Linked properties #

One is likely to encounter a scenario where a client class derived inherits from tct::cppproperties::properties but also from another, existing base class base. In this case serializing an instance of derived will only contain the properties created with MAKE_PROPERTY. However, one might like (or need) to also include members of the base class although these are not properties registered in the base class.

The macro LINK_PROPERTY() may be used to include members of a base class as a property.

Complete example demonstrating the use of linked properties:

#include "cppproperties/properties.hpp"

struct base
{
    int x = 0;
    int y = 0;
};

struct derived :
    base,
    tct::cppproperties::properties
{
    derived()
    {
        LINK_PROPERTY(x, &x);
        LINK_PROPERTY(y, &y);
    }
};

int main()
{
    derived d;
    d.x = 42;
    d.y = 1337;
}
