API Module

The API-module contains interfaces and domain model value classes that provide the basic functionality to build a sdk-client.

Structure

  • api.config - sdk wide configuration and settings
  • api.domain - contains all model classes and domain related pojos
  • api.exceptions - all use case specific the services throw
  • api.services - all services to authenticate, encrypt, validate and perform REST-requests

There are two service facade interfaces that provide a client centric wrapper around the underlying services:

  • Sender - create a submission, announce attachments, encrypt and send the submission including metadata
  • Subscriber - poll, receive and decrypt submissions and confirm their valid transmission

Service Architecture

Apart from the ClientFactory the overall service architecture focuses on composition and has no inherited dependencies.
