    Definitely easier for someone inheriting that code to see the business logic than direct calls to item values and view lookups.

    Java has a handy notion called "Iterable": any class that claims to implement that feature can use a very terse looping syntax. So if you were writing these same classes in Java, and InvoiceCollection implemented Iterable, then this syntax:

    if (customer.getInvoices().getCount() > 0) {

    invoice = customer.getInvoices().getFirst();

    while (invoice != null) {

    // Do what you like here

    invoice = customer.getInvoices().getNext();



    ...can be shortened all the way to:

    for (Invoice invoice : customer.getInvoices()) {

    // Do what you like here


    It's like Forall in LotusScript without all the messy Variant side effects. :)
