Ok so I am reading what has already been asking about NPE on here but I can't seem to find anything that will help with my code. It says that It is being thrown at .searchCollection(COLLECTION_NAME).
public class PantryDataStorage {
private static final String COLLECTION_NAME = "pantry";
private static HashMap<String, PantryItem> pantry = getDatabaseItems();
private static String API_KEY = "c3672b0c-b96c-4145-8b75-bd6895b5458e";
private static OrchestrateClient client = new OrchestrateClient(API_KEY);
ShoppingItem shoppingItem = new ShoppingItem();
public static void savePantryItem(String itemName, PantryItem updatedPantryItem){
pantry.put(itemName, updatedPantryItem);
client.kv(COLLECTION_NAME, itemName).put(updatedPantryItem).get().getKey();
}
public static void deletePantryItem(String itemName){
pantry.remove(itemName);
client.kv(COLLECTION_NAME, itemName)
.delete()
.get();
}
public static HashMap<String, PantryItem>getDatabaseItems(){
SearchResults<PantryItem> result = client
.searchCollection(COLLECTION_NAME)
.limit(100)
.get(PantryItem.class, "*")
.get();
Iterator<Result<PantryItem>> iterator = result.getResults().iterator();
HashMap<String, PantryItem> listHash = new HashMap<String, PantryItem>();
while(iterator.hasNext()){
PantryItem pantryitem = iterator.next().getKvObject().getValue();
listHash.put(pantryitem.getItemName(), pantryitem);
}
return listHash;
}
public static boolean itemConsists(String itemName){
pantry.containsKey(itemName);
return true;
}
public static void iteratorMethod(){
Iterator<PantryItem> pantryItemIterator = pantry.values().iterator();
while (pantryItemIterator.hasNext()) {
System.out.println(pantryItemIterator.next());
}
}
}
