Re: [hibernate-dev] Fail fast feature for Hibernate Validator
That or slowish validations.
One typical use case is that:
if ( validator.validate(customer, StraightToValidationScreen.class).size() >0 ) {
//manual process
}
else {
//automatic process
}
BTW, I've committed a non scientific perf test that shows an average of 5x perf
improvement on an object graph of 5 object (one master and 4 children) and 4 constraints
on A and 3 on B. Around 22ms vs 120 ms. (log4j logs set to ERROR). The perf change is
visible even on smallish graphs.
It can be worthwhile.

What would be the usecase? Saving time in large object graphs where I
am only interested in whether there is a
failure at all? You really need LARGE object graphs to make this worth while.
