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
TL;DR: The field: part is known as a “use-site target”, and makes it clear that the annotation is applied to the backing field of the Kotlin property. It is not strictly necessary in this case, though it can make the code more readable. Explanation To simplify, let’s say you have: data class Repo( @field:SerializedName(“name”) var … Read more
First, serialization is writing the object to a file ‘as it is’. AFAIK, you cannot choose file formats and all. The serialized object (in a file) has its own ‘file format’ If you want to write the contents of an object (or a list of objects) to a CSV file, you can do it yourself, … Read more
The intent of the {propertyName}Specified pattern is documented in XML Schema Binding Support: MinOccurs Attribute Binding Support. It was added to support an XSD schema element in which: The <element> element is involved. minOccurs is zero. The maxOccurs attribute dictates a single instance. The data type converts to a value type. In this case, xsd.exe … Read more
You are stringifying a string, not an object: var str=”{“2003”:{“1”:{“2”:[“test”],”3″:[“test2″]}}}”; var obj = {“2003”:{“1”:{“2”:[“test”],”3″:[“test2″]}}}; console.log( JSON.stringify(str) ); // {\”2003\”:{\”1\”:{\”2\”:[\”test\”],\”3\”:[\”test2\”]}}} console.log( JSON.stringify(obj) ); // {“2003”:{“1”:{“2”:[“test”],”3″:[“test2”]}}}
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
It’s well known scala bug: https://issues.scala-lang.org/browse/SI-7005 Map#mapValues is not serializable We have this problem in our Spark apps, map(identity) solves the problem rdd.groupBy(_.segment).mapValues(v => …).map(identity)
The whole point of the Json() helper method is to serialize as JSON. If you want to return raw content, do that directly: return Content(jsonString, “application/json”);
Just to be sure, the Class in both VMs are sharing same compiled version of the classes? Could you try re-compiling and adding same jar to both VMs. I hope that is already taken care.
