Using a class in a static arrayed list C# - list

Here is what i would want to accomplish - i want this class globally accessible, and i need 6 instances of it. So basically it should be something like List[6] which would be initalized in a public static class...
class HH
{
public string hand { get; set; }
public string user { get; set; }
public int z { get; set; }
public int bb { get; set; }
public int eff { get; set; }
public int pos { get; set; }
public string pre { get; set; }
public string f { get; set; }
public string t { get; set; }
public string r { get; set; }
}
public static class tx
{
public static List<HH>[] HH = new List<HH>[6];
}
Now obv. this is wrong - but maybe you get the idea what i try to accomplish. Could someone give me an idea how i can accomplish that so that in my code i can access the elements of the class and read and write from and to it?

"public static List[] HH = new List[6];"
I think this is not enough. You only initialized the array, but HH objects left. After that code, you may write a loop to instantiate every HH object.
I hope that would be helpful. But if not, it may be great if you can provide more detail.
:)

You can do something like this:
public static class TX
{
public static List<HH> _HH { get; private set; }
static TX()
{
_HH = new List<HH>()
{
new HH(), new HH(), new HH(),
new HH(), new HH(), new HH()
};
}
internal class HH
{
public string hand { get; set; }
public string user { get; set; }
public int z { get; set; }
public int bb { get; set; }
public int eff { get; set; }
public int pos { get; set; }
public string pre { get; set; }
public string f { get; set; }
public string t { get; set; }
public string r { get; set; }
}
}
And use it like :
var hand = TX._HH[0].hand;

How to process "data" part of GCP PubSub message into a HashMap?

I'm getting pubsub message as below :
{
"data": {
"systemId": "system-1",
"userId": "userId-1",
"departmentId": "090",
"enrolmentDateTime": "2022-08-19T15:44:29.080Z",
"event_type": "REGISTRATION"
}
}
I want to further process this message in my springboot application based on the "event_type".
How can I just fetch "event_type" from this message and use it for comparison?
Any suggestions?
For eg I want to have processing like this :
if(event_type.equals("REGISTRATION")) { registrationHandler.handle(message); else { }
I have tried converting a PubSubMessage into string and then further map it to HashMap using ObjectMapper, but that gives me "data" as key and rest of the json part as a value.
public void process(final PubsubMessage message) throws ConsumerException {
String data = message.getData().toStringUtf8();
try {
ObjectMapper mapper = new ObjectMapper();
HashMap<String, String> dataMap = mapper.readValue(data, HashMap.class);
} ....
Instead of using a Map, you can use a typed object, example :
PubSubData.java file :
public class PubSubData {
private String systemId;
private String userId;
private String departmentId;
private String enrolmentDateTime;
private String event_type;
public PubSubData() {
}
public String getSystemId() {
return systemId;
}
public void setSystemId(String systemId) {
this.systemId = systemId;
}
public String getUserId() {
return userId;
}
public void setUserId(String userId) {
this.userId = userId;
}
public String getDepartmentId() {
return departmentId;
}
public void setDepartmentId(String departmentId) {
this.departmentId = departmentId;
}
public String getEnrolmentDateTime() {
return enrolmentDateTime;
}
public void setEnrolmentDateTime(String enrolmentDateTime) {
this.enrolmentDateTime = enrolmentDateTime;
}
public String getEvent_type() {
return event_type;
}
public void setEvent_type(String event_type) {
this.event_type = event_type;
}
}
PubSubResult.java file :
public class PubSubResult {
private PubSubData data;
public PubSubResult() {
}
public PubSubData getData() {
return data;
}
public void setData(PubSubData data) {
this.data = data;
}
}
Example of an unit test that deserializes data from PubsubMessage to the PubSubResult object :
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.google.protobuf.ByteString;
import com.google.pubsub.v1.PubsubMessage;
import org.junit.Test;
public class MyTest {
private static final ObjectMapper OBJECT_MAPPER;
static {
final ObjectMapper mapper = new ObjectMapper();
mapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
mapper.configure(DeserializationFeature.ADJUST_DATES_TO_CONTEXT_TIME_ZONE, false);
OBJECT_MAPPER = mapper;
}
#Test
public void testDeserializePubSubData() {
final String data = "{\n" +
" \"data\": {\n" +
" \"systemId\": \"system-1\",\n" +
" \"userId\": \"userId-1\",\n" +
" \"departmentId\": \"090\",\n" +
" \"enrolmentDateTime\": \"2022-08-19T15:44:29.080Z\",\n" +
" \"event_type\": \"REGISTRATION\"\n" +
" }\n" +
"}";
final PubsubMessage message = PubsubMessage.newBuilder()
.setData(ByteString.copyFrom(data.getBytes()))
.build();
final String dataResult = message.getData().toStringUtf8();
final PubSubResult resultData = deserialize(dataResult);
// Access to the event type.
final String eventType = resultData.getData().getEvent_type();
}
private PubSubResult deserialize(final String value) {
try {
return OBJECT_MAPPER.readValue(value, PubSubResult.class);
} catch (JsonProcessingException e) {
throw new IllegalStateException("Error !!", e);
}
}
}

Sitecore MVC model lost after postback

I have a page /registration that contains two forms on it.
One for registration and one for logging in. The registration form is one controller rendering, the login form is another controller rendering.
When I load /registration the page loads correctly and the model is populated.
When I click the submit button, the Post action fires and the model is suddenly reset back to it's default state. Shouldn't the model remain populated without having to repopulate it?

There is currently a problem with Sitecore MVC and having multiple forms. I believe the problem is that you have [HttpGet] set to your Index action which might mess the Sitecore Routing. You can check for more problems with multiple forms in this blog post.

Having a composition relationship in ASP .NET?

I have a Car composed by a Driver. I have problems showing either informations on the gridview. It's only shows Car's info. on the gridview, and I wanna display like: Car: Lancia Driver: Sandro, something like that.
Here's the code:
Car:
[Serializable]
public class Car
{
public String Brand { get; set; }
public String Model { get; set; }
public int Year { get; set; }
public Driver Driver { get; set; }
public Car(String Brand, String Model, int Year, Driver Driver)

Brand = Brand;
Model = Model;
Year = Year;
Driver = Driver;
}
public Car()

Error on Spring REST webservice call

I have following webservice call
#RequestMapping(value = "modifyUser/{userDn}", method = RequestMethod.POST, headers="Accept=application/json")
public #ResponseBody
JSONObject modifyUser(#PathVariable String userDn, #RequestBody DirectoryUser directoryUser) {
// Modify User
boolean modifiedUser = this.authenticationService.modifyUser(userDn, directoryUser.getPassword(), directoryUser);
// Build JSONObject
JSONObject jsonObject = new JSONObject();
jsonObject.put("modifyUser", modifiedUser);
return jsonObject;
}
I am using following client method to access above REST webservice.
String url = "http://www.local.com:8080/CommonAuth-1.0-SNAPSHOT/api/authentication/modifyUser/";

HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
I always get "The server refused this request because the request entity is in a format not supported by the requested resource for the requested method" error. What is wrong in my code. I am able to access other webservice calls without using #RequestBody and using simple path variables. The issue is with #RequestBody and how i am using HttpPost.

Can you check what the status code says? Also, please check if it is HTTPS.
By default Spring try to use Jackson for json marshall/unmarshall:
private static final boolean jackson2Present =
ClassUtils.isPresent("com.fasterxml.jackson.databind.ObjectMapper", WebMvcConfigurationSupport.class.getClassLoader()) &&
ClassUtils.isPresent("com.fasterxml.jackson.core.JsonGenerator", WebMvcConfigurationSupport.class.getClassLoader());
you need to add Jackson libs to your project.

I don't have any problem in serialization. But for deserialize, it can just deserialize first object not all of them. What should I do, please help me!
From a separate email from the OP, the following methods were obtained (I've tidied them a little, not much):
static void Serialize(object obj, string filename)
{
using (FileStream streamOut = new FileStream(filename, FileMode.Append))
{
BinaryFormatter formatter = new BinaryFormatter();
formatter.Serialize(streamOut, obj);
}
}
public static List<Section> DeserializeList(string filename)
{
using (FileStream streamIn = File.OpenRead(filename))
{
BinaryFormatter formatter = new BinaryFormatter();
return (List<Section>) formatter.Deserialize(streamIn);
}
}
The key observation here is that it is assuming that BinaryFormatter is an appendable format, and that serializing two objects sequentially is the same as serializing 2 items at the same time (a list), for example:
if(File.Exists("foo.bin")) File.Delete("foo.bin"); // start afresh
Serialize(new Section { Diameter = 1.2, ClearCover = 3.4 }, "foo.bin");
Serialize(new Section { Diameter = 5.6, ClearCover = 7.8 }, "foo.bin");
var clone = DeserializeList("foo.bin");
However, that simply is not the case. To deserialize the items in this way, we would have to do something like:
public static List<Section> DeserializeList(string filename)
{
using (FileStream streamIn = File.OpenRead(filename))
{
List<Section> list = new List<Section>();
BinaryFormatter formatter = new BinaryFormatter();
while(streamIn.Position != streamIn.Length)
{
list.Add((Section) formatter.Deserialize(streamIn));
}
return list;
}
}
which it a little vexing - not least because it can't be applied to all streams (.Length and even .Position are not universally available).
The above should work, but I would strongly advise using an appendable format, such as protobuf. In fact, protobuf-net makes this scenario effortless, both in terms of the model:
[ProtoContract]
public class Section
{
[ProtoMember(1)] public double ClearCover { get; set; }
[ProtoMember(2)] public string SectionName { get; set; }
[ProtoMember(3)] public double Diameter { get; set; }
[ProtoMember(4)] public double Height { get; set; }
[ProtoMember(5)] public double Width { get; set; }
[ProtoMember(6)] public double InternalDiameter { get; set; }
[ProtoMember(7)] public double ExternalDiameter { get; set; }
[ProtoMember(8)] public double InternalHeight { get; set; }
[ProtoMember(9)] public double ExternalHeight { get; set; }
[ProtoMember(10)] public double InternalWidth { get; set; }
[ProtoMember(11)] public double ExternalWidth { get; set; }
[ProtoMember(12)] public double FlangeWidth { get; set; }
[ProtoMember(13)] public double FlangeThickness { get; set; }
[ProtoMember(14)] public double WebWidth { get; set; }
}
and the serialization / deserialization:
static void Main()
{
if (File.Exists("foo.bin")) File.Delete("foo.bin"); // start afresh
Serialize(new Section { Diameter = 1.2, ClearCover = 3.4 }, "foo.bin");
Serialize(new Section { Diameter = 5.6, ClearCover = 7.8 }, "foo.bin");
var clone = DeserializeList("foo.bin");
}
static void Serialize(object obj, string filename)
{
using (FileStream streamOut = new FileStream(filename, FileMode.Append))
{
Serializer.NonGeneric.SerializeWithLengthPrefix(
streamOut, obj, PrefixStyle.Base128, Serializer.ListItemTag);
}
}
public static List<Section> DeserializeList(string filename)
{
using (FileStream streamIn = File.OpenRead(filename))
{
return Serializer.DeserializeItems<Section>(
streamIn, PrefixStyle.Base128, Serializer.ListItemTag).ToList();
}
}
Finally, the BinaryFormatter data for those 2 rows was 750 bytes; with protobuf-net: 40 bytes.
