The problem is the following: when an object implements IEnumerable, JSON.net identifies it as an array of values and serializes it following the array Json syntax (that does not include properties), e.g. : [ {“FooProperty” : 123}, {“FooProperty” : 456}, {“FooProperty” : 789}] If you want to serialize it keeping the properties, you need to … Read more
I wanted something a bit more baked into the framework than what Jarrett suggested, so here’s what I did: JsonDataContractActionResult: public class JsonDataContractActionResult : ActionResult { public JsonDataContractActionResult(Object data) { this.Data = data; } public Object Data { get; private set; } public override void ExecuteResult(ControllerContext context) { var serializer = new DataContractJsonSerializer(this.Data.GetType()); String output … Read more
Using something like Boost Serialization, while by no means a standard, is a (for the most part) very well written library that does the grunt work for you. The last time I had to manually parse a predefined record structure with a clear inheritance tree, I ended up using the factory pattern with registrable classes … Read more
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
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
Interfaces define a contract and do not have any state of their own. Serialization is about saving and loading state into and out of an object model. Not much point to serializing something that holds no state. To answer the practical question of forcing an implementation of an interface to be Serializable – this is … Read more
Even though you are testing a service, you can apply the @TestMixin(ControllerUnitTestMixin) annotation to your test class to get Grails to set up the JSON converter.
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 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
Create your own TypeAdapter public class MyTypeAdapter extends TypeAdapter<TestObject>() { @Override public void write(JsonWriter out, TestObject value) throws IOException { out.beginObject(); if (!Strings.isNullOrEmpty(value.test1)) { out.name(“test1”); out.value(value.test1); } if (!Strings.isNullOrEmpty(value.test2)) { out.name(“test2”); out.value(value.test1); } /* similar check for otherObject */ out.endObject(); } @Override public TestObject read(JsonReader in) throws IOException { // do something similar, but the … Read more
