NthItem

See javadoc - uk.gov.gchq.koryphe.impl.function.NthItem

Available since Koryphe version 1.1.0

For a given Iterable, an NthItem will extract the item at the Nth index, where n is a user-provided selection. (Consider that this is array-backed, so a selection of "1" will extract the item at index 1, ie the 2nd item)"

Examples

final NthItem<Integer> function = new NthItem<>(2);

{
  "class" : "NthItem",
  "selection" : 2
