Proposed IterableEnumVariant class.

[EJP286CRSKW]

I propose this addition to the com.jacob.com package. It is an Iterable and Stream-able subclass of EnumVariant.

IteratableEnumVariant class.

package com.jacob.com;

import java.util.Iterator;
import java.util.stream.Stream;
import java.util.stream.StreamSupport;

/**
 * Iterable and streaming EnumVariant.
 * 
 * @author Esmond Pitt
 * @since 1.21
 */
public class IterableEnumVariant extends EnumVariant implements Iterable<Variant>
{
    /**
     * Construct an instance.
     * 
     * @param variant Variant from which to obtain the enumeration.
     */
    public IterableEnumVariant(Variant variant)
    {
        super(variant.m_pVariant);
    }
    
    /**
     * {@inheritDoc}
     * <p>
     * This implementation resets the EnumVariant,
     * so that <code>iterator()</code> can be called multiple times,
     * as can {@link #stream}.
     */
    @Override
    public Iterator<Variant>   iterator()
    {
        super.Reset();
        return new Iterator<Variant>()
        {
            @Override
            public boolean  hasNext()
            {
                return hasMoreElements();
            }
            
            @Override
            public Variant  next()
            {
                return nextElement();
            }
        };
    }
    
    /**
     * Get a Stream from this object.
     * 
     * @return Stream&lt;Variant&gt;.
     */
    public Stream<Variant> stream()
    {
        return StreamSupport.stream(this.spliterator(), false);
    }
}

(or better still fold this into EnumVariant.

Sample code?

[EJP286CRSKW]

Sure. Executing a query:

Stream
    .of(wmiServer)
    .map(w -> w.invoke("ExecQuery", new Variant(query)))
    .map(Variant::toDispatch)
    .map(IterableActiveXComponent::new)
    .flatMap(IterableActiveXComponent::stream)
// .peek(System.out::println)
   .forEach
   (
       a ->
       {
//        System.out.println("query result="+a.getProperty("Name"));
       }
   )
   ;

1. The example uses IterableActiveXComponent which does not exist in the current code base
2. Could you provide the sample query

Added to EnumVariant 75124c9

Still need sample code or the IterableActiveXComponent
