Constructing Functors

To create a functor:

Construct a handle

Bind a callable object to that handle

The simplest way to do this is to bind the callable object handle when it is being constructed.

Example 66 shows the minimal code required for building and using a functor.

Example 66 – Creating and using a functor

#include <rw/functor/RWTFunctor.h>

void func(void);

int main(void) {

// build a functor to encapsulate function func

RWTFunctor<void()> functor = func;

//invoke the functor

functor();

return 0;

}
