No import is needed.

Iterator

Pull one element at a time. Concrete iterators (ListIterator, …) implement this. @next lives on the implementing class (attributes are not required on the interface).

public interface Iterator<T>

next

Returns the next value, or None when the sequence has ended.

unique fun next(): Option<T>

close

Ends iteration and releases resources held by the cursor.

unique fun close(): void
