Hi, List.indexOf(..) is a linear search (unless the list is known to be ordered and you can use binary search). So on average such lookup would resolve ~50% of the objects.
Another way is to query for this object directly against the DB. Yet another is to do an in-memory check of the object against the original SelectQuery qualifier: query.getQualifier().match(object); Neither of the 2 will always be equivalent to List.indexOf(..). After all DB data changes over time, and also SQL and in-memory eval have subtle differences. So make a decision based on the task at hand.
