Type of Business Object

Protected business objects are only used within LN. They have only a protected interface (protected attributes and protected methods), and no public interface. LN functions as a server.

Public business objects have both a public and a protected interface. The public interface is used to exchange information outside the LN applications. LN functions as a server.

Proxy business objects are implemented by external applications for which LN creates a model that is derived from the external application and in compliance with the interfaces offered by that application. LN functions as a client.
