2.29. Processing a D03B UN/EDIFACT Message Interchange

Reading:

// Create an instance of the EJC generated factory class... cache this and reuse !!!
D03BInterchangeFactory factory = D03BInterchangeFactory.getInstance();
 
// Deserialize the UN/EDIFACT interchange stream to Java...
UNEdifactInterchange interchange = factory.fromUNEdifact(ediInStream);
 
// Need to test which interchange syntax version.  Supports v4.1 at the moment...
if(interchange instanceof UNEdifactInterchange41) {
    UNEdifactInterchange41 interchange41 = (UNEdifactInterchange41) interchange;
 
    for(UNEdifactMessage41 message : interchange41.getMessages()) {
        // Process the messages...
 
        Object messageObj = message.getMessage();
 
        if(messageObj instanceof Invoic) {
            // It's an INVOIC message....
            Invoic invoic = (Invoic) messageObj;
            ItemDescription itemDescription = invoic.getItemDescription();
            // etc etc....
        } else if(messageObj instanceof Cuscar) {
            // It's a CUSCAR message...
        } else if(etc etc etc...) {
            // etc etc etc...
        }
