C++ Reflection Library

RTTR stands for Run Time Type Reflection.It describes the ability of a computer program to introspect and modify an object at runtime. It is also the name of the library itself, which is written in C++ and released as open source library.You can find more information on:www.rttr.org

#include<rttr/registration>usingnamespacerttr;structMyStruct { MyStruct() {};voidfunc(double) {};int data; };RTTR_REGISTRATION{    registration::class_<MyStruct>("MyStruct")         .constructor<>()         .property("data", &MyStruct::data)         .method("func", &MyStruct::func);}

type t = type::get<MyStruct>();for (auto& prop : t.get_properties())    std::cout <<"name:" << prop.get_name();for (auto& meth : t.get_methods())    std::cout <<"name:" << meth.get_name();

type t = type::get_by_name("MyStruct");variant var = t.create();// will invoke the previously registered ctorconstructor ctor = t.get_constructor();// 2nd way with the constructor classvar = ctor.invoke();std::cout << var.get_type().get_name();// prints 'MyStruct'

MyStruct obj;property prop = type::get(obj).get_property("data");prop.set_value(obj,23);variant var_prop = prop.get_value(obj);std::cout << var_prop.to_int();// prints '23'

MyStruct obj;method meth = type::get(obj).get_method("func");meth.invoke(obj,42.0);variant var = type::get(obj).create();meth.invoke(var,42.0);

• reflect constructors, methods, data member or enums
• classes; withsingle-,multiple- andvirtual-inheritance
• constructors (arbitrary argument count)
• methods (virtual,abstract,overloaded, arbitrary argument count)
• arrays (incl. raw-arrays; arbitrary dimension count)
• ability to invoke properties and methods of classes from any arbitrary class level
• no header pollution; the reflection information is created in the cpp file to minimize compile time when modifying the data
• working with custom types without the need of having the declaration of the type available at compile time (useful for plugins)
• possibility to add additionalmetadata to all reflection objects
• possibility to adddefault arguments to methods or constructors
• adjust registration behaviour throughpolicies
• minimal macro usage
• no additional 3rd party dependencies are needed
• no rtti required; contains a faster and across shared libraries working replacement
• no exceptions (this feature come with cost and is also regularly disabled on consoles)
• no external compiler or tool needed, only standard ISO C++11

Tested and compiled with:

• Microsoft Visual Studio 2015 & 2017 (2013 support till version 0.9.6)
• GCC 4.8.1
• Clang 3.7
• MinGW 4.8.2
