Interface EventTypeClassifier<E,T>

Type Parameters:

E - Event

T - Event Type

public interface EventTypeClassifier<E,T>

A functional interface to determine the event type of an event. In Machina you can either define Events and Event Types to be the same (simple approach) or you can separate the two and have complex event objects that carry a certain payload. Events can be accessed in guards. To determine the type of an even you can either build your state machine with StateMachineBuilder.withEventTypeClassifier(EventTypeClassifier) or have your Events implement EventWithType.
