Gary D. Gregory updated LANG-1495:
----------------------------------
Summary: Add EnumUtils getEnum() methods with default values (was: Add
Overloading Methods To EnumUtils)
> Add EnumUtils getEnum() methods with default values
> ---------------------------------------------------
>
> Key: LANG-1495
> URL: https://issues.apache.org/jira/browse/LANG-1495
> Project: Commons Lang
> Issue Type: Improvement
> Reporter: Cheong Voon Leong
> Priority: Trivial
> Time Spent: 1h 20m
> Remaining Estimate: 0h
>
> I would like to add 2 overloading methods to EnumUtils, getEnum and
> getEnumIgnoreCase.
> Instead of returning null, if not found. In my opinion I think allowing user
> to set a default result is a better approach or return an Optional.
