Aurora Interfaces
This library implements the macros required to define Aurora style interfaces. Defines two classes. Implementable by SWIG, CppSharp, and classical OOP override event interface; and implementable by std::function for modern C++ and runtime language bindings respectively. The former is simply defined as a structure containing virtual methods as laid out by AUI_METHODs. Latterly, the base interface is extended and implemented by an array of overloaded method defintions and std::function member fields.
Example usage:
In your common header:
#if defined(MY_LIB_GEN_BINDINGS)
#define LIB_INTERFACE(name, list) AUI_INTERFACE_IMPL(name, list)
#define
#define LIB_INTERFACE(name, list) AUI_INTERFACE_FWD(name, list)
#endif
In your public API:
LIB_INTERFACE(IInputMouseSubscriber,
AUI_METHOD(void, onButtonPress, (AuUInt8, mb)),
AUI_METHOD(void, onButtonTick, (AuUInt8, mb)),
AUI_METHOD(void, onButtonUp, (AuUInt8, mb))
);
In a dedicated translation unit:
#define MY_LIB_GEN_BINDINGS
#include <...>
Usage Runtime Binding and Modern C++
// My language binding
IInputMouseSubscriberFunctional test;
test.onButtonPress = [](AuUInt8 btn)
{
};
AuSPtr<IInputMouseSubscriber> handle = AuUnsafeRaiiToShared(&test);
// use handle with an Aurora API
Usage C++ Native, SWIG, and CppSharp
struct MyEventHandler : public IInputMouseSubscriber
{
void onButtonPress(AuUInt8 mb) override;
void onButtonTick(AuUInt8 mb) override;
void onButtonUp(AuUInt8 mb) override;
};
auto handle = AuMakeShared<MyEventHandler>();
