| 7 | /* This header exports the declarations for all VT-CROSS radio components. It |
|---|
| 8 | * contains two pure abstract base classes, Component and Engine; Engine derives |
|---|
| 9 | * from Component. All functions contained within the abstract base classes are |
|---|
| 10 | * dynamically linked and pure, and all child non-abstract classes derive using |
|---|
| 11 | * private inheritence. Class functions of the abstract base classes are public |
|---|
| 12 | * for two reasons: (1) To allow for public/protected inheritence in other |
|---|
| 13 | * implementations, (2) So that symbolic debuggers can navigate the call tree |
|---|
| 14 | * for typecasted objects of derivative classes. |
