36 /*!\class DESTRUCTEUR_GENERIQUE_
40 * The DESTRUCTEUR_GENERIQUE_ abstract class describes the comportement of any destruction object.
41 * Tis type is used to create a list of miscellaneous destruction object.
45 * The only way to use the DESTRUCTEUR_GENERIQUE_ class is inheritance :
46 * class DESTRUCTEUR_SPECIFIQUE_ : public DESTRUCTEUR_GENERIQUE_
48 * <B>Design description</B>
50 * A generic destructor supply two functionalities :
51 * -# a static method to add a destruction (objetct) to be performed DESTRUCTEUR_GENERIQUE_::Ajout(
52 * DESTRUCTEUR_GENERIQUE_ &objet) ;
53 * The Destruction object is stored in a list of pointer to DESTRUCTEUR_GENERIQUE_ objects.
54 * -# an object method to execute the destruction : operator()().
57 class DESTRUCTEUR_GENERIQUE_
60 static std::list<DESTRUCTEUR_GENERIQUE_*> *Destructeurs;
62 virtual ~DESTRUCTEUR_GENERIQUE_() {}//!< virtual destructor
63 static const int Ajout( DESTRUCTEUR_GENERIQUE_ &objet );//!< adds a destruction object to the list of destructions
64 virtual void operator()( void )=0 ;//!< performs the destruction
68 /*!\class DESTRUCTEUR_DE_
72 * The DESTRUCTEUR_DE_ class allows the user to program - at any moment - the destruction of an object
73 * at the end of the process.
77 * In this example the POINT_ ptrPoint will be destroyed at the end of the process (atexit).
79 * POINT_ *ptrPoint = new POINT_ ;<BR>
80 * DESTRUCTEUR_DE_<POINT_> *ptrDestruction = new DESTRUCTEUR_DE_<POINT_>( *ptrPoint ) ;
82 * Note that neither ptrPoint, nor ptrDestruction should be destroyed by the user.
84 * <B>Design description</B>
86 * The destruction object must be created dynamicaly because it suscribes himself in the list of
87 * destruction to be performed at the end of the process.
