use object for interative loop

Hi, I have an object that I want to iterate through it's members with a while loop but I can't see how to call the while loop? Thanks, tom

classdef cls_myobj
    properties
       members = {'abc' 'bbc' 'cbc'}
       length = 3
       index = 0
    end
    methods
       function [this,obj] = getNext(this)
          this.index = this.index +1;
          if this.index > this.length
             obj = -1; %or false???
          else
             obj = this.members(this.index);
          end
     end
end

myobj=cls_myobj;
while [this, x] = getNext(myobj)
   %do stuff
end

I guess I can answer this myself now

while myobj.index < myobj.length
   [myobj, newthing] = myobj.getNext(myobj)
   %do thing with newthing
end

It doesn't look right that you have myobj.method and method(myobj). I'd expected you'd only need one or the othr

[myobj,newthing] = getNext(myobj);
