一個簡單而功能強大的C++反射系統：eXtendedMirror

eXtendedMirror是一個簡單而功能強大的C++反射系統。它具有以下特性：

• Compiler Independent
• Non intrusive
• No mandatory parser required
• Variant based interface
• Dry-est possible interface
</ul>

它支持語言（有一些限制）幾乎所有的構建體如：

• Primitive Types
• Pointer Types
• References
• C Array Types
• Classes
• Multiple Inheritance
• Abstract Classes
• Methods
• Static Functions
• Namespaces
• Class Templates
• Constants
• Enumerators
• Static and Global Variables

You can find a lot of useful information in this article.

The code only depends on the c++11 standard library, but the build system depends on CMake and Python To generate the documentation you need Doxygen

構建

To build the library you first have to run CMake from the project directory

cmake -DCMAKE_BUILD_TYPE=Debug .

You can change Debug with Release if you want, and you can set some other parameters such as

• FUNC_PARAM_MAX: maximum number of supported function parameters (defaults to 8).
• GET_N_SET_EXTR_PARAM_MAX: Maximum number of supported extra parameters for getters and setters, that is the maximum number of parameters for getters, and the maximum number of parameters for setters, beyond the first (i.e. the value to set) (defaults to 3).
• TEMPL_PARAM_MAX: Maximum number of supported template parameters, for class templates (defaults to 4).

After running CMake, you can build the library and the tests by running

make

To install on your system type

make install

To build the documentation

make doc

Using the library

To use the library include the header XM/xMirror.hpp in your compile units and link to the libxMirror library. You can get more info here

MyClass.hpp

#include<XM/xMirror.h>

class MyClass {
public:
    int myMethod(int a, int b);
    int myField;

    int getMyField2();
    void setMyField2(int val);

private:
    int myField2;
};
XM_DECLARE_CLASS(MyClass);




MyClass.cpp

// Methods definition here

XM_DEFINE_CLASS(MyClass)
{
    // Binds a method with automatic name extrapolation
    bindMethod(XM_MNP(myMethod));

    // Binds a property from a field
    bindProperty(XM_MNP(myField));

    // Binds a property from get and set methods
    bindProperty("myField2", &MyClass::getMyField2, &MyClass::setMyField2);
}

XM_REGISTER_TYPE(MyClass);
