AbstractIterator

abstract class AbstractIterator<T> : Iterator<T> (source)

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.

Since Kotlin

fun <T> Iterator<T>.asSequence(): Sequence<T>

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

Since Kotlin 1.1
fun <T> Iterator<T>.asSequence(): Sequence<T>

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

protected abstract fun computeNext()

Computes the next item in the iterator.

Since Kotlin 1.1
protected abstract fun computeNext()

Computes the next item in the iterator.

protected fun done()

Sets the state to done so that the iteration terminates.

Since Kotlin 1.1

inline operator fun <T> Iterator<T>.iterator(): Iterator<T>

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

Since Kotlin 1.1

open operator override fun next(): T

Returns the next element in the iteration.

Since Kotlin 1.1
open operator override fun next(): T

Returns the next element in the iteration.

protected fun setNext(value: T)

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

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

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.

Since Kotlin 1.1
fun <T> Iterator<T>.withIndex(): Iterator<IndexedValue<T>>

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.
