  • Class
    Description
    AnnotatedEventHandler
    Extending this class will allow you to colocate multiple related Event handling methods inside the same class and use it together with the LocalEventBus
    Each method must accept a single Event argument, return void and be annotated with the Handler annotation.
    The method argument type is matched against the concrete event type using Class.isAssignableFrom(Class).
    The method accessibility can be any combination of private, protected, public, etc.
    Example:
    EventBus
    Simple event bus concept that supports both synchronous and asynchronous subscribers that are registered and listening for events published

    Usage example:
    EventHandler
    Common interface for all Event message handlers
    Handler
    Generic Method annotation that can be applied to any single argument method inside a AnnotatedCommandHandler or AnnotatedEventHandler.
    Depending on which class you extend the rules that apply to each method may be different.
    Common for all is that the method accessibility can be any combination of private, protected, public, etc.
    LocalEventBus
    Simple event bus that supports both synchronous and asynchronous subscribers that are registered and listening for events published within the local the JVM
    You can have multiple instances of the LocalEventBus deployed with the local JVM, but usually one event bus is sufficient.

    Example:
    OnErrorHandler
    Error Handler interface for the LocalEventBus's asynchronous event handler failures
