A function object, or functor, is an object that encapsulates a call to an associated global or member function. When a functor is invoked, it calls the associated function.
The rwtMakeFunctor2() functions and macros are provided to construct functors based on the RWTFunctor2 class. The RWTFunctor2 class acts as the handle for a family of functor implementation classes based on the RWTFunctor2Imp class. A functor based on RWTFunctor2 is invoked with two arguments and returns no value, but the implementation classes can accept functions with up to two additional arguments and any return type. The values for the additional arguments are defined when an implementation class instance is constructed, and are passed to the function each time the functor is invoked.
Each rwtMakeFunctor2() function or macro instantiates and constructs an appropriate functor implementation class instance and returns an RWTFunctor2 handle that is bound to that instance.
rwtMakeFunctor2() comes in two flavors. First, there is a set of overloaded global function templates. Since not all compilers are able to handle templates to the degree required by these functions, we also provide a corresponding set of macros. The template functions are slightly easier to use and you only have to remember one name. The macros are more portable but they do require more arguments; and because we cannot overload macros, each must have a unique name.
In naming the macros, we have employed a convention to make the names easier to remember. Each name begins with rwtMakeFunctor2(), which will be followed by either a G
if the macro is expecting a global function, or an M
if it is expecting a member function. At that point, the name is complete if the associated global or member function takes no additional arguments. Otherwise we add one of A1
or A2
for functions with 1 or 2 additional arguments respectively. For example, you will use macro rwtMakeFunctor2G() to create a functor that calls a global function that takes no additional arguments. The macro rwtMakeFunctor2MA2() will create a functor that calls a member function that takes two additional arguments.

DR | Type name of the function return value. |
function | Global function pointer. |
D1 | Type name of the first argument of the function. |
D2 | Type name of the second argument of the function. |
