Solved Adding permissions

How would I add permissions to this class? This is a class that is running off of command executor.

Code:

package commands;

import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.Material;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.command.ConsoleCommandSender;
import org.bukkit.configuration.file.FileConfiguration;
import org.bukkit.entity.Player;
import org.bukkit.event.Listener;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.meta.ItemMeta;

import tangster.vampyr.Vampyr;

public class CommandVampyr
  implements CommandExecutor, Listener
{
  private String swordName;

  public CommandVampyr(Vampyr plugin)
  {
    String color = plugin.getConfig().getString("Vampyr.swordColor");
    try {
      this.swordName = (ChatColor.valueOf(color.toUpperCase()) + plugin.getConfig().getString("Vampyr.swordName"));
    } catch (IllegalArgumentException e) {
      Bukkit.getConsoleSender().sendMessage("[Vampyr] " + color + " is not a valid color in the config file");
    }
  }

  public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args)
  {
    if (!(sender instanceof Player)) {
      sender.sendMessage(ChatColor.RED + "[Vampyr] Player only.");
      return false;
    }

    Player player = (Player)sender;
    if (label.equalsIgnoreCase("vampyr"))
    {
      ItemStack itemInHand = player.getItemInHand();
      ItemMeta meta = itemInHand.getItemMeta();
      if (itemInHand.getType().equals(Material.IRON_SWORD))
      {
        if ((meta.getDisplayName() != null) && (meta.getDisplayName().equals(this.swordName))) {
          player.sendMessage(ChatColor.RED + "[Vampyr] This sword is already a " + this.swordName);
        } else {
          meta.setDisplayName(this.swordName);
          itemInHand.setItemMeta(meta);
        }
      }
      else {
        player.sendMessage(ChatColor.RED + "[Vampyr] Command only works with an Iron Sword");
      }
    }
    return false;
  }
}

 

getServer().getPluginManager().addPermission(new Permission("Perm.perm"));

 

player.hasPermission(string)

 

Disregard what I said, i;m now trying to make it so only OPs can do it. Why is this still not working?

Code:

package commands;

import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.Material;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.command.ConsoleCommandSender;
import org.bukkit.configuration.file.FileConfiguration;
import org.bukkit.entity.Player;
import org.bukkit.event.Listener;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.meta.ItemMeta;

import tangster.vampyr.Vampyr;

public class CommandVampyr
  implements CommandExecutor
{
  private String swordName;

  public CommandVampyr(Vampyr plugin)
  {
    String color = plugin.getConfig().getString("Vampyr.swordColor");
    try {
      this.swordName = (ChatColor.valueOf(color.toUpperCase()) + plugin.getConfig().getString("Vampyr.swordName"));
    } catch (IllegalArgumentException e) {
      Bukkit.getConsoleSender().sendMessage("[Vampyr] " + color + " is not a valid color in the config file");
    }
  }

  public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args)
  {
    if (!(sender instanceof Player)) {
      sender.sendMessage(ChatColor.RED + "[Vampyr] Player only.");
      return false;
    }

    Player player = (Player)sender;
    if (label.equalsIgnoreCase("vampyr"))
    {
        if(sender.isOp()){
      ItemStack itemInHand = player.getItemInHand();
      ItemMeta meta = itemInHand.getItemMeta();
      if (itemInHand.getType().equals(Material.IRON_SWORD))
      {
        if ((meta.getDisplayName() != null) && (meta.getDisplayName().equals(this.swordName))) {
          player.sendMessage(ChatColor.RED + "[Vampyr] This sword is already a " + this.swordName);
        } else {
          meta.setDisplayName(this.swordName);
          itemInHand.setItemMeta(meta);
        }
      }
      else {
        player.sendMessage(ChatColor.RED + "[Vampyr] Command only works with an Iron Sword");
      }
    }
    }
 
    return false;
}
}

Nevermind, I've fixed it.
