Kamil Domański commented on MESOS-1778:
---------------------------------------
[~alex-mesos], I see a lot of value checks after each call to Flags::load( ).
> Provide an option to validate flag value in stout/flags.

> URL: https://issues.apache.org/jira/browse/MESOS-1778
> Project: Mesos
> Issue Type: Improvement
> Components: stout
> Reporter: Alexander Rukletsov
> Priority: Minor
>
> Currently we can provide the default value for a flag, but cannot check if
> the flag is set to a reasonable value and, e.g., issue a warning. Passing an
> optional lambda checker to {{FlagBase::add()}} can be a possible solution.
