Interface Summary

Interface	Description
CommandBus	The mechanism that dispatches Command objects to their appropriate CommandHandler.
CommandCallback<R>	Interface describing a callback that is invoked when command handler execution has finished.
CommandDispatchInterceptor	Interceptor that allows commands to be intercepted and modified before they are dispatched by the Command Bus.
CommandHandler<T>	Marks an instance that is capable of handling commands.
CommandHandlerInterceptor	Workflow interface that allows for customized command handler invocation chains.
CommandMessage<T>	Represents a Message carrying a command as its payload.
CommandTargetResolver	Interface towards a mechanism that is capable of extracting an Aggregate Identifier and Version form a command that identifies the aggregate instance the command should be invoked on.
InterceptorChain	The interceptor chain manages the flow of a command through a chain of interceptors and ultimately to the command handler.
RollbackConfiguration	The RollbackConfiguration defines when a UnitOfWork should be rolled back when the command handler or any interceptors reported a failure.
SimpleCommandBusStatisticsMXBean	Management interface for the SimpleCommandBus monitor As required by the JMX specification.

Class Summary

Class	Description
AsynchronousCommandBus	Specialization of the SimpleCommandBus that processed Commands asynchronously from the calling thread.
DefaultInterceptorChain	Mechanism that takes care of interceptor and event handler execution.
GenericCommandMessage<T>	Implementation of the CommandMessage that takes all properties as constructor parameters.
MetaDataCommandTargetResolver	CommandTargetResolver implementation that uses MetaData entries to extract the identifier and optionally the version of the aggregate that the command targets.
RollbackOnAllExceptionsConfiguration	The default implementation of the RollbackConfiguration interface.
RollbackOnUncheckedExceptionConfiguration	RollbackConfiguration that indicates a rollback should be triggered for all but checked exceptions.
SimpleCommandBus	Implementation of the CommandBus that dispatches commands to the handlers subscribed to that specific type of command.
SimpleCommandBusStatistics	Statistics object to store information about the internals of the SimpleCommandBus.
VersionedAggregateIdentifier	Structure that holds an Aggregate Identifier and an expected version of an aggregate.

Exception Summary

Exception	Description
CommandExecutionException	Indicates that an exception has occurred while handling a command.
NoHandlerForCommandException	Exception indicating that no suitable handler could be found for the given command.
StructuralCommandValidationFailedException	Exception indicating that a Command has been refused due to a structural validation failure.
