# VRadio

A thread-safe implementation of the publish-subscribe pattern.

## Jar Files & Maven

To use this project as a Maven dependency, click on the JitPack badge [![Release](https://jitpack.io/v/Valkryst/VRadio.svg)](https://jitpack.io/#Valkryst/VRadio), select a version, click the "Get it!" button, and then follow the instructions.

If you would rather use a Jar file, then you can find the Jars on the [releases](https://github.com/Valkryst/VRadio/releases) page.

## Examples

We'll be using the following Receiver class for all examples.

```java

public class TestReceiver implements Receiver {

    private final String name;

    public TestReceiver(final String name) {

        this.name = name;

    }

    @Override

    public void receive(final String event, final String data) {

        System.out.println(name + " Received:");

        System.out.println("\tEvent:\t" + event);

        System.out.println("\tData:\t" + data);

    }

}

```

---

Construct a Radio and transmit an event with no data to the Receiver.

```java

final TestReceiver receiver = new TestReceiver("ReceiverA");

final Radio radio = new Radio<>();

radio.addReceiver("EventA", receiver);

radio.transmit("EventA");

```

---

Construct a Radio and transmit two different events to three different Receivers.

```java

final TestReceiver receiverA = new TestReceiver("ReceiverA");

final TestReceiver receiverB = new TestReceiver("ReceiverB");

final TestReceiver receiverC = new TestReceiver("ReceiverC");

final Radio radio = new Radio<>();

radio.addReceiver("EventA", receiverA);

radio.addReceiver("EventB", receiverB);

radio.addReceiver("EventA", receiverC);

radio.addReceiver("EventB", receiverC);

System.out.println("Transmitting EventA:");

radio.transmit("EventA", "DataA");

System.out.println("\n\nTransmitting EventB:");

radio.transmit("EventB", "DataB");

```
