| [7401] | 36 | @ingroup Class Super | 
|---|
|  | 37 | @brief Definition of all super-function related macros, used to call functions of the base class. | 
|---|
| [1684] | 38 |  | 
|---|
| [7401] | 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. | 
|---|
| [1684] | 43 |  | 
|---|
| [7401] | 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. | 
|---|
| [1684] | 48 |  | 
|---|
| [7401] | 49 | To add a new super-function, you have to process 4 steps: | 
|---|
| [1684] | 50 |  | 
|---|
| [7401] | 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 /> | 
|---|
| [1684] | 61 | This defines a partially specialized template that will decide if a class is "super" to another class. | 
|---|
| [7401] | 62 | If the check returns true, a @c SuperFunctionCaller gets created, which will be used by the @c SUPER macro. | 
|---|
| [1684] | 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 | 
|---|
| [7401] | 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 /> | 
|---|
| [1684] | 68 | Location: The header-file of the baseclass (Baseclass.h), below the class declaration |
