easy-events is a simple Java event library which features a minimal and compact design.
How do I use it?
For this example we will create a class that defines two events.
public class Server {
private final Event<String> userJoinedEvent = new SimpleEvent<>();
private final Event<String> userLeftEvent = new SimpleEvent<>();
private final List<String> users = new ArrayList<>();
public Event<String> userJoinedEvent() {
return userJoinedEvent;
}
public Event<String> userLeftEvent() {
return userLeftEvent;
}
public void addUser(String user) {
if (users.add(user)) {
userJoinedEvent().trigger(user);
}
}
public void removeUser(String user) {
if (users.remove(user)) {
userLeftEvent().trigger(user);
}
}
}
The following snippet will use this class:
Server server = new Server();
server.userJoinedEvent().addListener(user -> System.out.println("User joined: " + user));
server.userLeftEvent().addListener(user -> System.out.println("User left: " + user));
server.addUser("Bob");
server.addUser("Jack");
server.addUser("Philipp");
server.addUser("John");
server.removeUser("Bob");
server.removeUser("John");
If we execute the above snippet the following output should appear in the console:
User joined: Bob
User joined: Jack
User joined: Philipp
User joined: John
User left: Bob
User left: John
How do I get it?
You can obtain pre-built JARs in the Releases tab or clone the repository and compile it yourself.
Alternatively you can add it as a Maven dependency. Note: The Maven dependency is a 'fake' dependency which uses JitPack to fetch the git repository and use it. Because of this you have to add a custom repository to your POM.
<dependencies>
<dependency>
<groupId>com.github.Fylipp</groupId>
<artifactId>easy-events</artifactId>
<version>v1.1.0</version>
</dependency>
</dependencies>
<repositories>
<repository>
