Trait AnyStepper.AnyStepper

trait AnyStepper[+A] extends Stepper[A]

A Stepper for arbitrary element types. See Stepper.

Abstract methods

Source

def trySplit(): AnyStepper[A]

Split this stepper, if applicable. The elements of the current Stepper are split up between the resulting Stepper and the current stepper.

May return null, in which case the current Stepper yields the same elements as before.

See method trySplit in java.util.Spliterator.

Concrete methods

Source

def javaIterator[B >: A]: Iterator[B]

Returns a Java java.util.Iterator corresponding to this Stepper.

Note that the return type is Iterator[_] instead of Iterator[A] to allow returning a java.util.PrimitiveIterator.OfInt (which is a Iterator[Integer]) in the subclass IntStepper (which is a Stepper[Int]).

Source

def spliterator[B >: A]: Spliterator[B]

Returns a java.util.Spliterator corresponding to this Stepper.

Note that the return type is Spliterator[_] instead of Spliterator[A] to allow returning a java.util.Spliterator.OfInt (which is a Spliterator[Integer]) in the subclass IntStepper (which is a Stepper[Int]).

Inherited methods

Source

def characteristics: Int

Returns a set of characteristics of this Stepper and its elements. See method characteristics in java.util.Spliterator.

Source

def estimateSize: Long

Returns an estimate of the number of elements of this Stepper, or Long.MaxValue. See method estimateSize in java.util.Spliterator.

Source

def hasStep: Boolean

Check if there's an element available.

Source

def iterator: Iterator[A]

Returns an Iterator corresponding to this Stepper. Note that Iterators corresponding to primitive Steppers box the elements.

Source

def nextStep(): A

Return the next element and advance the stepper
