-/**
- * This {@link AspectAdapter} provides basic list change support.
- * This converts an "aspect" (as defined by subclasses) into
- * a single {@link #LIST_VALUES} list.
- * <p>
- * The typical subclass will override the following methods:<ul>
- * <li>{@link #engageSubject_()}<p>
- * implement this method to add the appropriate listener to the subject
- * <li>{@link #disengageSubject_()}<p>
- * implement this method to remove the appropriate listener from the subject
- * <li>{@link #listIterator_()}<p>
- * 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
- * {@link #listIterator()} is overridden and its behavior changed
- * <li>{@link #get(int)}<p>
- * override this method to improve performance
- * <li>{@link #size_()}<p>
- * override this method to improve performance; it does not need to be overridden if
- * {@link #size()} is overridden and its behavior changed
- * <li>{@link #toArray_()}<p>
- * override this method to improve performance; it does not need to be overridden if
- * {@link #toArray()} is overridden and its behavior changed
- * <li>{@link #listIterator()}<p>
- * override this method only if returning an empty list iterator when the
- * subject is null is unacceptable
- * <li>{@link #size()}<p>
- * override this method only if returning a zero when the
- * subject is null is unacceptable
- * <li>{@link #toArray()}<p>
- * override this method only if returning an empty array when the
- * subject is null is unacceptable
- * </ul>
- * To notify listeners, subclasses can call {@link #listChanged()}
- * whenever the aspect has changed.
