Solved Serialization of a class

Hi everyone!

I have another problem/question.
I wanted to store the whole info of a class via serialization in a config file.
I looked on this wiki page but i didn't understand it that well.

I want searching further (Google & YouTube) but I could not find any tutorials so now I'm asking people the bukkit forum.

How does serialization work and how do I use it?

 

Yeah, that link is quite confusing.

I'll give you an example of how serializing an Arena should work:

Code:

public class Arena implements ConfigurationSerializable {
    private int arenaID = -1;
    private boolean isEnabled = false;
 
    public Arena(int arenaID) {
        this(arenaID, true);
    }
 
    public Arena(int arenaID, boolean enabled) {
        this.arenaID = arenaID;
        this.isEnabled = enabled;
    }
 
    public int getID() {
        return this.arenaID;
    }
 
    public boolean isEnabled() {
        return this.isEnabled;
    }
 
    @Override
    public Map<String, Object> serialize() {
        Map<String, Object> serializedArena = new HashMap<String, Object>();
        serializedArena.put("ID", this.arenaID);
        serializedArena.put("Enabled", this.isEnabled);
        return serializedArena;
    }
 
    public static Arena deserialize(Map<String, Object> serializedArena) {
        int arenaID = serializedArena.get("ID");
        boolean isEnabled = serializedArena.get("Enabled");
        return new Arena(arenaID, isEnabled);
    }
}

Example of saving lots of data: https://github.com/KingFaris10/KingKits/blob/master/src/me/faris/kingkits/Kit.java#L199

I'm not actually sure if you have to register it like: ConfigurationSerialization.registerClass(Arena.class);

I've never done this and I don't see the point of it, until I view the ConfigurationSerialization code.

Look at my edited message, I don't think you need to do that. However, this is how you use it.

So continuing from my example of an Arena, to save it in a config like this:

Code:

Arenas:
    Arena1:
        ID: 1
        Enabled: true

You would do something like this:

Code:

config.set("Arenas.Arena" + arena.getID(), arena.serialize());

Then to load it, you would do something like this:

Code:

Arena arena = Arena.deserialize(config.getConfigurationSection("Arenas.Arena" + arena.getID()).getValues(false));

Thanks!

 

No problem, by the way, I just looked at the code for ConfigurationSerialization, it looks like you should register it anyway. In your onEnable(), using my example of an Arena again, do this:

Code:

ConfigurationSerialization.registerClass(Arena.class);

 

KingFaris11 you are extending an interface

 

Oops, I meant implements.

 

What does it do?

 

No idea, but you just should.

 

HeroWorkbrine KingFaris11 It tells Bukkit (and in turn SnakeYAML) what a certain set of key-value pairs (the Map<String, Object> serialize() returns) belongs to.

 

Thanks for the info!
