Method Detail

apply

public int[] apply(long index)

Specified by:

apply in interface java.util.function.LongFunction<int[]>

split

public Splittable.LongIndexed<int[]> split()

Description copied from interface: Splittable

Splits this instance.

Specified by:

split in interface Splittable<Splittable.LongIndexed<int[]>>

Returns:

a Splittable. This is usually a newly created instance, but may also be this instance, if the implementing class has no state.

unrank

public int[] unrank()

Specified by:

unrank in interface IntArraySupplier

Returns:

the next value to be supplied. It is assumed that the next value cannot be obtained using the current one, but it has to be computed based on an index (or some similar information) handled by the implementing class.
