Macro Definition Documentation

BIND_EVENT_FN

#define BIND_EVENT_FN

(

x

)

Value:

std::bind(&Application::x, this, std::placeholders::_1)

Binds the given member function of the Application class as an event handler.

Parameters

x	The member function to bind.

BIT

#define BIT

(

x

)

Value:

(1 << x)

Macro to shift 1 by x positions to create a bitmask.

Parameters

x	The number of positions to shift.

Returns

The resulting bitmask.

Note

This macro is typically used for defining event categories.

Warning

Be cautious when using this macro with values greater than or equal to the number of bits in an integer, as it may lead to undefined behavior.

Attention

This macro is not type-safe; consider using constexpr functions or enum classes for better type safety.

EVENT_CLASS_CATEGORY

#define EVENT_CLASS_CATEGORY

(

category

)

Value:

virtual int GetCategoryFlags() const override { return category; }

Macro to define event category in event subclasses.

Parameters

category

The event category to define.

EVENT_CLASS_TYPE

#define EVENT_CLASS_TYPE

(

type

)

Value:

static EventType GetStaticType() { return EventType::##type; }\
virtual EventType GetEventType() const override { return GetStaticType(); }\
virtual const char* GetName() const override { return #type; }

Macro to define event type in event subclasses.

Parameters

type	The event type to define.

#define EVENT_CLASS_TYPE(type) static EventType GetStaticType() { return EventType::##type; }\
                                virtual EventType GetEventType() const override { return GetStaticType(); }\
                                virtual const char* GetName() const override { return #type; }

VZ_BIND_EVENT_FN

#define VZ_BIND_EVENT_FN

(

fn

)

Value:

[this](auto&&... args) -> decltype(auto) { return this->fn(std::forward<decltype(args)>(args)...); }

Binds a member function as an event handler.

Parameters

fn	The member function to bind.
