Subject: Iterate with condition

Hi,

I need but actually don't find how to iterate an iterable collection  
in Java-way. It seems generally like this:

Iterator it = objs.iterator();
while (it.hasMore()) {
     Object anObj = it.next();
     ...
}

How can I do it in Ruby? I know objs.each do |anObj| ... end but it's  
not (enough) good for me. I want to use additional cycle condition  
like this:

boolean b = true;
Iterator it = objs.iterator();
while (b && it.hasMore()) {
     Object anObj = it.next();
     ...
}

What is the equivalent to this in Ruby?
Thanks,

     G�bor
