Save the world? - Help!

I'm trying to figure out to save world information. I'm able to get player info to save, but not the world.

I see this:

save() - Method in interface org.bukkit.World
Saves world to disk
SaveCommand - Class in org.bukkit.command.defaults
SaveCommand() - Constructor for class org.bukkit.command.defaults.SaveCommand

But I'm not sure how to use it? I mean I could always use the source for SaveCommand, but I'm sure there is a better way? Maybe?

Code:

                            for (World world : Bukkit.getWorlds())
                            {world.save();}

 

Why do you think it's a bad way?
It's a perfect way to do that:
you iterate through all loaded worlds and save them.

 

I guess what I am getting at, I don't understand how to use the save's in the docs versus copy/paste the code it runs.

 

..what?
