Reading / Saving Lists to Config (derp)

Hey guys,

I've been trying to work with lists lately, more specifically writing lists to a custom config file then reading them again later. This is what my config would look like (for example):

Code:

Players:
  Player1:
    items:    
      ID of some item (int)
      ID of another item..and so on
  Player2:
    items:    
      ID of some item(int)
      ID of another item...and so on

So my first question is, when declaring the path to the list "items", would I do

Code:

getConfig().getStringList("Player1.items")

? ​

​

Pretty much I just need some example code on which type of list to do, and how to write and read it from a config file.​

​

Thanks! ​

 

You should be using getConfig().getIntegerList("Players.Player1.items");

 

SnipsRevival Oh, that makes sense. So just to clarify, to write to the list I could use

Code:

getConfig().getIntegerList("Players.Player1.items").add(some integer here);

And that will just add to the list, not override anything.

And if I have multiple players under Player: then would I need to make a StringList of player?

 

You can try doing that, but I don't think it works. The way I have always been adding to lists is by doing

Code:

ArrayList<Integer> list = (ArrayList<Integer>) getConfig().getIntegerList("Players.Player1.items")
 
list.add(your int);
getConfig().set("Players.Player1.items", list);
saveConfig();

This will definitely allow you to set and add to a list without overwriting anything.

 

SnipsRevival Ok, cool. Thanks! One more quick question lol. When I declare the ArrayList, instead of doing Players.Player1 could I just use

Code:

"Players." + player.getName()

so I can actually get their real name? And if that path does not already exist, I am assuming it will be created?

 

Yeah but make sure you also change the path of the list when you use set()

 

SnipsRevival Thanks I'm going to leave the post unsolved until I try this out, just in case

 

To check if the path exists, just use:

if (!(config.contains(path))){
config.set(path, value);
}
get and other code stuff

 

Reteckz Yeah, I figured that out lol. Just curious, how would I check if a value in a list exists? I'm a huge noob when it comes to lists as you can tell, I really don't know why.

 

Googled it :3

Arrays.asList(...).contains(...)

 

That shouldn't be necessary to check if the path already exists because if it doesn't exist, you will just be adding integers to an empty list and then setting that path as the list. If the path already exists, you would just be getting the existing integers and adding the new integer to that and then resetting the path to the new list of integers.
