serialization

问题 I have a HDF5 file and a list of objects that I need to store for saving functionality. For simplicity I want to create only one save file. Can I store H5 file, in my save file that I create with serialization (pickle) without opening H5 file. 回答1: You can put several files in one by using zipfile or tarfile for zipfile you would write the database files and writestr your pickle.dumps ed data. for tarfile you would add the database file and gettarinfo , addfile your pickle.dump ed data from a

问题 I got a custom class Foo : class Foo { public: // getters and setters // ... private: QString string; QStringList list; int number; } The serialization of Foo has worked as expected: QDataStream &operator<<(QDataStream &stream, const Foo &foo) { stream<<foo.getString()<<foo.getList()<<foo.getNumber(); return stream; } but when I attempted to serialize QList<Foo> , I got error C2679: binary '<<' : no operator found which takes a right-hand operand of type “const Foo” which directed to the

问题 I have the following XML generated using a function FreezeAllAccountsForUser. I need to serialize only the following two columns for this function. How can I restrict the serialization to two columns? BankAccountID Status Note: The key point is that the scope of making this restriction should be only within the function FreezeAllAccountsForUser; not global .

问题 I use Jackson to serialize/deserialize JSON . I have a List<String> in which all elements inside are already serialized in JSON format. I would like to generate a big JSON from that List . In other word, I have: List<String> a = new ArrayList<>(); a[0] = JSON_0 a[1] = JSON_1 ... a[N] = JSON_N And I would like to render: [ {JSON_0}, {JSON_1}, ... {JSON_N} ] What is the best way to do so using Jackson ? 回答1: Probably the simpler solution would be to create ArrayNode and use addRawValue method:

问题 I am developing a java application which needs a special component for dynamic attributes. The arguments are serialized (using JSON) and stored in a database and then deserialized at runtime. All attributes are displayed in a JTable with 3 columns (attribute name, attribute type and attribute value) and stored in a hashmap. I have currently two problems to solve: The hashmap can also store objects and the objects can be set to null. And if set to null i dont know which class they belong to.

问题 I am trying to convert a json string to an object using Newtonsoft.json, but I am having some problems with the following conversion. I wonder if some one can explain this. thanks. AddFaceResponse ir = JsonConvert.DeserializeObject<AddFaceResponse>(responseContentStr); this is the json string responseContentStr [{ "faceId": "1fe48282-a3b0-47d1-8fa8-67c4fac3d984", "faceRectangle": { "top": 80, "left": 50, "width": 147, "height": 147 } }] This is my model object. public class AddFaceResponse {

问题 I have a problem with serializing a response in REST application.

问题 When working with 5-tier architecture (front-end => interface tier => business tier => database tier => database) using WCF service as the interface tier, having the client applications calling it's methods, should I use also WCF service for the business and database tiers? I ask because of all the serialization / deserialization that will be going on between the 3 services is probably going to consume a lot of CPU for the server, and have a performance impact on the application as a whole,

问题 I've been wondering if it's possible to do this. It would be a great help in cases where an XML response has incorrect values that are needing to be mapped to enums. The case I'm dealing with specifically is when an expected value has a trailing space and the enum is expecting it without. XML: <Foo> <Bar>EnumValue </Bar> </Foo> Enum: public enum MyEnum { [XmlEnum("EnumValue")] EnumValue } Class: public class Foo { [XmlElement("Bar")] public MyEnum myEnum { get; set; } } I've investigated
