Class TLcdAIXM51Optional<T>

All Implemented Interfaces:
ILcdDataObject, ILcdCloneable, ILcdDeepCloneable, Cloneable

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.
