Class Numbered<T>

java.lang.Object

org.dmfs.iterables.decorators.DelegatingIterable<Pair<java.lang.Integer,T>>

org.dmfs.jems.iterable.decorators.Numbered<T>

All Implemented Interfaces:

java.lang.Iterable<Pair<java.lang.Integer,T>>

public final class Numbered<T>
extends DelegatingIterable<Pair<java.lang.Integer,T>>

An Iterable decorator which pairs every value of another iterator with it's sequential ordinal number.

Example:

     Iterable<String> strings = new Seq<>("a", "b", "c");
     for (Pair<Integer, String> item:new Numbered<>(strings))
     {
        System.out.println(String.format("%d: %s", item.left(), item.right());
     }
 

results in

 0: a
 1: b
 2: c
