Consequently, a List method + * that modifies data, does not modify InterfaceContainer's data at a certain index + * (according to the iterators cursor).

However, the list iterators returned, for example by + * the listIterator method implement the java.util.ListIterator interface. + * Implementing the List interface would mean to support all none - optional methods as + * prescribed by the interface declaration. Among those is the subList method which returns + * a range of values of the list's data wrapped in a List implementation. Changes to the sub + * list have to cause changes in the main list. This is a problem, since this class is to be + * used in a multi-threaded environment. The sub list could work on a copy as the iterators + * do, but all the functions which work on a given index could not be properly supported. + * Unfortunately, the List interface documentation states that all optional methods implemented + * by the list have to be implemented in the sub list.
