Function manual reflection

For the example, we will manually reflect the following function:

//ThirdPartyFunc.h
inline int thirdPartyFunction(int i, float j) { return i + (int)j; }

Create a function to build the function metadata

In any source file, create a function to create our function metadata:

#include "ThirdPartyFunc.h"
#include <string_view>
#include <Refureku/TypeInfo/Functions/Function.h>

static rfk::Function const& getFunction_thirdPartyFunction() noexcept
{
	static bool initialized = false;
	static rfk::Function func("thirdPartyFunction",
							  std::hash<std::string_view>()("thirdPartyFunction"),
							  rfk::getType<int>(),
							  new rfk::NonMemberFunction<int(int, float)>(&thirdPartyFunction),
							  rfk::EFunctionFlags::Inline);

	if (!initialized)
	{
		initialized = true;

		func.setParametersCapacity(2);
		func.addParameter("i", std::hash<std::string_view>()("thirdPartyFunction i"), rfk::getType<int>());
		func.addParameter("j", std::hash<std::string_view>()("thirdPartyFunction j"), rfk::getType<float>());
	}

	return func;
}

Register to the database

In any cpp file, write the following:

#include <Refureku/TypeInfo/Entity/DefaultEntityRegisterer.h>

rfk::DefaultEntityRegisterer registerer_thirdPartyFunction = getFunction_thirdPartyFunction();
