fun <T> Iterator<T>.asSequence(): Sequence<T>
fun <T> Iterator<T>.asSequence(): Sequence<T>
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 1.2

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

Performs the given operation on each element of this Iterator.

Since Kotlin 1.2
Link copied to clipboard
inline operator fun <T> Iterator<T>.iterator(): Iterator<T>
inline operator fun <T> Iterator<T>.iterator(): Iterator<T>
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 1.2

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