eventemitter

A simple library implementing an event emitter in Java, made to use closures. It's way simpler and shorter than Swing's crappy EventListener.

Installation

See the page on search.maven.org for Gradle of Maven configuration per version.

Usage

// ExampleClass.java
package example;

import eventemitter.EventEmitter;
import lombok.Getter;
import lombok.NonNull;

public class ExampleClass {
    
    @Getter
    private final EventEmitter<String> statusChanged = new EventEmitter<>();
    
    @Getter
    @NonNull
    private String status = "";
    
    public void setStatus(String stat) {
        this.status = stat;
        this.getStatusChanged().trigger(stat);
    }
}

// ExampleConsumer.java
package example;

public class ExampleConsumer {
    public static void main(String[] args) {
        ExampleClass e = new ExampleClass();
        
        e.getStatusChanged().addConsumer((s) -> {
            System.out.println("New status is " + s);
        });
        
        e.setStatus("waiting");
    }
}
