AbstractIterator

Platform and version requirements: JVM (1.0), JS (1.0), Native (1.0)
abstract class AbstractIterator<T> : Iterator<T>

A base class to simplify implementing iterators so that implementations only have to implement computeNext to implement the iterator, calling done when the iteration is complete.

Constructors

Platform and version requirements: JVM (1.0), JS (1.0), Native (1.0)

<init>

A base class to simplify implementing iterators so that implementations only have to implement computeNext to implement the iterator, calling done when the iteration is complete.

Functions

Platform and version requirements: JVM (1.0), JS (1.0), Native (1.0)

computeNext

Computes the next item in the iterator.

abstract fun computeNext()
Platform and version requirements: JVM (1.0), JS (1.0), Native (1.0)

done

Sets the state to done so that the iteration terminates.

fun done()
Platform and version requirements: JVM (1.0), JS (1.0), Native (1.0)

hasNext

open fun hasNext(): Boolean
Platform and version requirements: JVM (1.0), JS (1.0), Native (1.0)

next

open fun next(): T
Platform and version requirements: JVM (1.0), JS (1.0), Native (1.0)

setNext

Sets the next value in the iteration, called from the computeNext function

fun setNext(value: T)

Extension Functions

Platform and version requirements: JVM (1.0), JS (1.0), Native (1.0)

asSequence

Creates a sequence that returns all elements from this iterator. The sequence is constrained to be iterated only once.

fun <T> Iterator<T>.asSequence(): Sequence<T>
Platform and version requirements: JVM (1.0), JS (1.0), Native (1.0)

forEach

Performs the given operation on each element of this Iterator.

fun <T> Iterator<T>.forEach(operation: (T) -> Unit)
Platform and version requirements: JVM (1.0), JS (1.0), Native (1.0)

iterator

Returns the given iterator itself. This allows to use an instance of iterator in a for loop.

operator fun <T> Iterator<T>.iterator(): Iterator<T>
Platform and version requirements: JVM (1.0), JS (1.0), Native (1.0)

withIndex

Returns an Iterator that wraps each element produced by the original iterator into an IndexedValue containing the index of that element and the element itself.

fun <T> Iterator<T>.withIndex(): Iterator<IndexedValue<T>>
