---|
[9667] | 37 | @brief Defines several very important macros used to register objects, register classes, and to work with identifiers. |
---|
[1505] | 38 | |
---|
[9667] | 39 | Every class needs the @c RegisterObject(class) macro in its constructor. |
---|
[1505] | 40 | |
---|
[9667] | 41 | To register @a class in the class-hierarchy, use the @c RegisterClass(class) macro outside of the class implementation, |
---|
| 42 | so it gets executed statically before @c main(). If you don't want @a class to be loadable, but still register it, call |
---|
| 43 | @c RegisterUnloadableClass(class). |
---|
[7401] | 44 | |
---|
[9667] | 45 | Abstract classes are registered with @c RegisterAbstractClass(class). For abstract classes, the inheritance must be |
---|
| 46 | defined manually with @c RegisterAbstractClass(class).inheritsFrom(Class(parent)). Multiple parent classes can be defined |
---|
| 47 | by chaining the above command. |
---|
| 48 | |
---|
[7401] | 49 | Example: |
---|
| 50 | @code |
---|
[9667] | 51 | // register MyClass |
---|
| 52 | RegisterClass(MyClass); |
---|
[7401] | 53 | |
---|
| 54 | // Constructor: |
---|
| 55 | MyClass::MyClass() |
---|
| 56 | { |
---|
| 57 | // Register the object in the Identifier of MyClass |
---|
| 58 | RegisterObject(MyClass); |
---|
| 59 | } |
---|
| 60 | @endcode |
---|
| 61 | |
---|
| 62 | This file also defines a number of other useful macros, like, for example, @c Class(class) which |
---|
| 63 | returns the @ref orxonox::Identifier "Identifier" of @a class, or @c ClassByString("class") which |
---|
| 64 | returns the Identifier of a class with name @a "class". |
---|
| 65 | |
---|
| 66 | Example: |
---|
| 67 | @code |
---|
| 68 | // Assigns the Identifier of MyClass |
---|
| 69 | Identifier* identifier = Class(MyClass); |
---|
| 70 | @endcode |
---|
| 71 | @code |
---|
| 72 | // Assigns the Identifier of a class named "MyClass" |
---|
| 73 | Identifier* identifier = ClassByString("MyClass"); |
---|
| 74 | @endcode |
