36 | @ingroup Class Super |
---|
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 |
