Extensions to Primitive Arrays

The class de.fhg.fokus.xtensions.iteration.PrimitiveArrayExtensions contains extension methods for arrays of primitive values (int, long, double) to iterate with a forEach method consuming primitive values.

Example:

import static extension de.fhg.fokus.xtensions.iteration.PrimitiveArrayExtensions.*
// ...
val int[] arr = #[3,4,6]
arr.forEachInt [
	println(it)
]

Additionally the class allows to create primitive iterable wrapper objects (see Primitive Iterables).

Tip	The JDK class java.util.Arrays already contains static stream methods that can be used as extension methods to create Java 8 streams from primitive arrays.
