Interface Summary

Interface	Description
CommandBus	The mechanism that dispatches Command objects to their appropriate CommandHandler.
CommandBusSpanFactory	Span factory that creates spans for the CommandBus.
CommandCallback<C,R>	Interface describing a callback that is invoked when command handler execution has finished.
CommandMessage<T>	Represents a Message carrying a command as its payload.
CommandMessageHandler	MessageHandler specialization for handlers of Command Messages.
CommandMessageHandlingMember<T>	Interface describing a message handler capable of handling a specific command.
CommandResultMessage<R>	Message that represents a result from handling a CommandMessage.
DuplicateCommandHandlerResolver	Functional interface towards resolving the occurrence of a duplicate command handler being subscribed.

Class Summary

Class	Description
AnnotationCommandHandlerAdapter<T>	Adapter that turns any @CommandHandler annotated bean into a MessageHandler implementation.
AsynchronousCommandBus	Specialization of the SimpleCommandBus that processed Commands asynchronously from the calling thread.
AsynchronousCommandBus.Builder	Builder class to instantiate a AsynchronousCommandBus.
CurrentUnitOfWorkParameterResolverFactory	ParameterResolverFactory that add support for the UnitOfWork parameter type in annotated handlers.
DefaultCommandBusSpanFactory	Default implementation of the CommandBusSpanFactory.
DefaultCommandBusSpanFactory.Builder	Builder class to instantiate a DefaultCommandBusSpanFactory.
DuplicateCommandHandlerResolution	Enumeration describing a set of reasonable DuplicateCommandHandlerResolver implementations.
FailingDuplicateCommandHandlerResolver	Implementation of DuplicateCommandHandlerResolver that throws a DuplicateCommandHandlerSubscriptionException when a duplicate registration is detected.
GenericCommandMessage<T>	Implementation of the CommandMessage that takes all properties as constructor parameters.
GenericCommandResultMessage<R>	Generic implementation of CommandResultMessage.
LoggingDuplicateCommandHandlerResolver	Implementation of the DuplicateCommandHandlerResolver that allows registrations to be overridden by new handlers, but logs this (on WARN level) to a given logger.
MethodCommandHandlerDefinition	Implementation of a HandlerEnhancerDefinition that is used for CommandHandler annotated methods.
MonitorAwareCallback<C,R>	Wrapper for a callback that notifies a Message Monitor of the message execution result.
SimpleCommandBus	Implementation of the CommandBus that dispatches commands to the handlers subscribed to that specific command's name.
SimpleCommandBus.Builder	Builder class to instantiate a SimpleCommandBus.
WrappedCommandCallback<C,R>	Represents a CommandCallback that was wrapped with another.

Exception Summary

Exception	Description
CommandExecutionException	Indicates that an exception has occurred while handling a command.
DuplicateCommandHandlerSubscriptionException	Exception indicating a duplicate Command Handler was subscribed whilst this behavior is purposefully guarded against.
NoHandlerForCommandException	Exception indicating that no suitable command handler could be found for the given command.

Annotation Types Summary

Annotation Type	Description
CommandHandler	Marker annotation to mark any method on an object as being a CommandHandler.
RoutingKey	Field or method level annotation that marks a field or method providing the routing key that a command targets.
