c++ - Is it possible to create a container that holds one of three data types, and can be queried through a single interface? -

i have container object holds either int, float or string. have queue of these containers processed in similar way. @ moment have separate getters different data types. isn't particularly elegant, given each container instance hold 1 data type @ time.

class mycontainer {     mycontainer(float value);     mycontainer(int value);     mycontainer(string value);      int getintvalue();     float getfloatvalue();     string getstringvalue(); }  void processcontainer(mycontainer& container) {     // following not work, desired:     process(container->getvalue()); // compilation error }  void process(int value) {} void process(float value) {} void process(string value) {} 

is there way can exploit parameter overloading of process method above? example, way of getting point can call process(container->getvalue())?

you can use templates , traits restrict templated code types string, float, int.
