Description

InvoiceSummary is an entity 

 

Its collection of getInvoices is a repository query:

@Collection
public List<InvoiceForLease> getInvoices()

{     return invoiceForLeaseRepository.find....(); }

 

Its collection "invoicesDocsFra" is derived, returning view model for each entity.

 

public class InvoiceSummary_invoiceDocsFra {

    private final InvoiceSummary invoiceSummary;

    public List<DocAndCommFra> coll()

{         return invoiceSummary.streamInvoices()                 .map(docAndCommFactory::instantiate)                 .collect(Collectors.toList());     }

}

 

the DocAndCommFra is a view model that wraps each invoice:

@Named(DocAndCommFra.LOGICAL_TYPE_NAMED)
@DomainObject(nature = Nature.VIEW_MODEL)
@DomainObjectLayout
@NoArgsConstructor
@AllArgsConstructor(access = AccessLevel.PACKAGE)
public final class DocAndCommFra {

    public static final String LOGICAL_TYPE_NAMED = "outgoing.invoiceforlease.DocAndCommFra";

    @Property
    @PropertyLayout(sequence = "1")
    @Getter @Setter
    private InvoiceForLease invoice;

    @Property
    @PropertyLayout(sequence = "1.3")
    public Lease getLease()

{         return getInvoice().getLease();     }

    @Property()
    @PropertyLayout(sequence = "1.4")
    public CommunicationChannel getSendTo()

{         return getInvoice().getSendTo();     }

    ...

}

 

it's possible to sort the "docAndCommsFra" table on invoice, and on lease, but not on sendTo.  Note that CommunicationChannel is abstract, subtypes are either EmailAddress or PostalAddress.
