-/**
- * An interface for getting items, one at a time, from an object.
- *
- * The for-in construct transparently uses Iterator to test for the end
- * of the iteration, and to get each item (or _element_).
- *
- * If the object iterated over is changed during the iteration, the
- * behavior is unspecified.
- *
- * The Iterator is initially positioned before the first element. Before
- * accessing the first element the iterator must thus be advanced ([moveNext])
- * to point to the first element. If no element is left, then [moveNext]
- * returns false.
- *
- * A typical usage of an Iterator looks as follows:
- *
- *     var it = obj.iterator;
- *     while (it.moveNext()) {
- *       use(it.current);
- *     }
- *
- * **See also:** [Iteration]
- * (http://www.dartlang.org/docs/dart-up-and-running/contents/ch03.html#ch03-iteration)
- * in the [library tour]
- * (http://www.dartlang.org/docs/dart-up-and-running/contents/ch03.html)

-abstract class Iterator<E> {
-  /**
-   * Moves to the next element. Returns true if [current] contains the next
-   * element. Returns false, if no element was left.
-   *
-   * It is safe to invoke [moveNext] even when the iterator is already
-   * positioned after the last element. In this case [moveNext] has no effect.
