BELUGA BEHR commented on COLLECTIONS-667:
-----------------------------------------
Something akin to
[IteratorUtils|https://commons.apache.org/proper/commons-collections/javadocs/api-release/org/apache/commons/collections4/IteratorUtils.html#chainedIterator(java.util.Iterator...)].
{code}
public Collection concat(Collection c...) {
ArrayList results = new ArrayList():
for (Collection a : c) {
results.addAll(a);
}
return results;
{code}
* May want to size the ArrayList first to avoid having to expand the internal
buffer multiple times
* Maybe create a new Collection object that keeps a pointer to each internal
Collection
