Class IntMapper<T>

java.lang.Object

org.apache.poi.util.IntMapper<T>

All Implemented Interfaces:

java.lang.Iterable<T>, Duplicatable

public class IntMapper<T>
extends java.lang.Object
implements Duplicatable, java.lang.Iterable<T>

A List of objects that are indexed AND keyed by an int; also allows for getting the index of a value in the list

I am happy is someone wants to re-implement this without using the internal list and hashmap. If so could you please make sure that you can add elements half way into the list and have the value-key mappings update
