BiCOMC

Binary Compatibility Object Model for C++ (BiCOMC) is library for surporting binary compatibility to C++ classes.

Requirements

• C++ 03 or higher support
• __VA_ARGS__ support
• SFINAE support

How to link your project

In general

Just add include to the include directory path.

In CMake 2.8.8 or higher

1. Move to directory of BiCOMC

2. Install BiCOMC (just once)

   mkdir build && cd build
   cmake ..
   cmake --build . --target install

3. Link BiCOMC to your project

   find_package(BiCOMC CONFIG REQUIRED)
   add_executable(YourTarget ...) # or add_library(...)
   target_link_libraries(YourTarget BiCOMC)

In CMake all versions

1. Check the absolute path of include

2. Include the path to your project using include_directories

   include_directories("path/of/bicomc/include")
   add_executable(YourTarget ...) # or add_library(...)

How to use

To define interface

// iprinter.h
#pragma once
#include <bicomc/object.h>
BICOMC_INTERFACE(IPrinter)
	BICOMC_DECL_METHOD(print, void(char const* message), 1)
BICOMC_INTERFACE_END(IPrinter)

To implement interface

// printer.h
#pragma once
#include <iostream>
#include "iprinter.h"
class Printer : public IPrinter {
	BICOMC_OVERRIDE(IPrinter)
		BICOMC_OVER_METHOD(print, void(char const*))
	BICOMC_OVERRIDE_END(IPrinter)
public:
	Printer() : BICOMC_OVERRIDE_INIT() {}
	void print(char const* message) {
		std::cout << message;
	}
};

To instantiate, cast, and call

// main.cpp
#include "printer.h"
int main() {
	bcc::Object* p = new Printer();
	IPrinter& printer = bicomc_cast<IPrinter&>(*p);
	printer.print("Hellow world!!");
	p->destroy(); // as a 'delete p'
	return 0;
}
