Stephen Colebourne commented on LANG-238:
-----------------------------------------
This newly defined method seems a little unusual - is it really a generic use
case? How often do you need to test that all elements in an array are the same?
A more general related method might be:
containsOnly(arrayToTest, arrayOfPermittedValues)
> [lang] Add equals(type[]) to NumberUtils

> It would be useful to add an equals() method like the current min and max
> methods which take an array type and determine if all the values are equal.
> I have found myself in need of this often. I have to retrieve objects from
> multiple data sources in parallel to build an array of complex object. To
> ensure
> validity, I always compare that my sub-retrievals returned the same number of
> objects as expected.
