problème d'un vecteur de vecteur
Bonjour,
j'ai une file d'attente qui s'applle mysession.getSampleSet qui est constitué de
d'échantillons de type TspSample.
sample_info de type Vector<Object> est un vecteur constitué de 4 composantes (int, String, Object, int)
data est un vecteur dont les composantes sont de type Vector<Object>

| public Vector<Vector> getData(){
Vector<Vector> data = new Vector<Vector>();
Vector<Object> sample_info = new Vector<Object>();
TspSample sample = null;
for (int i=0; i<needed_ID.size();i++){
sample = mySession.getSampleSet().getSample();
sample_info.add(0,sample.getPgi());
sample_info.add(1,TspSSIArray[i].name);
sample_info.add(2,sample.getValue());
sample_info.add(3,sample.getTimeStamp());
data.addElement(sample_info);
System.out.println("Sample <"
+ i
+ "> = { provider_global_index ="
+ data.get(i).get(0)
+", name = "
+ data.get(i).get(1)
+ ", value ="
+ data.get(i).get(2)
+ ", time_stamp ="
+ data.get(i).get(3)
+"}"
);
if (i>1){
int p=i-2;
System.out.println("Sample <"
+ p
+ "> = { provider_global_index ="
+ data.get(p).get(0)
+", name = "
+ data.get(p).get(1)
+ ", value ="
+ data.get(p).get(2)
+ ", time_stamp ="
+ data.get(p).get(3)
+"}"
);
int o=i-1;
System.out.println("Sample <"
+ o
+ "> = { provider_global_index ="
+ data.get(o).get(0)
+", name = "
+ data.get(o).get(1)
+ ", value ="
+ data.get(o).get(2)
+ ", time_stamp ="
+ data.get(o).get(3)
+"}"
);
}
System.out.println("-------------------------");
return data;
} |
mon problème c'est que data finalement est constitué de 4 vecteurs identiques qui est le dernier vecteur ajouté.
Résultat :
Code:
1

merci pour l'aide
