Method Detail

forEachRemaining

void forEachRemaining(java.util.function.Consumer<? super A> c)

Specified by:

forEachRemaining in interface java.util.Iterator<A>

Specified by:

forEachRemaining in interface java.util.Spliterator<A>

hasStep

boolean hasStep()

Description copied from interface: StepperLike

`true` if there are more elements to step through, `false` if not.

Specified by:

hasStep in interface StepperLike<A,AnyStepper<A>>

knownSize

long knownSize()

Description copied from interface: StepperLike

Returns the size of the collection, if known exactly, or `-1` if not.

Specified by:

knownSize in interface StepperLike<A,AnyStepper<A>>

nextStep

A nextStep()

Description copied from interface: StepperLike

The next element traversed by this Stepper. nextStep() throws an exception if no elements exist, so check hasStep immediately prior to calling. Note that tryStep also consumes an element, so the result of hasStep will be invalid after tryStep is called.

Specified by:

nextStep in interface StepperLike<A,AnyStepper<A>>

Returns:

(undocumented)

tryAdvance

boolean tryAdvance(java.util.function.Consumer<? super A> c)

Specified by:

tryAdvance in interface java.util.Spliterator<A>

tryStep

boolean tryStep(scala.Function1<A,scala.runtime.BoxedUnit> f)

Description copied from interface: StepperLike

If another element exists, apply `f` to it and return `true`; otherwise, return `false`.

Specified by:

tryStep in interface StepperLike<A,AnyStepper<A>>

trySplit

AnyStepper<A> trySplit()

Specified by:

trySplit in interface java.util.Spliterator<A>

spliterator

java.util.Spliterator<A> spliterator()

Description copied from interface: StepperLike

Returns this Stepper as a java.util.Spliterator. This is a terminal operation.

Specified by:

spliterator in interface StepperLike<A,AnyStepper<A>>

Returns:

(undocumented)

seqStream

java.util.stream.Stream<A> seqStream()

parStream

java.util.stream.Stream<A> parStream()
