-/**
- * This extension of AspectAdapter provides ListChange support.
- * This allows us to convert a set of one or more collections into
- * a single collection, LIST_VALUES.
- * 
- * The typical subclass will override the following methods:
- * #listIterator_()
- *     at the very minimum, override this method to return a list iterator
- *     on the subject's list aspect; it does not need to be overridden if
- *     #listIterator() is overridden and its behavior changed
- * #get(int)
- *     override this method to improve performance
- * #size_()
- *     override this method to improve performance; it does not need to be overridden if
- *     #size() is overridden and its behavior changed
- * #listIterator()
- *     override this method only if returning an empty list iterator when the
- *     subject is null is unacceptable
- * #size()
- *     override this method only if returning a zero when the
- *     subject is null is unacceptable
