top15 richest player with vault

Hello i need made top15 richest player in tab
Tab is done but i must make LinkedHashMap with the richest player
but i don't know how;/
vault have connection with mysql?

 

vault is merely a bridging program to the economy plugins, it is the responsibility of the economy plugin to take care of storing the data, so vault is not mysql linked, but the economy plugin would be.

 

I really don't know if this can works but you can try to do this:

Code:java

 
//On player join event
 
//Save player uuid in yml file or create a yml file with his uuid
 
//Get all uuids
 
//Get offlineplayer with the uuids
 
//Get offlineplayer money
 
//Use a map to make the top
 

 

who to get all uuids when i have config:

Code:

-uuid1
-uuid2
-uuid3

and how i get this uuid to map/list?

I don't know what MaTaMoR_ is really suggesting, his seems too over complicated. It is similar though, just does not need storing UUIDs... From what I think you want, you want to get the top 15 richest players on the server which uses Vault.

I'm pretty sure you could easily do this, though if it is a big server (in terms of number of past players), this may be resource intensive:

Code:

Map<String, Integer> playerBalances = new HashMap<String, Integer>();
for (Player onlinePlayer : Bukkit.getOnlinePlayers()) {
    if (vaultEconomy.hasAccount(onlinePlayer)) playerBalances.put(onlinePlayer.getName(), vaultEconomy.getBalance(onlinePlayer));
}
for (OfflinePlayer offlinePlayer : Bukkit.getOfflinePlayers()) {
    if (offlinePlayer != null && offlinePlayer.getName() != null) { // I have a habit of checking for nulls, you don't need this I think.
        if (vaultEconomy.hasAccount(offlinePlayer)) playerBalances.put(offlinePlayer.getName(), vaultEconomy.getBalance(offlinePlayer));
    }
}
// Sort playerBalances from largest to smallest - look up on how to do this. Then get the top 15 in the list, drpk gave a link.

Sorting from largest to smallest: https://gist.github.com/aadnk/9632795

Example:

Code:

MapSorting.sortedValues(playerBalances);

 

@dekrosik Java has a built-in sort function from the class Collections.
You can use it with: 'Collections.sort(<arraylist or something>)'

 

How about instead of using runtime overhead, we cause more overhead upon insertion but much faster retrieval? There's Queues in the JCF (I'm looking at your PriorityQueue). Use a comparator to assign the wealthiest player a higher priority than the compared players.
