public interface ILcdService extends ILcdDataObject
Attributes and relationships in AIS domain objects can be required or optional. When unspecified, an attribute or relationship is optional. Note that most optional attributes are modeled using features.
In future releases of AIS, optional attributes or relationship may be added to this interface. When this would happen, existing implementations may just return a specified default value for these new attributes or relationships (for instance 'null'). This will require a minimal effort to update existing code to a new version of AIS.
