CommandBuscommand to the CommandHandler subscribed to the given command's name.
No feedback is given about the status of the dispatching process. Implementations may return immediately after
asserting a valid handler is registered for the given command.dispatch in interface CommandBusC - The payload type of the command to dispatchcommand - The Command to dispatchGenericCommandMessage.asCommandMessage(Object)public <C,R> void dispatch(CommandMessage<C> commandMessage, CommandCallback<? super C,? super R> commandCallback)
CommandBuscommand to the CommandHandler subscribed to the given command's name.
When the command is processed, one of the callback's methods is called, depending on the result of the processing.
When the method returns, the only guarantee provided by the CommandBus implementation is that the command has
been successfully received. Implementations are highly recommended to perform basic validation of the command
before returning from this method call.
Implementations must start a UnitOfWork when before dispatching the command, and either commit or rollback after
a successful or failed execution, respectively.dispatch in interface CommandBusC - The payload type of the command to dispatchR - The type of the expected resultcommandMessage - The Command to dispatchcommandCallback - The callback to invoke when command processing is completeGenericCommandMessage.asCommandMessage(Object)public Registration subscribe(String s, MessageHandler<? super CommandMessage<?>> messageHandler)

If a subscription already exists for the given name, the behavior is undefined. Implementations may throw an
Exception to refuse duplicate subscription or alternatively decide whether the existing or new
