Detailed Description

template<class S1, class S2>
class RWTFunctorList2< S1, S2 >

Deprecated

As of SourcePro 12.5, use RWTValSlist<RWTFunctor<void(S1, S2)>> instead.

The RWTFunctorList2 class is a sequence of functors whose invocation takes two arguments.

A function object, or a functor, encapsulates a call to an associated function. When a functor is invoked, it calls the associated function.

A functor list is a sequence of such functors. The list's invocation results in the invocation of all functors contained in the list. This is useful when you wish to connect more that one invocation to a particular action.

Example

#include <rw/functor/list/RWTFunctorList2.h>
#include <rw/functor/rwtMakeFunctor2.h>
#include <iostream>
 
void foo(int x, short y) {
  std::cout << "x is " << x << " and y is " << y << std::endl;
}
 
void bar(int a, short b) {
  std::cout << "a is " << a << " and b is " << b << std::endl;
}
 
int main() {
  // create new functors
  RWTFunctor2<int, short> fooFunctor =
      rwtMakeFunctor2((void (*)(int, short))0, foo);
  RWTFunctor2<int, short> barFunctor =
      rwtMakeFunctor2((void (*)(int, short))0, bar);
 
  // create a new functor list
  RWTFunctorList2<int, short> flist;
 
  // add the functors to the list
  flist.add(fooFunctor, RW_CALL_REPEATEDLY);
  flist.add(barFunctor, RW_CALL_REPEATEDLY);
 
  // invoke the list and see that both the functors are called
  flist(3, 45);
 
  return 0;
}

OUTPUT:

x is 3 and y is 45
a is 3 and b is 45

Constructor & Destructor Documentation

RWTFunctorList2() [1/2]

template<class S1 , class S2 >

RWTFunctorList2< S1, S2 >::RWTFunctorList2

(

void

)

Constructs an empty list instance.

RWTFunctorList2() [2/2]

template<class S1 , class S2 >

RWTFunctorList2< S1, S2 >::RWTFunctorList2 ( const RWTFunctorList2< S1, S2 > & second )

inline

Copy constructor. Creates a new list instance that shares its list representation with second.

~RWTFunctorList2()

template<class S1 , class S2 >

RWTFunctorList2< S1, S2 >::~RWTFunctorList2 ( void )

inline

Destructor.

Member Function Documentation

add()

template<class S1 , class S2 >

void RWTFunctorList2< S1, S2 >::add	(	const RWTFunctor2< S1, S2 > &	functor,
		RWCallbackScope	scope )

Adds the specified functor to the list. Duplicates are allowed, in which case the functor is run each time it appears.

The add request is stored until either the list is invoked, or the update() method is called.

operator()()

template<class S1 , class S2 >

void RWTFunctorList2< S1, S2 >::operator()	(	S1	s1,
		S2	s2 ) const

Invokes the functor list. This includes updating the list with any stored adds or removes, invoking each functor in the list, and removing any functors that were added with the RW_CALL_ONCE flag.

If more than one thread attempts to invoke the list at any one time, throws an RWTHRInternalError exception.

operator=()

template<class S1 , class S2 >

RWTFunctorList2< S1, S2 > & RWTFunctorList2< S1, S2 >::operator= ( const RWTFunctorList2< S1, S2 > & second )

inline

Assignment operator. Binds this list instance to representation of list second.

remove()

template<class S1 , class S2 >

void RWTFunctorList2< S1, S2 >::remove

(

const RWTFunctor2< S1, S2 > &

functor

)

Removes all entries from the list for the specified functor.

The remove request is stored until either the list is invoked, or the update() method is called.

update()

template<class S1 , class S2 >

void RWTFunctorList2< S1, S2 >::update

(

void

)

Updates the list with any add() or remove() requests that have occurred since the last invocation.
