serialization

问题 In my Google Web Toolkit project, I got the following error: com.google.gwt.user.client.rpc.SerializationException: Type ‘your.class.Type’ was not included in the set of types which can be serialized by this SerializationPolicy or its Class object could not be loaded. For security purposes, this type will not be serialized. What are the possible causes of this error? 回答1: GWT keeps track of a set of types which can be serialized and sent to the client. your.class.Type apparently was not on

问题 Seeing the power of Scala, I wonder if an arbitrary object graph could be serialized and deserialized to/from XML using built-in Scala language features and libraries (e.g. without XMLEncoder, XStream or JAXB). Unfortunately, I haven't found such a solution. What could you advise? 回答1: I don't know "if an arbitrary object graph could be serialized and deserialized to/from XML using built-in Scala language features and libraries," but since there are some native support for XML in Scala, I'll

Closed 6 months ago . i need to store Python structures made of lists / dictionaries, tuples into a human readable format. The idea is like using something similar to pickle, but pickle is not human-friendly. Other options that come to my mind are YAML (through PyYAML and JSON (through simplejson

问题 When i run this demo it's call TestBean's writeObject method which is private How is it possible ? Here is the Code: import java.io.FileOutputStream; public class Test { public static void main(String[] args) { try { TestBean testBean = test.new TestBean(); testBean.setSize(23); testBean.setWidth(167); FileOutputStream fos = new FileOutputStream(new File("d:\\serial.txt")); ObjectOutputStream oos = new ObjectOutputStream(fos); oos.writeObject(testBean); oos.close(); } catch (Exception e) { e

问题 I want to serialize/deserialize an object that has been instantiated by another object loaded from an assembly: Interfaces.cs (from a referenced assembly, Interfaces.dll) public interface ISomeInterface { ISettings Settings { get; set; } } public interface ISettings : ISerializable { DateTime StartDate { get; } } SomeClass.cs (from a referenced assembly, SomeClass.dll) public class SomeClass : ISomeInterface { private MySettings settings = new Settings(); public ISettings Settings { get {

问题 I currently playing with the XMLSerializer to understand how it works. I am able to serialize, save and de-serialize a single object without problem. However I run into problems when I try to de-serialize multiple objects. I get this error : Unhandled exception. System.InvalidOperationException: There is an error in XML document (10, 10). ---> System.Xml.XmlException: Unexpected XML declaration. The XML declaration must be the first node in the document, and no whitespace characters are

问题 For application configuration, I frequently will create a configuration class with configuration values for the application that I then deserialize into an object to utilize. The configuration object is usually databound to a user interface control so that the configuration can be changed and persisted by the user. The configuration class typically has default values assigned to the properties so that there is always a default configuration. This has worked well. I recently had a situation

问题 I serialize an array of large objects to a json http response stream. Now I want to deserialize these objects from the stream one at a time. Are there any c# libraries that will let me do this? I've looked at json.net but it seems I'd have to deserialize the complete array of objects at once. [{large json object},{large json object}.....] Clarification: I want to read one json object from the stream at a time and deserialize it. 回答1: In order to read the JSON incrementally, you'll need to use
