public interface IJIEnumVariant
Represents the Windows COM IEnumVARIANT
Interface.
Sample Usage:-
//From MSEnumVariant example
JIVariant variant = dispatch.get("_NewEnum");
IJIComObject object2 = variant.getObjectAsComObject();
IJIEnumVariant enumVARIANT = (IJIEnumVariant)JIObjectFactory.narrowObject(object2.queryInterface(IJIEnumVariant.IID));
for (i = 0; i < 10; i++)
{
Object[] values = enumVARIANT.next(1);
JIArray array = (JIArray)values[0];
Object[] arrayObj = (Object[])array.getArrayInstance();
for (int j = 0; j < arrayObj.length; j++)
{
System.out.println(((JIVariant)arrayObj[j]).getObjectAsInt() + "," + ((Integer)values[1]).intValue());
}
}

There is no guarantee that exactly the same set of variants will be enumerated the second time as was enumerated the first. Although an exact duplicate is desirable, the outcome depends on the collection being enumerated. You may find that it is impractical for some collections to maintain this condition (for example, an enumeration of the files in a directory).
