I am trying to find a simple and efficient way to (de)serialize enums in Scala 3 using circe
.
Consider the following example:

QUESTION
Java's ArrayList
uses custom serialization and explicitly writes the size
. Nevertheless, size is not marked in ArrayList
as transient
. Why is size written two times: once via defaultWriteObject
and again vis writeInt(size)
as shown below (writeObject
method)?
ANSWER
Answered 2022-Mar-14 at 21:59It exists solely for compatibility with old java versions.
detailsIf you take a look at the comment above s.writeInt(size)
, you can see that this is supposed to be the capacity. In previous java versions, the serialized form of ArrayList
had a size and a capacity.
Both of them represent actual properties of an ArrayList
. The size
represents the number of items in the ArrayList
while the capacity
refers to the number of of possible items (length of the array) in it without the array needing to be recreated.
If you take a look at readObject
, you can see that the capacity is ignored:
QUESTION
I have a problem with Object-Oriented Project Hangman - serialization part. I saved my code in serialize method, but when I try to unserialize it, I have a problem with it. I see all components of classes in the YAML file and when I try to reach them with code, I can't do it. I don't know where the problem is. Here is my serialize method and deserialize method.
...ANSWER
Answered 2022-Feb-20 at 14:15I think it's actually working fine.
YAML.load
returns an different instance of Game. You can call methods on that instance, but you don't have any access to the properties.
QUESTION
I've attached the boost sample serialization code below. I see that they create an output archive and then write the class to the output archive. Then later, they create an input archive and read from the input archive into a new class instance. My question is, how does the input archive know which output archive its reading data from? For example, say I have multiple output archives. How does the input archive that is created know which output archive to read from? I'm not understanding how this is working. Thanks for your help!
...ANSWER
Answered 2022-Feb-13 at 16:00Like others said, you can set up a stream from existing content. That can be from memory (say istringstream
) or from a file (say ifstream
).
All that matters is what content you stream from. Here's you first example modified to save 10 different streams, which can be read back in any order, or not at all:
QUESTION
I have one call that return different objects name, in this case, each name is the hash of your wallet address, but I would like to treat them indifferently because all that matters is the data that is inside them, using a standard converter like Gson I am not able to do this, is there any way to do it manually?
...ANSWER
Answered 2022-Jan-25 at 12:34As I understand your question, this is less to do with retrofit and more with JSON parsing. Because the payload structure is a bit awkward I suggest you consume it in two steps:
- step 1. Consume the
content
success
,cache_last_updated
andtotal
- step 2. Add the
id

Is there a way to generate a nested JavaScript Object
from entries?
Object.fromEntries()
doesn't quite do it since it doesn't do nested objects.

QUESTION
I have an enum that I'd like to deserialize from JSON using kotlinx.serialization while ignoring unknown values. This is the enum

Answered 2021-Sep-24 at 12:41For now I think that the only way would be to use coerceInputValues
option with default value of enum field to be null like in this example:
QUESTION
I am using SharpSerializer to serialize/deserialize object.
I want the ability to ignore specific properties when deserializing.
SharpSerializer has an option to ignore properties by attribute or by classes and property name:
...ANSWER
Answered 2021-Nov-10 at 17:43You are correct that SharpSerializer does not implement ignoring of property values when deserializing. This can be verified from the reference source for ObjectFactory.fillProperties(object obj, IEnumerable properties)

QUESTION
I have a manytomany relation mapped with a custom table to add an extra column. I can deserialize it, but deserialized it shows the elements of the join table, I would to just the joined element. So what I currently get is the following:
...ANSWER
Answered 2021-Aug-18 at 01:35It seems like you would like an array of numbers being returned to the client.
You could create a getter that returns the array of ids and turn the other relationship as not serializable via annotations.
The fact that you only need one of the ids might be an indication of non ideal mapping in the database.

Install Biser
Grab from NuGet Biser (or DBreeze that contains Biser), grab from Nuget BiserObjectify.
Let’s assume you have several objects to serialize. It is necessary to prepare them:
Copy generated files into your project and embed/link them to the project. Try to recompile.
Probably, it will be necessary to add “partial” keyword to objects that must be serialized:
Remove BiserObjectify from your project, it will not be necessary until next time. Usage:
To have consistent data, after first serialization and storing byte[] into database - never delete serialized object/class properties.
To have consistent data, after first serialization and storing byte[] into database - add new properties only to the end of the object/class, after all other properties are listed.
JSON serializer can also store multi-dimensional arrays like [,,] [,] [,,,] etc., representing it as a Tuple<List , object itself> where Item1 represents array dimensions.
