import static extension de.fhg.fokus.xtensions.range.RangeExtensions.*

val range = (0..20).withStep(2)
range.stream.filter[it % 5 == 0].sumExtensions to IntegerRange
IntegerRange is a handy type from the Xtend standard library which can
be constructed using the .. operator. But the only way to iterate
over the elements of the range is by boxing the integers while iterating.
The extensions provided by this library allow iterating over the primitive values of the range.
One way to iterate over the range is to use Java 8 streams, by using the
stream or parallelStream extension method from the class
de.fhg.fokus.xtensions.range.RangeExtensions.
Exmaple:
Another way to iterate over the elements of a range is to use the forEachInt method.
Example:
import static extension de.fhg.fokus.xtensions.range.RangeExtensions.*
// ...
val range = (0..20).withStep(2)
range.forEachInt [
println(it)
]To interact with consumers expecting an IntIterable (see Primitive Iterables), which is a generic interface
for iteration over primitive int values provided by this library, the extension method
asIntIterable was provided.
