Get UserMap in Essentials

Did you ever find out how to get that UserMap?

Yes....? Anyway, if anyone knows how to get Essential's instance of IEssentials (named ess), please tell me. I'm currently looking through their code to try to figure it out.

Edit: I can't really do anything kit-wise without getting that variable called "ess."

 

This is a YEAR OLD thread, start a new one instead of necrobumping an old thread.

Besides that, it depends on what you need it for.

I need it to give a kit.


final List<String> items = Kit.getItems(ess, customKits.getUser(p.getName()), args[1], ess.getSettings().getKit(args[1]));

This is not possible due to the fact that I can't get that variable "ess," which is because it does not have any getter, only a setter. It's set when Essentials first loads - https://github.com/essentials/Essen...s/src/com/earth2me/essentials/Essentials.java, and then there's no way (at least that I know of) to get it.

 

Agreed. This was back when I really had little idea what I was doing. Chances are if you're tripping up on this, you may want to watch some tutorials on static references (might I recommend thenewboston).

Uh, no. There's no Essentials.getInstance() or any method like that. I ain't trippin' bro.

 

Because I might as well:
You'll want to use

Code:java

Bukkit.getPluginLoader().getPlugin("Essentials")

. This will give you either null, or the main Essentials instance as a JavaPlugin. Make sure you check it's actually an instanceof Essentials, and it's not null. This will give you access to the Essentials base plugin class, from which you should have access to most things.

 

ZephireNZ
Yes, yes. I've done this and casted Essentials, but my problem is that there's no way to GET that IEssentials variable that's already set. It would be simple if they had a getEss() method, but they don't, and so that's my problem.

 

Hm, in that case I'd take it up with them. You'll likely get a quicker answer that way. Try talking to them on IRC (irc.esper.net, #essentials).

 

ZephireNZ
Yeah I probably have to do that.

 

Lactem
You would actually cast that to IEssentials, the class implements that.

Edit: Whoops, don't do that uet.

Edit:

PHP:

JavaPlugin plugin = Bukkit.getServer().getPluginManager().getPlugin("Essentials");
Class<?> classInstance = plugin.getClassLoader().findClass("com.earth2me.essentials.Essentials");
Class<?> iEssentialsInstance = classInstance.asSubclass(IEssentials.class);
IEssentials ess = (IEssentials) iEssentialsInstance.newInstance();

Edit:

PHP:

JavaPlugin plugin = Bukkit.getServer().getPluginManager().getPlugin("Essentials");
JavaPluginLoader loader = (JavaPluginLoader) plugin.getPluginLoader();

Field f = loader.getClass().getDeclaredField("loaders");
f.setAccessible(true);
Map<String, PluginClassLoader> map = (Map) f.get(loader);

PluginClassLoader load = map.get("Essentials");
Field fd = load.getClass().getDeclaredField("classes");
fd.setAccessible(true);
Map<String, Class<?>> clses = (Map) fd.get(load);

Class<?> finalClass;
for(Class<?> c : clses.valueSet()) {
    if(c.getSimpleName().equals("Essentials")) {
        finalClass = c.asSubclass(IEssentials.class);
    }
}

IEssentials ess = finalClass.newInstance();

 

xTrollxDudex Why use reflection if it can be done much easier? Here is some code directly copied from EssentialsChat:

Code:

final PluginManager pluginManager = getServer().getPluginManager();
final IEssentials ess = (IEssentials)pluginManager.getPlugin("Essentials");
 
if (!ess.isEnabled())
{
    this.setEnabled(false);
    return;
}

Congrats on DBO staff!

Anyways, I was thinking that getPlugin returns the generic plugin "object of the plugin" if you know what I'm saying:

Then again, I always make sure to doubt my own answer.

 

xTrollxDudex Thank you very much
About the "Object of the plugin", indeed, it stores the plugin object.

 

CaptainBern
What about the class reference?

 

xTrollxDudex Why would you need that if casting to IEssentials works perfect?

Edit: You can perfectly cast the Plugin object to IEssentials, add this code to a plugin:

Code:java

System.out.print(Bukkit.getPluginManager().getPlugin("Essentials").getClass().getName());

The expected output will be: com.earth2me.essentials.Essentials.
I'm sorry I can't really explain it any better :/

 

Maybe this helps to understand .....
