serialization

问题 Suppose I have a Serializable class ShapeHolder that owns an object that implements a Serializable Shape interface. I want to make sure the correct concrete shape object is saved (and the correct type is later restored). How can I accomplish this? interface Shape extends Serializable {} class Circle implements Shape { private static final long serialVersionUID = -1306760703066967345L; } class ShapeHolder implements Serializable { private static final long serialVersionUID =

问题 I am trying to create a deep clone of an object using the following method. public static T DeepClone<T>(this T target) { using (MemoryStream stream = new MemoryStream()) { BinaryFormatter formatter = new BinaryFormatter(); formatter.Serialize(stream, target); stream.Position = 0; return (T)formatter.Deserialize(stream); } } This method requires an object which is Serialized i.e. an object of a class who is having an attribute "Serializable" on it. I have a class which is having attribute

问题 I am doing some research into the Memento Pattern and I am generally new to behavioural patterns and with my research I have been getting pretty confused. One of the main things I have been getting confused on is the differences between the Memento Pattern and Serialization. From what I can gather both can be used to store objects and have them brought back at a later date but I have not been able to find a clear cut answer on what the key differences between them are, maybe I have missed

问题 What's the best way (completeness and performance) in Golang to serialize and deserialize a struct to string and vice versa? for example, if I have this struct: struct Session { Properties map[string]interface{} Permissions []int64 } I want to store it on Redis and fetch it back. I have tried to save, int and string, it's fine, but how to store struct object? conn := redisConnectors.Get() // set example _, err := conn.Do(`SETEX`, `uid_key`, EXPIRE_SEC, user_id) _, err = conn.Do(`SETEX`,

问题 Are there any compatibility issues to take care of when serailizing an object in .NET and then deserializing in Java? I am facing problems in de-serializing an object in java which has been serialized in .NET Here is the detailed problem statement: In .NET platform i have a cookie. 1. Cookie is serialized 2. then it is encrypted using Triple DES algo. 3. Send it across to Java application In Java platform 1. Decrypt the cookie using Triple DES which gives some bytes 2. Deserialize the bytes

问题 I have an array in php of this format: <?php $value = array("id" => 42, "user" => "superman"); echo serialize($value); ?> Serialized : a:2:{s:2:"id";i:42;s:4:"user";s:8:"superman";} I receive this into a String in java. How I can do for deserialize this in java ? I know the implements Serializable in java but not work in this case. I want to create an object in this kind of format : import java.io.Serializable; public class Serial implements Serializable{ private int mId; private String mUser

问题 I have a very straight forward issue here. I need to take JSON coming from the API and convert it to objects I created for them. This far, it will deserialize them into my List but each Metric object has null values JSON COMING IN { "metrics": [ { "metric": { "type": 1, "name": "slide-11-start", "value": "1287249598295", "sessionID": "" } }, { "metric": { "type": 1, "name": "slide-21-start", "value": "1287249601368", "sessionID": "" } }, { "metric": { "type": 7, "name": "resolution", "value":

问题 I'm using Newtonsoft.Json to parse object to json string. It returns somethink like this: {\"code\":-1,\"idName\":\"empty\",\"idValue\":0,\"message\":\"Failed,can not read object from body\"} it is not a valid json string i think, anyone can work me out? What I want is something like this: {"code":-1,"idName":"empty\",\"idValue\":0,\"message\":\"Failed,can not read object from body\"} public static class CommonUtility { // format response string public static string FormatResponseString(int

问题 A project I'm working on requires serializing a data structure before shutting down and restores its state from this serialized data when it start up again. Last year, we were building for .NET 1.1, and ran into a tricky issue where our code ran on .NET 2.0 a customer upgraded with some software that somehow set 1.1 as default our code ran on .NET 1.1 and was unable to deserialize its stored state This particular issue was "resolved" by barring that particular software upgrade, and shouldn't
