public interface CharContainer extends Iterable<CharCursor> {
Returns an iterator to a cursor traversing the collection. The order of
traversal is not defined. More than one cursor may be active at a time. The
behavior of iterators is undefined if structural changes are made to the
underlying collection.
The iterator is implemented as a cursor and it returns the same cursor
instance on every call to Iterator.next()
(to avoid boxing of primitive types). To read the current list's value (or index in the list) use the cursor's public fields. An example is shown below.
for (CharCursor<char> c : container) {
System.out.println("index=" + c.index + " value=" + c.value);
