Class EventHandler<T extends net.dv8tion.jda.api.events.interaction.GenericInteractionCreateEvent>

java.lang.Object

com.github.kaktushose.jda.commands.dispatching.handling.EventHandler<T>

All Implemented Interfaces:

BiConsumer<T,Runtime>

Direct Known Subclasses:

AutoCompleteHandler, ComponentHandler, ContextCommandHandler, ModalHandler, SlashCommandHandler

@Internal
public abstract sealed class EventHandler<T extends net.dv8tion.jda.api.events.interaction.GenericInteractionCreateEvent>
extends Object
implements BiConsumer<T,Runtime>
permits AutoCompleteHandler, ComponentHandler, ModalHandler, ContextCommandHandler, SlashCommandHandler

Implementations of this class are handling specific GenericInteractionCreateEvents.

Each EventHandler is split into 3 steps:

1. Preparation (prepare(GenericInteractionCreateEvent, Runtime)): In this step the InvocationContext is created from the jda event and the involved Runtime.

2. Middleware execution: In this step all registered Middlewares are executed ordered by their Priority.

3. Invocation (invoke(InvocationContext, Runtime)): In this step the user implemented method is called with help of the right InteractionDefinition
