serialization

问题 System.out.println("Java is awesome!"); Pardon my enthusiasm; I just can't believe how powerful Java is, what with its ability to not only save objects (and load them), but also with its main purpose, to send them over a network. This is exactly what I must do, for I am conducting a beta-test. In this beta-test, I have given the testers a version of the game that saves the data as Objects in a location most people don't know about (we are the enlightened ones hahaha). This would work fine and

问题 In Java we implement an interface Serializable that defines no method (also called a marker interface). But suppose I have an interface without any method just like a Serializable interface, can I make it work just like that, meaning that I would be able to use my interface instead of the Serializable ? Thanks 回答1: Only Serializable will mark an object as being compatible with Java's built-in serialization machinery. You can create other empty interfaces, but they won't mean the same thing.

问题 I have base class which is serialized. [ProtoContract] public class Web2PdfEntity { [ProtoMember(1)] public string Title { get; set; } [ProtoMember(2)] public string CUrl { get; set; } } I would like to deserialize Web2PdfEntity class to Web2PdfServer which is inherited from Web2PdfEntity. public class Web2PdfServer : Web2PdfEntity { public void MyServerMethod {} public void MyServerMethod2{} } I have tried to use code below to deserialize class, unfortunately the properties are not set. var

问题 Is there any way to add fields to a DataSet which will be serialized along with the table information when the DataSet is serialized in XML? I have some information that describes the DataSet that I want to try to include inside it when I throw it around in XML. I've tried adding fields and classes in the partial class Visual Studio generates for you for validation methods but I can't seem to get them to show up alongside the table information in the XML file either when myDataSet.WriteXML()

问题 I have some trouble on javafx FILE IO. I have implemented Serializable but there is also some wrong. Thank you for your help. 1.Appdata class package data; import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.FileOutputStream; import java.io.IOException; import java.io.ObjectInputStream; import java.io.ObjectOutputStream; import java.io.Serializable; import javafx.beans.property.SimpleStringProperty; import javafx.collections.FXCollections; import javafx

问题 I ran against another issue with shove (see Shove knowing about an object but unable to retrieve it ), but this time I've got a pretty simple repro showing why the dump/load doesn't work. Looking at the def in C:\Python27\lib\site-packages\shove-0.5.0-py2.7.egg\shove\base.py for loads/dumps, it refers to ld,optimize in stuf.utils. How come the below does not work? >>> from stuf.utils import ld,optimize; d=[{'A':1},{'A':1}]; ld(optimize(d)) [{'A': 1}, {'A': 1}] >>> from stuf.utils import ld

问题 I've been using the Newtonsoft.Json and Newtonsoft.Json.Fsharp libraries to create a new JSON serializer and stream to a file. I like the ability to stream to a file because I'm handling large files and, prior to streaming, often ran into memory issues. I stream with a simple fx: open Newtonsoft.Json open Newtonsoft.Json.FSharp open System.IO let writeToJson (path: string) (obj: 'a) : unit = let serialized = JsonConvert.SerializeObject(obj) let fileStream = new StreamWriter(path) let

问题 Can I deserialize an object in the Silverlight 3.0 runtime that was serialized using the full .NET 2.0 runtime using the BinaryFormatter? I am using the following code to serialize an object to a ByteArray which we write to a DB table: MemoryStream serStream = new MemoryStream(); BinaryFormatter binFormatter = new BinaryFormatter(); binFormatter.Serialize(serStream, csMetric); serStream.Position = 0; return serStream.ToArray(); The Silverlight client then needs to retrieve this binary data

问题 I'm trying to serialize the state of my game on Windows Phone 7, and so made a "Save" struct so I could easily convert all the states into an XML doc using DataContractSerializer. The Save() code worked fine when I just serialized each data member of the Gamestate individually. However this led to a multiple xml root error, so I made the "Save" class to act as the sole root. Now I get a security exception whenever I try and call DataContractSerializer.WriteObject() on anything. I've been
