Why can't @FunctionalInterface be applied to a SAM abstract base class

Question

I\'m just starting to learn Camel and the first thing I see is

    context.addRoutes(new RouteBuilder() {
        public void configure() {
            from(         


        

Answer 1

In addition to other wonderful answers it should be mentioned that if you really need to create such RouteBuilder objects very often, you can create a helper method like this:

public static RouteBuilder fromConfigurator(Consumer configurator) {
    return new RouteBuilder() {
        public void configure() {
            configurator.accept(this);
        }
    }
}

And use it like this:

context.addRoutes(fromConfigurator(
    rb->rb.from("file:data/inbox?noop=true").to("file:data/outbox")));
