Creates a `Spliterator.OfLong` using a given `LongStream.LongIterator` as the source of elements, with no initial size estimate. 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. Parameters: `iterator` - The iterator for the source `characteristics` - Characteristics of this spliterator's source or elements (`SIZED` and `SUBSIZED`, if supplied, are ignored and are not reported.) Returns: A spliterator from an iterator Throws: `NullPointerException` - if the given iterator is `null`

                                                     int characteristics)
Creates a `Spliterator.OfDouble` using a given `DoubleStream.DoubleIterator` 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. Parameters: `iterator` - The iterator for the source `size` - The number of elements in the source, to be reported as initial `estimateSize` `characteristics` - Characteristics of this spliterator's source or elements. The characteristics `SIZED` and `SUBSIZED` are additionally reported unless `CONCURRENT` is supplied. Returns: A spliterator from an iterator Throws: `NullPointerException` - if the given iterator is `null`
