A

addAsyncSubscriber(EventHandler<EVENT_TYPE>) - Method in class dk.cloudcreate.essentials.reactive.LocalEventBus

Add an asynchronous subscriber/consumer

addCommandHandler(CommandHandler) - Method in class dk.cloudcreate.essentials.reactive.command.LocalCommandBus

Add a new command handler.

addSyncSubscriber(EventHandler<EVENT_TYPE>) - Method in class dk.cloudcreate.essentials.reactive.LocalEventBus

Add a synchronous subscriber/consumer

AnnotatedCommandHandler - Class in dk.cloudcreate.essentials.reactive.command

Extending this class will allow you to colocate multiple related Command handling methods inside the same class and use it together with the LocalCommandBus
Each method must accept a single Command argument, may return a value or return void and be annotated with the EventHandler annotation.
The method argument type is matched against the concrete command type using Class.isAssignableFrom(Class).
The method accessibility can be any combination of private, protected, public, etc.
Example:

AnnotatedCommandHandler() - Constructor for class dk.cloudcreate.essentials.reactive.command.AnnotatedCommandHandler

AnnotatedEventHandler<EVENT_TYPE> - Class in dk.cloudcreate.essentials.reactive

Extending this class will allow you to colocate multiple related Event handling methods inside the same class and use it together with the LocalEventBus
Each method must accept a single Event argument, return void and be annotated with the EventHandler annotation.
The method argument type is matched against the concrete event type using Class.isAssignableFrom(Class).
The method accessibility can be any combination of private, protected, public, etc.
Example:

AnnotatedEventHandler() - Constructor for class dk.cloudcreate.essentials.reactive.AnnotatedEventHandler

AsyncEventHandler - Annotation Type in dk.cloudcreate.essentials.reactive.spring

Annotate an EventHandler/AnnotatedEventHandler with this annotation to have the EventHandler be registered as an asynchronous event-handler with the default LocalEventBus (default is registering them as a synchronous event handler).

C

canHandle(Class<?>) - Method in class dk.cloudcreate.essentials.reactive.command.AnnotatedCommandHandler

canHandle(Class<?>) - Method in interface dk.cloudcreate.essentials.reactive.command.CommandHandler

This method is called by the LocalCommandBus to check if this concrete CommandHandler supports a given command type

CommandHandler - Interface in dk.cloudcreate.essentials.reactive.command

Common interface for all Command message handlers
A command handler can choose support to 1 or more command types

commandType - Variable in exception dk.cloudcreate.essentials.reactive.command.SendCommandException

D

dk.cloudcreate.essentials.reactive.spring - package dk.cloudcreate.essentials.reactive.spring

E

event - Variable in exception dk.cloudcreate.essentials.reactive.PublishException

EventHandler<EVENT_TYPE> - Interface in dk.cloudcreate.essentials.reactive

Common interface for all Event message handlers

F

findCommandHandlerCapableOfHandling(Object) - Method in class dk.cloudcreate.essentials.reactive.command.LocalCommandBus

Find a CommandHandler capable of handling the given command

H

handle(EventHandler<EVENT_TYPE>, EVENT_TYPE, Exception) - Method in interface dk.cloudcreate.essentials.reactive.OnErrorHandler

Will be called if a given consumer/subscriber fails to handle a message

handle(EVENT_TYPE) - Method in class dk.cloudcreate.essentials.reactive.AnnotatedEventHandler

handle(EVENT_TYPE) - Method in interface dk.cloudcreate.essentials.reactive.EventHandler

handle(Object) - Method in class dk.cloudcreate.essentials.reactive.command.AnnotatedCommandHandler

handle(Object) - Method in interface dk.cloudcreate.essentials.reactive.command.CommandHandler

This method is called by the LocalCommandBus after it has determined that only this CommandHandler instance is capable of handling the command (based on the commands type)

Handler - Annotation Type in dk.cloudcreate.essentials.reactive

Method annotation that can be applied to any single argument method inside AnnotatedCommandHandler or AnnotatedEventHandler.
Depending on which class you extend the rules that apply to each method may be different.
Common for all is that the method accessibility can be any combination of private, protected, public, etc.

hasAsyncSubscriber(EventHandler<EVENT_TYPE>) - Method in class dk.cloudcreate.essentials.reactive.LocalEventBus

hasCommandHandler(CommandHandler) - Method in class dk.cloudcreate.essentials.reactive.command.LocalCommandBus

hasSyncSubscriber(EventHandler<EVENT_TYPE>) - Method in class dk.cloudcreate.essentials.reactive.LocalEventBus

L

LocalCommandBus - Class in dk.cloudcreate.essentials.reactive.command

The LocalCommandBus provides an indirection between a command and the CommandHandler that's capable of handling the command.
Commands can be sent synchronously using LocalCommandBus.send(Object) or asynchronously using LocalCommandBus.sendAsync(Object) that returns a Mono.
The handling of a command usually doesn't return any value (according to the principles of CQRS), however the LocalCommandBus API allows a CommandHandler to return a value if needed (e.g.

LocalCommandBus() - Constructor for class dk.cloudcreate.essentials.reactive.command.LocalCommandBus

LocalEventBus<EVENT_TYPE> - Class in dk.cloudcreate.essentials.reactive

Simple event bus that supports both synchronous and asynchronous subscribers that are registered and listening for events published within the local the JVM
You can have multiple instances of the LocalEventBus deployed with the local JVM, but usually one event bus is sufficient.

Example:

LocalEventBus(String, int, OnErrorHandler<EVENT_TYPE>) - Constructor for class dk.cloudcreate.essentials.reactive.LocalEventBus

Create a LocalEventBus with the given name, the given number of parallel asynchronous processing threads

LocalEventBus(String, Scheduler, OnErrorHandler<EVENT_TYPE>) - Constructor for class dk.cloudcreate.essentials.reactive.LocalEventBus

Create a LocalEventBus with the given name, the given number of parallel asynchronous processing threads

M

MultipleCommandHandlersFoundException - Exception in dk.cloudcreate.essentials.reactive.command

MultipleCommandHandlersFoundException(Class<?>, String) - Constructor for exception dk.cloudcreate.essentials.reactive.command.MultipleCommandHandlersFoundException

N

NoCommandHandlerFoundException - Exception in dk.cloudcreate.essentials.reactive.command

NoCommandHandlerFoundException(Class<?>, String) - Constructor for exception dk.cloudcreate.essentials.reactive.command.NoCommandHandlerFoundException

O

OnErrorHandler<EVENT_TYPE> - Interface in dk.cloudcreate.essentials.reactive

Error Handler interface for the LocalEventBus

P

postProcessAfterInitialization(Object, String) - Method in class dk.cloudcreate.essentials.reactive.spring.ReactiveHandlersBeanPostProcessor

postProcessBeforeDestruction(Object, String) - Method in class dk.cloudcreate.essentials.reactive.spring.ReactiveHandlersBeanPostProcessor

publish(EVENT_TYPE) - Method in class dk.cloudcreate.essentials.reactive.LocalEventBus

Publish the event to all subscribers/consumer
First we call all asynchronous subscribers, after which we will call all synchronous subscribers on the calling thread (i.e.

PublishException - Exception in dk.cloudcreate.essentials.reactive

PublishException(String, Object) - Constructor for exception dk.cloudcreate.essentials.reactive.PublishException

PublishException(String, Throwable, Object) - Constructor for exception dk.cloudcreate.essentials.reactive.PublishException

R

ReactiveHandlersBeanPostProcessor - Class in dk.cloudcreate.essentials.reactive.spring

When using Spring or Spring Boot it will be easier to register the LocalEventBus, LocalCommandBus, CommandHandler and EventHandler instances as @Bean or @Component and automatically have the CommandHandler beans registered as with the single LocalCommandBus bean and the EventHandler beans registered as subscribers with the single LocalEventBus bean.
