Package org.apache.poi.util

Class IntMapper<T>

  • All Implemented Interfaces:
    java.lang.Iterable<T>, org.apache.poi.common.Duplicatable
    public class IntMapper<T>
extends java.lang.Object
implements org.apache.poi.common.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
