SubclassIdentifier

Description

The SubclassIdentifier acts like an Identifier. You can assign a ClassIdentifier and compare it with other Identifiers by using isA(…), isChildOf(…) and other functions.

SubclassIdentifier is a template?. The template?-class defines the needed base-class of an assigned Identifier. You can only assign Identifiers representing a class which is derived from the given base-class (or the base-class itself). If you try to assign an Identifier that's not derived from the base-class, you get an error.

Usage: SubclassIdentifier<BaseClass> name = Class(SubClass); where SubClass isA BaseClass.

Examples

The following examples use the class-tree below.

SubclassIdentifier<A1> myidentifier = Class(A1);             // This works
SubclassIdentifier<A1> myidentifier = Class(A1B1);           // This works
SubclassIdentifier<A1> myidentifier = Class(A1B1C1);         // This works
SubclassIdentifier<A1> myidentifier = Class(BaseObject);     // This doesn't work
SubclassIdentifier<A1> myidentifier = Class(A3);             // This doesn't work


SubclassIdentifier<Interface1> myidentifier = Class(A3);     // This works
SubclassIdentifier<Interface1> myidentifier = Class(A2B2C1); // This works


SubclassIdentifier<A1> myidentifier = Class(A1B1);
myidentifier.isExactlyA(Class(A1));       // Returns false
myidentifier.isExactlyA(Class(A1B1));     // Returns true
(*myidentifier)->getName();               // Returns "A1B1"
myidentifier->getName();                  // Returns "A1B1" (Yes, the "->" is correct. It's overloaded.)

A1* newobject = myidentifier.fabricate(); // Returns a new instance of A1B1, downcasted to A1
