Syntax

public class MessageHandler : IBuildable<MessageHandler, MessageHandler.Builder>, IInputChannel

Remarks

The handler can be constructed in two ways: using MessageHandler.Builder and through inheritance. If you choose the inheritance then message handlers must be declared as public instance methods with one of the following signatures:

// duplex message handlers
Task<Result> HandleAsync(InputMessage input, CancellationToken token);
Task<Result> HandleAsync(ISubscriber sender, InputMessage input, CancellationToken token);
Task<Result> HandleAsync(InputMessage input, object? context, CancellationToken token);
Task<Result> HandleAsync(ISubscriber sender, InputMessage input, object? context, CancellationToken token);
// signal message handlers
Task HandleAsync(InputMessage input, CancellationToken token);
Task HandleAsync(ISubscriber sender, InputMessage input, CancellationToken token);
Task HandleAsync(InputMessage input, object? context, CancellationToken token);
Task HandleAsync(ISubscriber sender, InputMessage input, object? context, CancellationToken token);

Otherwise, command handlers can be registered through the builder.
