More Config Help -- Arbitrary number of entries

I'm working on a border plugin that supports individual configs for individual worlds, but I am not exactly sure how to create the code to read/write it.

Here is an example the yaml I want:

Code:

worlds:
  world1name:
    x: 0
    z: 0
    radius: 100
  world2name:
    x: 0
    z: 0
    radius: 200
(etc etc for as many worlds being used)
globalconfig1: true
globalconfig2: false

I think the code I need to read it is something like this, but I don't know if it is the best way to go about this, or if it will even work at all. Thanks for any pointers

Code:

HashMap<String, HashMap> worlddb = new HashMap<String, HashMap>();       
        Map<String, ConfigurationNode> worlds = _config.getNodes("worlds");
        Set<String> keys = worlds.keySet();
        Iterator<String> a = keys.iterator();
        for(i=0; i<worlds.size(); i++){    
            String name = a.next();
            int x = worlds.get(name).getInt("x", 0);
            int z = worlds.get(name).getInt("z", 0);
            int r = worlds.get(name).getInt("radius", 0);
            HashMap<String, Integer> world = new HashMap<String, Integer>();
            world.put("x", x);
            world.put("z", z);
            world.put("radius", r);
            worlddb.put(name, world);
        }

 

Have you tried using an entry set instead of keyset?
for (Map.Entry<String, ConfigurationNode> entry : worlds.entrySet()) {
String name = entry.getKey();
int x = worlds.get(name).getInt("x", 0);
int z = worlds.get(name).getInt("z", 0);
int r = worlds.get(name).getInt("radius", 0);
HashMap<String, Integer> world = new HashMap<String, Integer>();
world.put("x", x);
world.put("z", z);
world.put("radius", r);
worlddb.put(name, world);

}

 

That worked, thank you
