Additional Functionality Example for exe 4

// Example use of our executable message in a simple workflow
FixedSender<Message<Integer, ExecutableBody<String, String>>> messageSender = new FixedSender<>(
        new Message<>(0, new ExecutableBody<>(m -> {
                System.out.println(m);
                sender.start();
            }, "this is the body")));
new ExecutingReceiver<>(messageSender.getOutput(), "Hello, World!");
messageSender.start();

Getting Started

Simple example of our workflow framework using Doubles.

FixedSender<Double> sender = new FixedSender<>(2.00, 3.00, 4.00, -3.5);
Multiplier times2 = new Multiplier(sender.getOutput(),2);
new PrintReceiver<>(times2.getOutput());
sender.start();

//output
4.0
6.0
8.0
-7.0

Workflow nodes for other types can easily be implemented. For instance:

public class Reverser extends Transformer<String> {

    public Reverser(Output<String> input){
        super(input);
    }

    @Override
    protected String transform(String value) {
        return new StringBuilder(value).reverse().toString();
    }
}

More elaborate example can be found in main

Prerequisites

Caution

This framework is mostly barebones at the moment so dont expect too much functionality.
