Tengo esta excepción y no entiendo por qué se lanzaría o cómo debería manejarla.
try {
os.writeObject(element);
} catch (IOException e) {
e.printStackTrace();
}
Donde element
es un que TransformGroup
contiene alguna otra TransformGroups
instancia de la clase Atom:
public class Atom extends Group implements Serializable{
float pozX,pozY;
Group group= new Group();
Color3f blue = new Color3f(new Color(255));
Color3f black = new Color3f(new Color(0));
Sphere AtSph=new Sphere();
public Atom(final float WEIGHT, final int BOUNDS,final float radius,Color3f color)
{
AppSetting ap= new AppSetting(color, black);
AtSph=new Sphere(radius,1,100,ap);
}
}

javax.media.j3d.TransformGroup
sí mismo no implementa SerializableAtom
ambos se extiendenGroup
y tienen unGroup
miembro?Respuestas:
Los campos de su objeto tienen a su vez sus campos, algunos de los cuales no se implementan
Serializable
. En su caso, la clase infractora esTransformGroup
. ¿Cómo resolverlo?Serializable
transient
fuente
Serializable
y usareadObject()
ywriteObject()
serializa manualmente los datos de la clase de terceros. En algunos casos, este podría ser un enfoque razonable. stackoverflow.com/a/12963580/1208581java.io.NotSerializableException
puede ocurrir cuando serializa una instancia de clase interna porque:Ref: La interfaz serializable
fuente
Haga que la clase sea serializable implementando la interfaz
java.io.Serializable
.java.io.Serializable
- Interfaz de marcador que no tiene ningún método.ObjectOutputStream
que este objeto es un objeto serializable.fuente
