Forward Reference
|
|
|
The Vera language supports the typedef class construct for forward referencing of a class declaration. This allows for the compiler to read a file from beginning to end without concern for the positioning of the class declaration. |

1 typedef class A;
2
3 class B {
4 A a;
5 task new () {
6 a = new();
7 a.print();
8 }
9 }
10
11 program forward_ref {
12 B b = new();
13 }
