Package-level declarations

This package provides classes and interfaces for backend part of the system.

Some of the classes in this package are also generated from Protobuf. Those classes represent general data structures for working with backend data in a multi-language system.

Classes and interfaces under this package are NOT meant be at the client site of an application.

Types

BoundedContext

public abstract class BoundedContext implements Closeable

A logical and structural boundary of a model.

BoundedContextBuilder

public final class BoundedContextBuilder

A builder for producing BoundedContext instances.

Closeable

public interface Closeable implements AutoCloseable

Base interface for server-side objects that may hold resources that need to be released at the end of the lifecycle of the object.

CommandService

public final class CommandService

The CommandService allows client applications to post commands and receive updates from the application backend.

ConnectionBuilder

public abstract class ConnectionBuilder

Abstract base for builders of objects that depend on or expose server-side gRPC objects.

ContextAware

public interface ContextAware

QueryService

public final class QueryService

The QueryService provides a synchronous way to fetch read-side state from the server.

Server

Exposes one or more Bounded Contexts using CommandService, QueryService and SubscriptionService.

ServerEnvironment

public final class ServerEnvironment implements AutoCloseable

The server conditions and configuration under which the application operates.

SubscriptionService
