Package com.opencqrs.framework.command

Interface CommandHandler<I,C extends Command,R>

Type Parameters:

I - the generic type of the instance to be event sourced before handling the command

C - the command type

R - the command execution result type

All Known Subinterfaces:

CommandHandler.ForCommand<I,C,R>, CommandHandler.ForInstanceAndCommand<I,C,R>, CommandHandler.ForInstanceAndCommandAndMetaData<I,C,R>

public sealed interface CommandHandler<I,C extends Command,R>
permits CommandHandler.ForCommand<I,C,R>, CommandHandler.ForInstanceAndCommand<I,C,R>, CommandHandler.ForInstanceAndCommandAndMetaData<I,C,R>

Sealed base interface for inherited FunctionalInterface variants encapsulating command-handling logic. Implementations of this will have to encapsulated into CommandHandlerDefinitions to be executable CommandRouter.send(Command) or CommandRouter.send(Command).
