kotlin.collections.AbstractIterator

<init>

AbstractIterator()

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-

computeNext

abstract fun computeNext()

Computes the next item in the iterator.

done

fun done()

Sets the state to done so that the iteration terminates.

hasNext

open fun hasNext(): Boolean

Returns true if the iteration has more elements.

next

open fun next(): T

Returns the next element in the iteration.

setNext

fun setNext(value: T)

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

asSequence

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.

forEach

fun <T> Iterator<T>.forEach(operation: (T) -> Unit)

Performs the given operation on each element of this Iterator.

iterator

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.

withIndex

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

Returns an Iterator wrapping each value produced by this Iterator with the IndexedValue, containing value and it's index.
