An iterator over a mutable collection that supports indexed access. Provides the ability to add, modify and remove elements while iterating.
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.)
abstract fun add(element: T)
true if the iteration has more elements.
abstract fun hasNext(): Boolean
Returns the next element in the iteration.
abstract fun next(): T
Removes from the underlying collection the last element returned by this iterator.
abstract fun remove()
