The pages covers what a developer needs to know to develop an adaptor. using the YOUnite SDK for Adaptors.

For more information on YOUnite adaptors see:

  • TheĀ Introduction to YOUnite covers the core concepts of how YOUnite implements federated MDM with adaptors.
  • The Adaptors page gives more detail on how adaptors work and how they are created and managed.

Adaptor Components

Adaptor Lifecycle

  1. Adaptor registration: POST on API to register (create) an adaptor.
  2. Adaptor start up: When an Adaptor process comes up, as part of the handshake, it sends an Adaptor ready message to the router. For example:

     
    // Create MessageServiceConfiguration builder to
    // build MessageServiceConfiguration and use it to get MessageService instance.
    // Use MessageService for interaction with router via message bus.
    MessageServiceConfiguration.Builder builder = MessageServiceConfiguration.newConfiguration();
    MessageServiceConfiguration msConf = builder.setBrokerUrl("nio+ssl://docker.local:61617"). setJmsClientId(jmsClientId).build();
    
    try {
    	MessageService messageService = MessageServiceFactory.getMessageService(msConf);
    	messageService.setListener(Constants.MessageType.OPS, adminListener); // Listener for OPS messages
    	messageService.setListener(Constants.MessageType.DATA, dataListener); // Listener for Data messages
    
    	// Create AdaptorUp object for conveying the bootstrap information regarding this adaptor
    	AdaptorUp adaptorUp = new AdaptorUp();
     	adaptorUp.setStatus("RUNNING");
     	Map<String, String> capabilities = new HashMap<>();
    
    	// Add Capabilities List
    	adaptorUp.setCapabilities(capabilities);
     	ObjectMapper objectMapper = new ObjectMapper();
     	objectMapper.configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false);
     	String upMessage = objectMapper.writeValueAsString(adaptorUp);
    
    	// Send an OPS message to the router via the Message Broker
    	messageService.sendMessage(Constants.MessageType.OPS, upMessage);  // Send Adaptor Up on OPS channel.
    }
    catch {...}
    
    // If everything goes fine, then the adminListener is notified by the router as it announces the initial state of this Adaptor.
    // If there is a problem, then the dataListener is notified of the error message.
