|---|
| 37 |     @brief Definition of all super-function related macros, used to call functions of the base class. | 
|---|
| 38 |  | 
|---|
| 39 |     This file defines all macros needed to add a new "super-function". If you add | 
|---|
| 40 |     a super-function, you can call <tt>SUPER(myclass, functionname, arguments)</tt> | 
|---|
| 41 |     inside your code and the function of the parent-class gets called. This is comparable | 
|---|
| 42 |     to <tt>super.functionname(arguments)</tt> in Java or other languages. | 
|---|
| 43 |  | 
|---|
| 44 |     This works only with virtual functions that return nothing (@c void) and belong to | 
|---|
| 45 |     classes that have an @ref orxonox::Identifier "Identifier". Arguments however are | 
|---|
| 46 |     supported, there's no limitation for their number and type, except that the type has | 
|---|
| 47 |     to be known in Super.h. | 
|---|
| 48 |  | 
|---|
| 49 |     To add a new super-function, you have to process 4 steps: | 
|---|
| 50 |  | 
|---|
| 51 |     -# Add a new @c SUPER macro <br /> | 
|---|
| 52 |        This allows you to call the super-function in your code. <br /> | 
|---|
| 53 |        Location: This file (Super.h), marked with "--> HERE <--" comments (1/3) | 
|---|
| 54 |     -# Call the @c SUPER_FUNCTION_GLOBAL_DECLARATION_PART1/2 macros. <br /> | 
|---|
| 55 |        This defines some global classes and templates, needed to create and call the super-functions. <br /> | 
|---|
| 56 |        Location: This file (Super.h), marked with "--> HERE <--" comments (2/3) | 
|---|
| 57 |     -# Call the @c SUPER_INTRUSIVE_DECLARATION macro. <br /> | 
|---|
| 58 |        This will be included into the declaration of @c ClassIdentifier<T>. <br /> | 
|---|
| 59 |        Location: This file (Super.h), marked with "--> HERE <--" comments (3/3) | 
|---|
| 60 |     -# Call the @c SUPER_FUNCTION macro. <br /> | 
|---|
| 61 |        This defines a partially specialized template that will decide if a class is "super" to another class. | 
|---|
| 62 |        If the check returns true, a @c SuperFunctionCaller gets created, which will be used by the @c SUPER macro. | 
|---|
| 63 |        You have to add this into the header-file of the baseclass of the super-function (the class that first | 
|---|
| 64 |        implements the function), below the class declaration. You can't call it directly in this file, because | 
|---|
| 65 |        otherwise you had to include the headerfile right here, which would cause some ugly back-dependencies, | 
|---|
| 66 |        include loops and slower compilation. <br /> | 
|---|
| 67 |        Dont forget to include Super.h in the header-file. <br /> | 
|---|
| 68 |        Location: The header-file of the baseclass (Baseclass.h), below the class declaration |
