Actually Im gettin quite blur with the shared object concept. This is my AS
file.
*
package* {
*import* mx.collections.ArrayCollection;
*import* flash.net.SharedObject;
*public* *class* LSOHandler {
*private* *var* mySO:SharedObject;
*private* *var* ac:ArrayCollection;
*private* *var* lsoType:String;
*// The parameter is "feeds" or "sites".
*
*public* *function* LSOHandler(s:String) {
init(s);
}
*private* *function* init(s:String):*void* {
ac = *new* ArrayCollection();
lsoType = s;
mySO = SharedObject.getLocal(lsoType);
*// mySO.clear();
*
*if* (getObjects()) {
ac = getObjects();
}
}
*public* *function* getObjects():ArrayCollection {
*return* mySO.data[lsoType];
}
*public* *function* addObject(o:Object):*void* {
ac.addItem(o);
updateSharedObjects();
}
*private* *function* updateSharedObjects():*void* {
mySO.data[lsoType] = ac;
mySO.flush();
}
}
}
Hope you can help me.
