBKey("my_repository.xml"));
Query query;
if(refIndex == null)
query = null;
else
query = new QueryByExample(refIndex);
Criteria crit = query.getCriteria();
return broker.getCollectionByQuery(query);
} catch (Throwable t) {
t.printStackTrace();
}
