Macro Definition Documentation

#define COMPARE_StateAttribute_Parameter

(

parameter

)

Value:

if (parameter<rhs.parameter) return -1; \
        if (rhs.parameter<parameter) return 1;

COMPARE_StateAttribute_Parameter macro is a helper for implementing the StatateAtribute::compare(..) method.

Macro assumes that variable rhs has been correctly defined by preceding code macro.

#define COMPARE_StateAttribute_Types	(		TYPE,
			rhs_attribute
	)

Value:

if (this==&rhs_attribute) return 0;\
            const std::type_info* type_lhs = &typeid(*this);\
            const std::type_info* type_rhs = &typeid(rhs_attribute);\
            if (type_lhs->before(*type_rhs)) return -1;\
            if (*type_lhs != *type_rhs) return 1;\
            const TYPE& rhs = static_cast<const TYPE&>(rhs_attribute);

COMPARE_StateAttribute_Types macro is a helper for implementing the StateAtribute::compare(..) method.

#define GL_COLOR_SUM   0x8458

#define META_StateAttribute	(		library,
			name,
			type
	)

Value:

virtual osg::Object* cloneType() const { return new name(); } \
        virtual osg::Object* clone(const osg::CopyOp& copyop) const { return new name (*this,copyop); } \
        virtual bool isSameKindAs(const osg::Object* obj) const { return dynamic_cast<const name *>(obj)!=NULL; } \
        virtual const char* libraryName() const { return #library; } \
        virtual const char* className() const { return #name; } \
        virtual Type getType() const { return type; }

META_StateAttribute macro define the standard clone, isSameKindAs, className and getType methods.

Use when subclassing from Object to make it more convenient to define the standard pure virtual methods which are required for all Object subclasses.
