iterator

public static PrimitiveIterator.OfDouble iterator (Spliterator.OfDouble spliterator)

Creates an PrimitiveIterator.OfDouble from a Spliterator.OfDouble.

iterator

public static Iterator<T> iterator (Spliterator<? extends T> spliterator)

spliterator

public static Spliterator<T> spliterator (Iterator<? extends T> iterator, 
                long size, 
                int characteristics)

Creates a Spliterator using a given Iterator as the source of elements, and with a given initially reported size.

The spliterator is not late-binding, inherits the fail-fast properties of the iterator, and implements trySplit to permit limited parallelism.

Traversal of elements should be accomplished through the spliterator. The behaviour of splitting and traversal is undefined if the iterator is operated on after the spliterator is returned, or the initially reported size is not equal to the actual number of elements in the source.

spliterator

public static Spliterator.OfLong spliterator (long[] array, 
                int additionalCharacteristics)

Creates a Spliterator.OfLong covering the elements of a given array, using a customized set of spliterator characteristics.

This method is provided as an implementation convenience for Spliterators which store portions of their elements in arrays, and need fine control over Spliterator characteristics. Most other situations in which a Spliterator for an array is needed should use Arrays#spliterator(long[]).

The returned spliterator always reports the characteristics SIZED and SUBSIZED. The caller may provide additional characteristics for the spliterator to report; it is common to additionally specify IMMUTABLE and ORDERED.
