isAbstract
A Boolean value that indicates whether the receiver represents an abstract entity.
Declaration
var isAbstract: Bool { get set }Return Value
true if the receiver represents an abstract entity, otherwise false.
Discussion
true if the receiver represents an abstract entity, otherwise false. An abstract entity might be Shape, with concrete sub-entities such as Rectangle, Triangle, and Circle.
Special Considerations
Setting whether an entity is abstract raises an exception if the receiver’s model has been used by an object graph manager.
