Returns true if the iteration has more elements.

abstract operator fun hasNext(): Boolean

Returns the next element in the iteration.

abstract operator fun next(): T

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>

Performs the given operation on each element of this Iterator.

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

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>

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>>

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.

An iterator over a sequence of values of type Boolean.

abstract class BooleanIterator : Iterator<Boolean>

An iterator over a sequence of values of type Byte.
