Method Details

tryAdvance

public boolean tryAdvance(Consumer<? super T> action)

Specified by:

tryAdvance in interface Spliterator<T>

tryAdvanceOrTail

public Spliterator<T> tryAdvanceOrTail(Consumer<? super T> action)

Description copied from interface: Internals.TailSpliterator

Either advances by one element feeding it to consumer and returns this or returns tail spliterator (this spliterator becomes invalid and tail must be used instead) or returns null if traversal finished.

Specified by:

tryAdvanceOrTail in interface Internals.TailSpliterator<T>

Parameters:

action - to feed the next element into

Returns:

tail spliterator, this or null

forEachRemaining

Specified by:

forEachRemaining in interface Spliterator<T>

forEachOrTail

public Spliterator<T> forEachOrTail(Consumer<? super T> action)

Description copied from interface: Internals.TailSpliterator

Traverses this spliterator and returns null if traversal is completed or tail spliterator if it must be used for further traversal.

Specified by:

forEachOrTail in interface Internals.TailSpliterator<T>

Parameters:

action - to feed the elements into

Returns:

tail spliterator or null (never returns this)
