interface MutableListIterator<T> : 
    ListIterator<T>,
    MutableIterator<T>

An iterator over a mutable collection that supports indexed access. Provides the ability to add, modify and remove elements while iterating.

Functions

add

Adds the specified element element into the underlying collection immediately before the element that would be returned by next, if any, and after the element that would be returned by previous, if any. (If the collection contains no elements, the new element becomes the sole element in the collection.) The new element is inserted before the implicit cursor: a subsequent call to next would be unaffected, and a subsequent call to previous would return the new element. (This call increases by one the value that would be returned by a call to nextIndex or previousIndex.)

asSequence

iterator

Returns the given iterator itself. This allows to use an instance of iterator in a for loop.

withIndex

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

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