example I want to translate the pattern memnto (from aspectj) to jboss aop
package MEMENTO;
|
| public class Initiateur {
|
| protected int valeur = 0;
|
| public void incrementation() {
| valeur++;
| }
|
| public void affichage() {
| System.out.println("La valeur courante est : " + valeur);
| }
|
|
| public void setMemento(InitiateurI o, Memento m){}
| }
package MEMENTO;
|
| public class Initiateur1Memento implements InitiateurI{
|
|
|
| public Initiateur1Memento (){
|
| }
|
| public Memento createMementoFor(InitiateurI o) {
| if (o instanceof Initiateur) {
| Memento m = new Memento() {
| private Integer state;
|
| public void setetat(Integer state) {
| this.state = (Integer) state;
| }
|
| public int getState(){
| return state;
| }
| };
| m.setetat(new Integer(((Initiateur)o).valeur));
| return m;
| }
| else {
| throw new MementoException("Initialisateur invalide");
| }
| }
|
| public void setMemento(InitiateurI o, Memento m) {
| if (o instanceof Initiateur) {
| Integer integer = (Integer) m.getState();
| ((Initiateur)o).valeur = integer.intValue();
| } else {
| throw new MementoException("Initialisateur invalide");
| }
| }
| }
|
package MEMENTO;
|
| public interface InitiateurI {
| public Memento createMementoFor(InitiateurI o);
|
| public void setMemento(InitiateurI o, Memento m);
| }
package MEMENTO;
|
| public interface Memento {
| public void setetat(Integer state);
| public int getState();

public class Main {
|
|
| public static void main(String[] args) {
|
| Memento memento1 = null;
| Initiateur initiateur = new Initiateur();
|
| for (int i=1; i<=5; i++) {
| if (i==1){memento1=
Initiateur1Memento.createMementoFor(initiateur);}
| else {memento1.setetat(initiateur.valeur);}
|
| initiateur.incrementation();
| initiateur.affichage();
|
| }
| System.out.println("");
| System.out.println(" <- annuler");
| Initiateur1Memento.setMemento(initiateur, memento1);

eclipse tells me 2 error in the Main
line 14 "The method createMementoFor(InitiateurI) in the type
Initiateur1Memento is not applicable for the arguments (Initiateur)"
line23 "The method setMemento(InitiateurI, Memento) in the type
