Solved Unique Players

Hello fellow bukkit developers. This is more of a general question to how bukkit functions rather then a "Heres my code fix it" thread. So, my question is how does bukkit keep track of unique players? Does it keep all the players in a file some where, if so where is the file located? I want to know as a client has asked me to create a plugin which keeps track of unique players (Yes, I know one already exists) but I'm unsure of how bukkit handles unique players.

 

On player join event, you can either give every player their own file, or stick them all into one big file. Check if they already have a file/are in the file, and if not make them one.

Ah, I thought about that but then I realised that bukkit has the "player.isUnique()" method which raised the question. Thanks for the reply.
