I have Sample_Product__c custom object, and wanted to create object with relational field's external id:
final Map<String, Object> prod = new HashMap<String, Object>();
prod.put("External_ID__c", obj.getString("medicineName"));
final Map < String, Object > sample = new HashMap < String, Object > ();
sample.put("Product__r", prod);
sample.put("LotNumber__c", obj.getString("medicineSerialNo"));
sample.put("GivenDate__c", format.format(givenDate));
sample.put("ExpiredDate__c", format.format(expireDate));
sample.put("GivenNumber__c", obj.getString("medicineQuantity"));
sample.put("Call__c", callid);
RestRequest.getRequestForCreate(getString(R.string.api_version), "Sample_Product__c", sample);
This gives error as, Product__r should be SObject...
In PHP, I was doing this like so:
$sfobject = new stdclass();
$sfobject->External_ID__c = "...";
$sample->Product__r = $sfobject;
But have no idea how to achieve this with salesforce mobile SDK... hope someone knows, thanks!

I have complex classes like this:
abstract class Animal { ... }
class Dog: Animal{ ... }
class Cat: Animal{ ... }
class Farm{
public List<Animal> Animals {get;set;}
...
}
My goal is to send objects from computer A to computer B
I was able to achieve my goal by using BinaryFormatter serialization. It enabled me to serialize complex classes like Animal in order to transfer objects from computer A to computer B. Serialization was very fast and I only had to worry about placing a serializable attribute on top of my classes. But now BinaryFormatter is obsolete and if you read on the internet future versions of dotnet may remove that.
As a result I have these options:
Use System.Text.Json
This approach does not work well with polymorphism. In other words I cannot deserialize an array of cats and dogs. So I will try to avoid it.
Use protobuf
I do not want to create protobuf map files for every class. I have over 40 classes this is a lot of work. Or maybe there is a converter that I am not aware of? But still how will the converter be smart enough to know that my array of animals can have cats and dogs?
Use Newtonsoft (json.net)
I could use this solution and build something like this: https://stackoverflow.com/a/19308474/637142 . Or even better serialize the objects with a type like this: https://stackoverflow.com/a/71398251/637142. So this will probably be my to go option.
Use MongoDB.Bson.Serialization.BsonSerializer Because I am dealing with a lot of complex objects we are using MongoDB. MongoDB is able to store a Farm object easily. My goal is to retrieve objects from the database in binary format and send that binary data to another computer and use BsonSerializer to deserialize them back to objects.
Have computer B connect to the database remotely. I cannot use this option because one of our requirements is to do everything through an API. For security reasons we are not allowed to connect remotely to the database.
I am hopping I can use step 4. It will be the most efficient because we are already using MongoDB. If we use step 3 which will work we are doing extra steps. We do not need the data in json format. Why not just sent it in binary and deserialize it once it is received by computer B? MongoDB.Driver is already doing this. I wish I knew how it does it.
This is what I have worked so far:
MongoClient m = new MongoClient("mongodb://localhost:27017");
var db = m.GetDatabase("TestDatabase");
var collection = db.GetCollection<BsonDocument>("Farms");
// I have 1s and 0s in here.
var binaryData = collection.Find("{}").ToBson();
// this is not readable
var t = System.Text.Encoding.UTF8.GetString(binaryData);
Console.WriteLine(t);
// how can I convert those 0s and 1s to a Farm object?
var collection = db.GetCollection<RawBsonDocument>(nameof(this.Calls));
var sw = new Stopwatch();
var sb = new StringBuilder();
sw.Start();
// get items
IEnumerable<RawBsonDocument>? objects = collection.Find("{}").ToList();
sb.Append("TimeToObtainFromDb: ");
sb.AppendLine(sw.Elapsed.TotalMilliseconds.ToString());
sw.Restart();
var ms = new MemoryStream();
var largestSixe = 0;
// write data to memory stream for demo purposes. on real example I will write this to a tcpSocket
foreach (var item in objects)
{
var bsonType = item.BsonType;
// write object
var bytes = item.ToBson();
ushort sizeOfBytes = (ushort)bytes.Length;
if (bytes.Length > largestSixe)
largestSixe = bytes.Length;
var size = BitConverter.GetBytes(sizeOfBytes);
ms.Write(size);
ms.Write(bytes);
}
sb.Append("time to serialze into bson to memory: ");
sb.AppendLine(sw.Elapsed.TotalMilliseconds.ToString());
sw.Restart();
// now on the client side on computer B lets pretend we are deserializing the stream
ms.Position = 0;
var clones = new List<Call>();
byte[] sizeOfArray = new byte[2];
byte[] buffer = new byte[102400]; // make this large because if an document is larger than 102400 bytes it will fail!
while (true)
{
var i = ms.Read(sizeOfArray, 0, 2);
if (i < 1)
break;
var sizeOfBuffer = BitConverter.ToUInt16(sizeOfArray);
int position = 0;
while (position < sizeOfBuffer)
position = ms.Read(buffer, position, sizeOfBuffer - position);
//using var test = new RawBsonDocument(buffer);
using var test = new RawBsonDocumentWrapper(buffer , sizeOfBuffer);
var identityBson = test.ToBsonDocument();
var cc = BsonSerializer.Deserialize<Call>(identityBson);
clones.Add(cc);
}
sb.Append("time to deserialize from memory into clones: ");
sb.AppendLine(sw.Elapsed.TotalMilliseconds.ToString());
sw.Restart();
var serializedjs = new List<string>();
foreach(var item in clones)
{
var foo = item.SerializeToJsStandards();
if (foo.Contains("jaja"))
throw new Exception();
serializedjs.Add(foo);
}
sb.Append("time to serialze into js: ");
sb.AppendLine(sw.Elapsed.TotalMilliseconds.ToString());
sw.Restart();
foreach(var item in serializedjs)
{
try
{
var obj = item.DeserializeUsingJsStandards<Call>();
if (obj is null)
throw new Exception();
if (obj.IdAccount.Contains("jsfjklsdfl"))
throw new Exception();
}
catch(Exception ex)
{
Console.WriteLine(ex);
throw;
}
}
sb.Append("time to deserialize js: ");
sb.AppendLine(sw.Elapsed.TotalMilliseconds.ToString());
sw.Restart();
Using Hapi Fhir, I try to write a query to use a map to pass in where condition, as follow:
Map<String, List<IQueryParameterType>> hmParameter = criteria.getMapForWhere();
Bundle bundle = fhirClientR4Configuration.clientFhihrR4().search().forResource(ServiceRequest.class)
.where(hmParameter).returnBundle(Bundle.class).execute();
My criteria object has a method getMapForWhere() where I populate this map with information inside my wrapper front end object as follow:
public Map<String, List<IQueryParameterType>> getMapForWhere() {
Map<String, List<IQueryParameterType>> hmOut = new HashMap<String, List<IQueryParameterType>>();
// Adding STATUS
if (this.status != null && !this.status.equals("")) {
StringParam sp = new StringParam();
sp.setValue(this.status);
List<IQueryParameterType> lst = new ArrayList<IQueryParameterType>();
lst.add(sp);
hmOut.put(ServiceRequest.SP_STATUS, lst);
}
// Adding INTENT
if (this.intent != null && !this.intent.equals("")) {
StringParam sp = new StringParam();
sp.setValue(this.intent);
List<IQueryParameterType> lst = new ArrayList<IQueryParameterType>();
lst.add(sp);
hmOut.put(ServiceRequest.SP_INTENT, lst);
}
return hmOut;
}
This code works fine when I want to wirte a query with all AND.
But if I want to add another condition as follow:
List<IQueryParameterOr> lstOr = new ArrayList<IQueryParameterOr>();
StringOrListParam lstServices = new StringOrListParam();
StringParam sp = new StringParam();
StringParam sg = new StringParam();
sp.setValue(MEDICAL_SERVICE_PAI);
sg.setValue(SOCIAL_SERVICE_PAI);
lstServices.addOr(sp);
lstServices.addOr(sg);
lstOr.add(lstServices);
hmOut.put(ServiceRequest.SP_CATEGORY, lstOr);
Obviously hmOut goes in error because definition of that map is different. But I don't know how to convert IParameterOr with IParameterType.
I need to translate this code from lucene.net 2.3.2 to 3.0.3.
This code works fine in 2.3.2 but in 3.0.3 the method tokenStream.Next() does not return a token but a boolean. What I need to understand is where to read the token object when next() returns true.
Analyzer analyzer = new StandardAnalyzer();
StringReader stringReader = new StringReader("the house id red");
TokenStream tokenStream = analyzer.TokenStream("", stringReader);
Token token = tokenStream.Next();
while (token != null)
{
System.Diagnostics.Debug.Write(token.TermText());
token = tokenStream.Next();
}
The TokenStreams in Lucene 3+ can now represent a whole set of values (called attributes) for each position in the stream. So you need to modify your example to be attribute aware...
var analyzer = new StandardAnalyzer(Lucene.Net.Util.Version.LUCENE_30);
var stringReader = new StringReader("the house id red");
var tokenStream = analyzer.TokenStream(string.Empty, stringReader);
var termAtt = tokenStream.GetAttribute<ITermAttribute>();
while (tokenStream.IncrementToken())
{
Console.WriteLine(termAtt.Term);
}
I would like to code using normal early binding datatypes rather than using dynamic (or var). However in order to enumerate using
foreach (var item in fbFeed.data)
requires that fbFeed is a type which has a property 'data'
var fb = new Facebook.FacebookClient(longlifeaccess_token);
dynamic fbFeed = fb.Get("me/feed");
foreach (var item in fbFeed.data)
{
var thepost = (IDictionary<string, object>)item;
Console.WriteLine("ID {0}", thepost["id"].ToString());
}
What data types should I be using for fbFeed and item in the above code, if I do not want to use var or dynamic.
I think this should be close
Facebook.FacebookClient fb = new Facebook.FacebookClient(longlifeaccess_token);
Facebook.JsonObject feFeed = (Facebook.JsonObject)fb.Get("me/feed");
Facebook.JsonArray feFeedData = (Facebook.JsonArray)feFeed["data"];
foreach (Facebook.JsonObject item in feFeedData)
{
IDictionary<string, object> post = (IDictionary<string, object>)item;

I have to created a dynamic URLcontaining the user id and email parameters, which will direct to sign up form in my GWT application. I want to set and get the parameters in the query string. I have referred tp http://code.google.com/p/gwt-examples/source/browse/trunk/System/src/com/gawkat/gwt/system/client/global/QueryString.java?r=1241 but here QueryStringData is inaccessible to my project.Please tell me how I can do it? Any alternative could also help me.
#Stein, but there is (a query parameter tokenizer in GWT): e.g. Window.Location.getParameter("debug") will return the string value of the parameter debug.
Don't think there's a simple tokenized query string parser in GWT. But you can get the raw query string by using:
String queryString = Window.Location.getQueryString();
Parse it any way you like. I use it like this to set debug flags etc.:
boolean debugMode = Window.Location.getQueryString().indexOf("debug=true") >= 0;
Note that changing values in the query part of the url (between the ? and the #) will reload the page. While changing the "hash part" of the url (anything after the #) will not reload the page. Which is why the com.google.gwt.user.client.History uses the hash part.
If you want really want to parse the history token (hash part) to encode parameters, here's the code for that:
private static Map<String, String> buildHashParameterMap() {
final String historyToken = History.getToken();
Map<String, String> paramMap = new HashMap<String, String>();
if (historyToken != null && historyToken.length() > 1) {
for (String kvPair : historyToken.split("&")) {
String[] kv = kvPair.split("=", 2);
if (kv.length > 1) {
paramMap.put(kv[0], URL.decodeQueryString(kv[1]));
} else {
paramMap.put(kv[0], "");
}
}
}
return paramMap;
}
There is in-built support for getting all of the parameters.
Simply call:
Map<String, List<String>> parameterMap = Window.Location.getParameterMap();
