[hibernate-issues] [Hibernate-JIRA] Commented: (HV-381) Provide a fail fast switch to stop processing constraints on first failure

Kevin Pollet commented on HV-381:
---------------------------------

First off all it's just my opinion :)

Using {{failFast()}} instead of {{failFast(boolean)}} can be confusing if people wants to disable failFast locally on the Validator with {{usingContext}} method. Another point, if people use {{failFast(int maxFailures)}} to enable failFast what's the value to disable it ? 

I think {{failFast(boolean)}} is the best solution to enable/disable the functionnality. Continuing Gunnar's idea we might provide two overloaded methods like :

{code}
final Validator validator = factory.unwrap( HibernateValidatorFactory.class )
    .usingContext()
    .failFast()
       .maxFailures( 5 )
    .getValidator();
{code}

The above method enables failFast and allow to customize it with the max failures value.

{code}
final Validator validator = factory.unwrap( HibernateValidatorFactory.class )
    .usingContext()
    .failFast( false )
    .getValidator();
{code}

The above method could be used to simply enable it (maxFailures(1)) and to disable it. 

WDYT ?
