E - The type stored in the collection.@CodeReview(reviewer="Kevin R. Dixon", date="2008-02-08", changesNeeded=false, comments={"I\'m impressed: iteration (foreach) works on this class. I was ready to flunk this code review, but my unit test passes.","Looks fine."}) public class RangeExcludedArrayList<E> extends java.util.AbstractList<E> implements java.util.RandomAccess, MultiCollection<E>
RangeExcludedArrayList class implements a light-weight list on
top of an ArrayList where a certain range of values is excluded from
the list. In some ways, this class is a mirror of the subList method that
exists on the ArrayList class, which is that it gives a list that
contains everything, except what is in the sub-list. The implementation
creates a read-only collection that remains O(1) for random access.
Note: One difference from the subList method is that the both indices given
to this list are inclusive, because it makes more sense when excluding a
range.| Constructor and Description |
