## com.sun.javatest.util
Class OrderedTwoWayTable

    java.lang.Object
      com.sun.javatest.util.OrderedTwoWayTable

    public class OrderedTwoWayTable

extends java.lang.Object

A map-like structure which has two side-by-side ordered sets of Objects in pairs. This is basically a map structure except that it is always ordered and has a less strict an idea of key and value. The terms key and value are still used to differentiate data from the two sets. The primary advantage to using this class is that you can do lookups either by key or value, in case where translation in both directions is necessary.
