Listening for option changes

Monitoring changes to options for any reason is simple, thanks to the convenient methods provided by OneConfig. You can use them like so:

Java

public MyConfig() {
    addCallback("myOptionName", () -> {
        System.out.println("myOptionName changed!");
    });
}

Kotlin

init {
    addCallback("myOptionName") {
        println("myOptionName changed!");
    }
}

Easy enough, eh? But what if we want to know the new value at the time of the change?

Java

public MyConfig() {
    addCallback<Boolean>("myOptionName", (value) -> {
        System.out.println("myOptionName value: " + value);
    });
}

Kotlin

init {
    addCallback<Boolean>("myOptionName") { value ->
        println("myOptionName value: $value")
    }
}
