C++ form function module

The following example of a form function in C++ declares structures for input and output with help of serialization. If you have a function with an empty input or empty output (procedure) then you can use the predefined structure _Wolframe::serialize::EmptyStruct for that.

#include "appdevel/moduleFrameMacros.hpp"
#include "appdevel/cppFormFunctionModuleMacros.hpp"
#include "serialize/struct/structDescription.hpp"

struct MyInput
{
        std::string data;
        int id;
        // ... your data structures are here

        static const _Wolframe::serialize::StructDescriptionBase *getStructDescription();
};

class MyInputDescription :public _Wolframe::serialize::StructDescription<MyInput>
{
public:
        MyInputDescription()
        {
                // here you define introspection for your data:
                (*this)
                        ("data", &MyInput::data)
                        ("id", &MyInput::id)
                ;
        }
};

const _Wolframe::serialize::StructDescriptionBase* MyInput::getStructDescription()
{
        static MyInputDescription rt;
        return &rt;
}

struct MyOutput
{
        // ... your data structures are here as in MyInput

        static const _Wolframe::serialize::StructDescriptionBase *getStructDescription()
        {
                // ... your data structure description is here as for MyInput
        }
};


int myFunction( _Wolframe::proc::ExecContext* ctx, MyOutput& res, const MyInput& param)
{
        // ... your function implementation is here
        // ... it returns 0 on success or else an error code
}
