General purpose event system

Simple system supporting multiple listeners per class

Usage

Creating an event

import app.sagen.event.*;

public class MyFancyEvent implements Event, Cancelable {
    private static boolean cancelled = false;
    private static MyClass someVariable;
    
    public MyFancyEvent(MyClass someVariable) {
        this.someVariable = someVariable;
    }
    
    public MyClass getSomeObject() {
        return someObject;
    }
    
    public void changeSomeObject(MyClass someNewVariable) {
        this.someVariable = someNewVariable;
    }
    
    public void setCancelled(boolean cancelled) {
        this.cancelled = cancelled;
    }
    
    public boolean isCancelled() {
        return cancelled;
    }
}

Creating a listener

import app.sagen.event.*;

public class MyListener implements Listener {
    
    @EventHandler(priorty = EventPriority.NORMAL, ignoreCancelled = true)
    public void onMyFancyEvent(MyFancyEvent event) {
        // handle the event and cancel event if fitting.
    }
    
}

Registering the listener

EventDispatcher dispatcher = new EventDispatcher();
dispatcher.registerListener(new MyListener());
