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>>
