Extension Functions

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.
