Class EventBusHook

java.lang.Object

net.kuujo.vertigo.hook.EventBusHook

All Implemented Interfaces:

ComponentHook, Hook, InputHook, IOHook, OutputHook, JsonSerializable

public class EventBusHook
extends Object
implements ComponentHook

Event bus based hook implementation.

This hook publishes events to the event bus. Messages are published to the given address. If no address is provided then messages will be published to the internal address of the component to which the hook is attached.

Messages are formatted as JsonObject instances. Each message will have an event key which indicates the event that occurred. Additional keys depend on the event.

You can use an EventBusHookListener to listen for messages from an EventBusHook. This listener will handle parsing messages and calling event handlers.
