getting players with permission

how would i go about checking all players online then doing something to ones with certain permission nodes. im having trouble figuring this out. if i missed the methods in the api reference link me if not pseudo code would be nice

 

if(player.hasPermission("Permission.*")
{

}

Something like that?

 

obviousely but i need to get all players first im not targeting a player who performed an event or command

 

i see...

is it going to be a broadcast or some code that is ran only on certain players?

not a broadcast sent to one or multiple players that have the permission node

for(Player p : Bukkit.getServer().getOnlinePlayers){
if(p.hasPermission("Permission"){
//Something happens here.
}
}
