Gary D. Gregory commented on LANG-1707:
---------------------------------------
Maybe, but the implementation should allocate a single array, not a temporary
array for each input element.
> Syntactic suger to concatenate arrays
> -------------------------------------
>
> Key: LANG-1707
> URL: https://issues.apache.org/jira/browse/LANG-1707
> Project: Commons Lang
> Issue Type: Wish
> Components: lang.*
> Affects Versions: 3.13.0
> Reporter: Gilles Sadowski
> Priority: Trivial
> Labels: suggestion
> Fix For: 3.14.0
>
>
> In {{ArrayUtils}}, a method such as {{addAll(T[], T ... others)}} makes it
> easy to concatenate two arrays.
> Then, one can concatenate several arrays:
> {code}
> /**
> * @param <T> Type.
> * @param arrays Arrays.
> * @return an array that contains all the elements in the input arrays.
> */
> private static <T> T[] concat(T[] ... arrays) {
> final int numArr = arrays.length;
> T[] concatenated = null;
> for (int i = numArr; i > 0; i--) {
> concatenated = ArrayUtils.addAll(arrays[i - 1], concatenated);
> }
> return concatenated;
> }
> {code}
> Shouldn't {{concat(T[] ...)}} be part of {{ArrayUtils}}?
