public class TLcdAIXM51Optional<T> extends TLcdDataObject
An optional is a ILcdDataObject with a value property and an optional nil reason property to explain why the value is not filled in.
This class is typically used as a UML association class. This means that it implements
an association between two other classes. The value property (implemented by
getValueObject()
and setValueObject(Object)
) is the role
property of this association. In the large majority of cases, only the value of the
role property is used by applications. In those cases, the association class can be
considered to be a mere wrapper. Because of this, the API of the domain objects was made
such that these association classes are not visible in the API. The getters and setters
for properties of which the type is an association class
directly expose the role property. Wrapping and unwrapping is done automatically by the
implementation.
Only when the application uses the generic ILcdDataObject
API to access
the domain objects, these association classes become visible.
