Treat Enumeration as Iterator

Question

I have a class that implements the Enumeration interface, but Java\'s foreach loop requires the Iterator interface. Is there an <

Answer 1

a) I'm pretty sure you mean Enumeration, not Enumerator
b) Guava provides a Helper method Iterators.forEnumeration(enumeration) that generates an iterator from an Enumeration, but that won't help you either, as you need an Iterable (a provider of Iterators), not an Iterator
c) you could do it with this helper class:

public class WrappingIterable<E> implements Iterable<E>{
    private Iterator<E> iterator;

    public WrappingIterable(Iterator<E> iterator){
        this.iterator = iterator;
    }

    @Override
    public Iterator<E> iterator(){
        return iterator;
    }
}

And now your client code would look like this:

for(String string : new WrappingIterable<String>(
                        Iterators.forEnumeration(myEnumeration))){
    // your code here            
}

But is that worth the effort?
