org.axonframework.commandhandling.CommandCallback
Interface describing a callback that is invoked when command handler execution has finished. Depending of the outcome of the execution, either the {@link #onSuccess(Object)} or the {@link #onFailure(Throwable)} is called. @param < R> the type of result of the command handling @author Allard Buijze @since 0.6
