Remarks

Creates a Spliterator over the elements in this collection.

Implementations should document characteristic values reported by the spliterator. Such characteristic values are not required to be reported if the spliterator reports Spliterator#SIZED and this collection contains no elements.

The default implementation should be overridden by subclasses that can return a more efficient spliterator. In order to preserve expected laziness behavior for the #stream() and #parallelStream() methods, spliterators should either have the characteristic of IMMUTABLE or CONCURRENT, or be <em>late-binding</em>. If none of these is practical, the overriding class should describe the spliterator's documented policy of binding and structural interference, and should override the #stream() and #parallelStream() methods to create streams using a Supplier of the spliterator, as in:

{@code
                Stream<E> s = StreamSupport.stream(() -> spliterator(), spliteratorCharacteristics)
            }

These requirements ensure that streams produced by the #stream() and #parallelStream() methods will reflect the contents of the collection as of initiation of the terminal stream operation.
