Final (Class Keyword)

Specifies whether this class is final (cannot have subclasses).


To specify that a class is final, use the following syntax:

Class MyApp.Exam As %Persistent [ Final ]  { //class members }

Otherwise, omit this keyword or place the word Not immediately before the keyword.


If a class is final, it cannot have subclasses.

Also, if a class is final, the class compiler may take advantage of certain code generation optimizations (related to the fact that instances of a final class cannot be used polymorphically).


If you omit this keyword, the class definition is not final.
