public class FlattenedList

extends java.util.AbstractList

A list of lists that acts as a single list. Note that this only flattens one layer, not completely. For example, if I pass this a list containing two lists, and one list has a list as an element, that list will be returned as a list. Also, it does expect a list of lists.
