Jackson Annotations: Difference Between JsonIgnoreProperties(ignoreUnknown=true) and JsonInclude(Include.NON_EMPTY)
Short answer: @JsonIgnoreProperties(ignoreUnknown=true) is applicable at deserialization of JSON to Java object (POJO) only. If your POJO does not contain certain properties that JSON does contain, they are ignored and no error is thrown. On the other hand @JsonInclude(Include.NON_EMPTY) is used at serialization of POJO to JSON and it says, skip POJO properties that are: … Read more
SerializationException: type not included in serializable type set
GWT keeps track of a set of types which can be serialized and sent to the client. your.class.Type apparently was not on this list. Lists like this are stored in .gwt.rpc files. These lists are generated, so editing these lists is probably useless. How these lists are generated is a bit unclear, but you can … Read more
Serializing groovy map to string with quotes
Groovy provides the inspect() method returns an object as a parseable string: // serialize def m = [a: 123, b: ‘test’] def str = m.inspect() // deserialize m = Eval.me(str) Another way to serialize a groovy map as a readable string is with JSON: // serialize import groovy.json.JsonBuilder def m = [a: 123, b: ‘test’] … Read more
How to Serialize Binary Tree
All those articles talk mostly about the serialization part. The deserialization part is slightly tricky to do in one pass. I have implemented an efficient solution for deserialization too. Problem: Serialize and Deserialize a binary tree containing positive numbers. Serialization part: Use 0 to represent null. Serialize to list of integers using preorder traversal. Deserialization … Read more
How to serialize a graph structure?
How do you represent your graph in memory? Basically you have two (good) options: an adjacency list representation an adjacency matrix representation in which the adjacency list representation is best used for a sparse graph, and a matrix representation for the dense graphs. If you used suchs representations then you could serialize those representations instead. … Read more
Does protobuf-net have built-in compression for serialization?
No it does not; there is no “compression” as such specified in the protobuf spec; however, it does (by default) use “varint encoding” – a variable-length encoding for integer data that means small values use less space; so 0-127 take 1 byte plus the header. Note that varint by itself goes pretty loopy for negative … Read more
SignalR : use camel case
Roll your own Conttract resolver like public class SignalRContractResolver : IContractResolver { private readonly Assembly assembly; private readonly IContractResolver camelCaseContractResolver; private readonly IContractResolver defaultContractSerializer; public SignalRContractResolver() { defaultContractSerializer = new DefaultContractResolver(); camelCaseContractResolver = new CamelCasePropertyNamesContractResolver(); assembly = typeof(Connection).Assembly; } public JsonContract ResolveContract(Type type) { if (type.Assembly.Equals(assembly)) { return defaultContractSerializer.ResolveContract(type); } return camelCaseContractResolver.ResolveContract(type); } } Register … Read more
Difference between Microsoft’s Bond and Google’s Protocol Buffers [closed]
In general, Bond has better type system and supports multiple protocols. In particular, pros are: Bond supports generics Bond has different types to represent collections: vector<T>, map<T>, list<T> Bond supports type-safe lazy deserialization (bonded<T>) Bond supports multiple formats (fast binary, compact binary, XML, JSON) + marshaling and transcoding Cons: Bond doesn’t support different types for … Read more
Deserialization of reference types without parameterless constructor is not supported
You can achieve your desired result. You need to switch to NewtonsoftJson serialization (from package Microsoft.AspNetCore.Mvc.NewtonsoftJson) Call this in Startup.cs in the ConfigureServices method: services.AddControllers().AddNewtonsoftJson(); After this, your constructor will be called by deserialization. Extra info: I am using ASP Net Core 3.1 Later Edit: I wanted to give more info on this, as it … Read more
