Class	Description
Command	Interface to be implemented by commands that can be handled by CommandHandlers.
Command.SubjectCondition	The subject condition checked before CommandHandler execution.
CommandEventCapturer<I>	Default implementation of CommandEventPublisher used by CommandRouter to apply events to the StateRebuildingHandlers relevant for the Command being executed.
CommandEventPublisher<I>	Extension to EventPublisher providing additional operations for publishing events relative to the Command.getSubject() being handled.
CommandHandler<I,C extends Command,R>	Sealed base interface for inherited FunctionalInterface variants encapsulating command-handling logic.
CommandHandler.ForCommand<I,C extends Command,R>	FunctionalInterface to be implemented, if only the Command is needed for execution.
CommandHandler.ForInstanceAndCommand<I,C extends Command,R>	FunctionalInterface to be implemented, if Command and event-sourced instance are needed for execution.
CommandHandler.ForInstanceAndCommandAndMetaData<I,C extends Command,R>	FunctionalInterface to be implemented, if Command, meta-data, and event-sourced instance are needed for execution.
CommandHandlerConfiguration	Annotation to be used for Configurations containing CommandHandling annotated methods, CommandHandlerDefinition Beans, @StateRebuilding annotated methods, and StateRebuildingHandlerDefinition Beans in order to be able to test them using CommandHandlingTest.
CommandHandlerDefinition<I,C extends Command,R>	CommandHandler definition suitable for being processed by the CommandRouter.
CommandHandling	Annotation to be used in favor of defining CommandHandlerDefinition Beans.
CommandHandlingAnnotationProcessingAutoConfiguration	Auto-configuration for CommandHandlerDefinitions defined via CommandHandling annotated bean methods.
CommandHandlingTest	Annotation that can be used for Spring Boot tests that focus only on CQRS CommandHandlerDefinitions in favor of initializing CommandHandlingTestFixture manually.
CommandHandlingTestAutoConfiguration	Auto-configuration for CommandHandlingTestFixtures.
CommandHandlingTestFixture<C extends Command>	Test support for CommandHandler or CommandHandlerDefinition.
CommandHandlingTestFixture.Builder<I>	Builder for CommandHandlingTestFixture.
CommandHandlingTestFixture.EventAsserter	Fluent API helper class for asserting captured events.
CommandHandlingTestFixture.Expect	Fluent API helper class encapsulating the results of a CommandHandler execution for assertion.
CommandRouter	Command router implementation providing CQRS-style command execution.
CommandRouterAutoConfiguration	Auto-configuration for CommandRouter and StateRebuildingCache default implementations.
CommandSubjectAlreadyExistsException	Exception thrown if Command.SubjectCondition.PRISTINE is violated.
CommandSubjectConditionViolatedException	Exception thrown if Command.SubjectCondition is violated.
CommandSubjectDoesNotExistException	Exception thrown if Command.SubjectCondition.EXISTS is violated.
EventAsserting	Interface for comprehensive assertions on captured events, providing access to payload, meta-data, and subject.
EventSpecifierDsl	Fluent API for specifying the attributes of a single given event.
ExpectDsl	DSL interfaces for the "Expect" (or "Then") phase of command handling tests.
ExpectDsl.All	Fluent API for asserting against all captured events.
ExpectDsl.EventValidator	Fluent API interface for validating individual captured events.
ExpectDsl.Failing	Fluent API for assertions after failed command execution.
ExpectDsl.Next	Fluent API for asserting against events sequentially using a consuming cursor.
ExpectDsl.Outcome	Entry point for specifying whether the command execution is expected to succeed or fail.
ExpectDsl.Succeeding	Fluent API for assertions after successful command execution.
GivenDsl<C extends Command>	Fluent API for configuring test preconditions before command execution.
GivenDsl.Initial<C extends Command>	Entry point for the Given phase, returned by CommandHandlingTestFixture.given().
GivenDsl.Terminated<C extends Command>	Terminal state of the Given phase after calling GivenDsl.Initial.nothing().
SourcingMode	The type of sourcing affecting which events will be sourced for CommandHandlers.
StateRebuilding	Annotation to be used in favor of defining StateRebuildingHandlerDefinition Beans.
StateRebuildingAnnotationProcessingAutoConfiguration	Auto-configuration for StateRebuildingHandlerDefinitions defined via StateRebuilding annotated bean methods.
StateRebuildingHandler<I,E>	Sealed base interface for inherited FunctionalInterface variants encapsulating the event-sourcing logic needed to reconstruct instance state from an event stream.
StateRebuildingHandler.FromObject<I,E>	FunctionalInterface to be implemented, if only the Java event is needed to reconstruct the instance state.
StateRebuildingHandler.FromObjectAndMetaData<I,E>	FunctionalInterface to be implemented, if the Java event and its meta-data is needed to reconstruct the instance state.
StateRebuildingHandler.FromObjectAndMetaDataAndSubject<I,E>	FunctionalInterface to be implemented, if the Java event, its meta-data, and subject is needed to reconstruct the instance state.
StateRebuildingHandler.FromObjectAndMetaDataAndSubjectAndRawEvent<I,E>	FunctionalInterface to be implemented, if the Java event, its meta-data, subject, and optional raw event is needed to reconstruct the instance state.
StateRebuildingHandler.FromObjectAndRawEvent<I,E>	FunctionalInterface to be implemented, if the Java event and the raw Event is needed to reconstruct the instance state.
StateRebuildingHandlerDefinition<I,E>	StateRebuildingHandler definition suitable for event-sourcing an instance prior to command handling.
