Detailed Description

template<class S1>
class RWTFunctorList1< S1 >

Deprecated

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

The RWTFunctorList1 class is a sequence of functors whose invocation takes one argument.

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/RWTFunctorList1.h>
#include <rw/functor/rwtMakeFunctor1.h>
#include <iostream>
 
void foo(int x, short y) {
  std::cout << "x is " << x << " and y is " << y << std::endl;
}
 
void bar(int a) { std::cout << "a is " << a << std::endl; }
 
int main() {
  // create new functors
  RWTFunctor1<int> fooFunctor =
      rwtMakeFunctor1((void (*)(int))0, foo, 6);
  RWTFunctor1<int> barFunctor = rwtMakeFunctor1((void (*)(int))0, bar);
 
  // create a new functor list
  RWTFunctorList1<int> 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);
 
  return 0;
}

OUTPUT:

x is 3 and y is 6
a is 3

Constructor & Destructor Documentation

RWTFunctorList1() [1/2]

template<class S1 >

RWTFunctorList1< S1 >::RWTFunctorList1

(

void

)

Constructs an empty list instance.

~RWTFunctorList1()

template<class S1 >

RWTFunctorList1< S1 >::~RWTFunctorList1 ( void )

inline

Destructor.

RWTFunctorList1() [2/2]

template<class S1 >

RWTFunctorList1< S1 >::RWTFunctorList1 ( const RWTFunctorList1< S1 > & second )

inline

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

Member Function Documentation

add()

template<class S1 >

void RWTFunctorList1< S1 >::add	(	const RWTFunctor1< S1 > &	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 >

void RWTFunctorList1< S1 >::operator()

(

S1

s1

)

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, the method throws an RWTHRInternalError exception.

operator=()

template<class S1 >

RWTFunctorList1< S1 > & RWTFunctorList1< S1 >::operator= ( const RWTFunctorList1< S1 > & second )

inline

Assignment operator. Binds this list instance to another list's representation.

remove()

template<class S1 >

void RWTFunctorList1< S1 >::remove

(

const RWTFunctor1< S1 > &

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 >

void RWTFunctorList1< S1 >::update

(

void

)

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