RTTI_BASE_CLASS_PRIVATE

#define RTTI_BASE_CLASS_PRIVATE   const RTTI _classType;

RTTI_BASE_CLASS_PROTECTED_CONSTRUCTOR

#define RTTI_BASE_CLASS_PROTECTED_CONSTRUCTOR

(

BASE_CLASS

)

Value:

BASE_CLASS(RTTI classType) : _classType(classType) { \
    }

RTTI_BASE_CLASS_PUBLIC

#define RTTI_BASE_CLASS_PUBLIC   const RTTI getClassType() const { return _classType; }

RTTI_BASE_CLASS_TREE

#define RTTI_BASE_CLASS_TREE

(

...

)

Value:

enum RTTI{ __VA_ARGS__ }; \
    static RTTI _rttiTree;

Creates an enum of an entire class tree.

Each class is specified with two entries Each branch starts with _FT_X and ends with _LT_X.

{_FT_Shape, _FT_Square, _FT_Rectangle, _LT_Rectangle, _LT_Square, _FT_Ellipse, _FT_Circle, _LT_Circle, _LT_Ellipse, _LT_Shape }

This macro should be specified in the protected section of your base class

RTTI_PROTECTED_CONSTRUCTOR

#define RTTI_PROTECTED_CONSTRUCTOR	(		PARENT_CLASS,
			THIS_CLASS
	)

Value:

THIS_CLASS(RTTI classType) : PARENT_CLASS(classType) { \
    }

RTTI_PUBLIC_DEFAULT_CONSTRUCTOR

#define RTTI_PUBLIC_DEFAULT_CONSTRUCTOR	(		THIS_CLASS,
			RTTI_TYPE
	)

Value:

THIS_CLASS() : THIS_CLASS(_FT_##RTTI_TYPE) { \
    }

RTTI_PUBLIC_METHODS

#define RTTI_PUBLIC_METHODS	(		BASE_CLASS,
			RTTI_TYPE
	)

Value:

static bool isTypeOf(const BASE_CLASS *clazz) { \
        const RTTI rttiType = clazz->getClassType(); \
        return (rttiType >= _FT_##RTTI_TYPE && rttiType <= _LT_##RTTI_TYPE); \
    }

This macro should be specified in the public section of all classes that derive from the base class.

Parameters

BASE_CLASS	- This specifies the actual base class name
RTTI_TYPE	- This specifies the root part of the RTTI part (without FT or LT)
