public class LongListAdapter extends java.util.AbstractList implements java.util.List
Adapter that permits anAbstractLongList
to be viewed and treated as a JDK 1.2AbstractList
. Makes the contained list compatible with the JDK 1.2 Collections Framework.Any attempt to pass elements other than java.lang.Number to setter methods will throw a java.lang.ClassCastException. java.lang.Number.longValue() is used to convert objects into primitive values which are then stored in the backing templated list. Getter methods return java.lang.Long objects.
