# KEventBus
JVM Eventbus focused on thread-safety and performance.
## Registering
**Kotlin**
```kotlin
// Create eventbus
private val eventBus = eventbus {
invoker { LMFInvoker() }
exceptionHandler { exception -> println("Error occurred in method: ${exception.message}") }
}
// Method you would like to subscribe to an event
// Param #1 is MessagedReceivedEvent therefore this method will be subscribed to that class
@Subscribe
fun `subscribed method`(event: MessageReceivedEvent) {
// do something
println(event.message)
}
...
// Register all the @Subscribe 'd methods inside of an instance
eventBus.register(this)
```
**Java**
```java
// Create eventbus
private EventBus eventBus = new EventBus(new LMFInvoker(), e -> {
System.out.println("Error occurred in method: " + e.getMessage());
});
// Method you would like to subscribe to an event
// Param #1 is MessagedReceivedEvent therefore this method will be subscribed to that class
@Subscribe
public void subscribedMethod(MessageReceivedEvent event) {
System.out.println(event.getMessage());
}
...
// Register all the @Subscribe 'd methods inside of an instance
eventBus.register(this)
```
## Posting
**Kotlin**
```kotlin
// Post all methods subscribed to the event `MessageReceivedEvent`
eventBus.post(MessageReceivedEvent("Hello world"))
```
**Java**
```java
// Post all methods subscribed to the event `MessageReceivedEvent`
eventBus.post(new MessageReceivedEvent("Hello world"));
```
## Unregistering
**Kotlin**
```kotlin
// Remove all @Subscribe 'd methods from an instance
eventBus.unregister(this)
```
**Java**
```java
// Remove all @Subscribe 'd methods from an instance
eventBus.unregister(this)
```
