The rwtMakeRunnableCallback() helper functions and macros create functors that may be passed to the addCallback() method of an RWRunnableHandle. The functor may be created from functions that accept a constant RWRunnable reference as first argument, and an RWExecutionState as second argument, and that do not return a value.

rwtMakeRunnableCallback() 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 as 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 rwtMakeRunnableCallback(), 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 rwtMakeRunnableCallbackG() to create a runnable that calls a global function that takes no arguments other than the runnable reference and the execution state. The macro rwtMakeRunnableCallbackMA2() will create a runnable that calls a member function that takes four arguments: the runnable reference and the execution state, plus two user-supplied arguments.

// Global function with no additional arguments
void function(const RWRunnable&, RWExecutionState);
RWRunnableHandle rnb = ...;
// Create callback for function() and register with runnable
rnb.addCallback(rwtMakeRunnableCallback(function));

class A {
  public:
    // Member function with one additional argument
    void bar(const RWRunnable&, RWExecutionState, int);
};

A a; // Instance of class A
// Create callback for A::bar() and register with runnable
rnb.addCallback(rwtMakeRunnableCallback(a,&A::bar,99);

// Create callback for function() and register with runnable
rnb.addCallback(rwtMakeRunnableCallbackG(function));

// Create callback for A::bar() and register with runnable
rnb.addCallback(rwtMakeRunnableCallbackMA1(A,a,&A::bar,int,99));

RWTFunctor2<const RWRunnable&,RWExecutionState>
rwtMakeRunnableCallback(void (*function)(const  RWRunnable&,
                       RWExecutionState))

Template function to create a runnable callback functor from a global function that takes a runnable reference and an execution state as arguments.

template <class A1, class AA1>
RWTFunctor2<const RWRunnable&,RWExecutionState>
rwtMakeRunnableCallback(void (*function)(const RWRunnable&,
                       RWExecutionState,A1), AA1 a1)

Template function to create a runnable callback functor from a global function that takes the runnable reference, the execution state, and one additional argument. a1 must be convertible to an instance of type A1.

template <class A1, class A2, class AA1, class AA2>
RWTFunctor2<const RWRunnable&,RWExecutionState>
rwtMakeRunnableCallback((void (*function) (const  RWRunnable&,
                       RWExecutionState,A1,A2), AA1 a1,AA2 a2)

Template function to create a runnable callback functor from a global function that takes the runnable reference, the execution state, and two additional arguments. a1 and a2 must be convertible to instances of types A1 and A2 respectively.

template <class Callee>
RWTFunctor2<const RWRunnable&,RWExecutionState>
rwtMakeRunnableCallback(Callee& callee,void
     (Callee::*function)(const RWRunnable&,RWExecutionState))

Template function to create a runnable callback functor from a member function that takes a runnable reference and an execution state as arguments.

template <class Callee, class A1, class AA1>
RWTFunctor2<const RWRunnable&,RWExecutionState>
rwtMakeRunnableCallback(Callee& callee,
      void (Callee::*function)
      (const RWRunnable&,RWExecutionState,A1), AA1 a1)

Template function to create a runnable callback functor from a global function that takes the runnable reference, the execution state, and one additional argument. a1 must be convertible to an instance of A1.

template <class Callee, class A1, class A2, 
          class AA1, class AA2>
RWTFunctor2<const RWRunnable&,RWExecutionState>
rwtMakeRunnableCallback(Callee& callee,
  void (Callee::*function)
 (const RWRunnable&,RWExecutionState,A1,A2), AA1 a1, AA2 a2)

Template function to create a runnable callback functor from a global function that takes the runnable reference, the execution state, and two additional arguments. a1 and a2 must be convertible to instances of types A1 and A2 respectively.

The macros in this section use the following naming conventions for the macro arguments:

function	Global function pointer.
A1	Type name of the first argument.
a1	Expression that can be converted to an instance of A1.
A2	Type name of the second argument.
a2	Expression that can be converted to an instance of A2.

The macros in this section use the following naming conventions for the macro arguments:

Callee	Type name of the function's class.
callee	Expression that results in a reference to a Callee instance.
function	Pointer to member function of class Callee
A1	Type name of the first argument.
a1	Expression that can be converted to an instance of A1.
A2	Type name of the second argument.
a2	Expression that can be converted to an instance of A2.
