  • xmlns='' was not expected when deserializing nested classes

    - by Mavrik
    I have a problem when attempting to serialize class on a server, send it to the client and deserialize is on the destination. On the server I have the following two classes: [XmlRoot("StatusUpdate")] public class GameStatusUpdate { public GameStatusUpdate() {} public GameStatusUpdate(Player[] players, Command command) { this.Players = players; this.Update = command; } [XmlArray("Players")] public Player[] Players { get; set; } [XmlElement("Command")] public Command Update { get; set; } } and [XmlRoot("Player")] public class Player { public Player() {} public Player(PlayerColors color) { Color = color; ... } [XmlAttribute("Color")] public PlayerColors Color { get; set; } [XmlAttribute("X")] public int X { get; set; } [XmlAttribute("Y")] public int Y { get; set; } } (The missing types are all enums). This generates the following XML on serialization: <?xml version="1.0" encoding="utf-16"?> <StatusUpdate> <Players> <Player Color="Cyan" X="67" Y="32" /> </Players> <Command>StartGame</Command> </StatusUpdate> On the client side, I'm attempting to deserialize that into following classes: [XmlRoot("StatusUpdate")] public class StatusUpdate { public StatusUpdate() { } [XmlArray("Players")] [XmlArrayItem("Player")] public PlayerInfo[] Players { get; set; } [XmlElement("Command")] public Command Update { get; set; } } and [XmlRoot("Player")] public class PlayerInfo { public PlayerInfo() { } [XmlAttribute("X")] public int X { get; set; } [XmlAttribute("Y")] public int Y { get; set; } [XmlAttribute("Color")] public PlayerColor Color { get; set; } } However, the deserializer throws an exception: There is an error in XML document (2, 2). <StatusUpdate xmlns=''> was not expected. What am I missing or doing wrong?

  • Using methods from the "outer" class in inner classes

    - by devoured elysium
    When defining nested classes, is it possible to access the "outer" class' methods? I know it's possible to access its attributes, but I can't seem to find a way to use its methods. addMouseListener(new MouseAdapter() { @Override public void mouseClicked(MouseEvent e) { if (e.getClickCount() == 2 && //<-- Here I'd like to } // reference a method }); //from the class where //addMouseListener() is defined! Thanks

  • Java method: retrieve the inheriting type

    - by DrDro
    I have several classes that extend C and I would need a method that accepts any argument of type C. But in this method I would like to know if I'm dealing with A or B. * public A extends C public B extends C public void goForIt(C c)() If I cast how can I retrieve the type in a clean way (I just read using getClass or instanceof is often not the best way). *Sorry but I can't type closing braces

  • Abstract classes and Pod::Coverage

    - by Ken Williams
    I've recently started to try to use Dist::Zilla for maintaining Path::Class. I added the [PodCoverageTests] plugin, and it's reporting some failures in the Path::Class::Entity class, which is the abstract base class for Path::Class::File and Path::Class::Dir. What I'd like is some way to tell the testing code that Entity doesn't need docs, but its two derived classes do - even though the methods are only defined in the parent class. Anyone know some way to do that?

  • C# class type - How to determine whether it is a standard .net framework class

    - by HorstWalter
    C# / .net framework What is the most reliable way to determine whether a class (type) is a class provided by the .net framework and not any of my classes or 3rd party library classes. I have tested some approaches The namespace, e.g. starting with "System." The Codebase of the assembly, where the dll is located All this "feels" a little clumsy though it works. Question: What is the easiest and most reliable way to determine this?

  • Using nested classes for constants?

    - by antirysm
    What's wrong with using nested classes to group constants? Like so: public static class Constants { public static class CategoryA { public const string ValueX = "CatA_X"; public const string ValueY = "CatA_Y"; } public static class CategoryB { public const string ValueX = "CatB_X"; public const string ValueY = "CatB_Y"; } } Used like so: Console.WriteLine(Constants.CategoryA.ValueY); Console.WriteLine(Constants.CategoryB.ValueX); You could also make the "Constants"-class partial...

  • pagerAnchorBuilder - trying to add classes

    - by Bert Murphy
    I'm using Cycle2 to build a carousel gallery and I've run into a little problem regarding styling the pager buttons. What I've gathered is that Cycle2 creates its own pager span tags for each slide which is a bummer becaus I've already styled my the sub-nav markup. This should be a minor issue as long as I can assign individual classes to the spans and change my css accordingly. However, I can't get this to work. TLDR: I was hoping that I could use pagerAnchorBuilder to create individual classes for each span. I can't. Help. The original markup (pre Cycle2) looks like the following: <div id ="sub-nav" class="sub-nav"> <ul> <li><a id="available" class="available" href="#"></a></li> <li><a id="reliable" class="reliable" href="#"></a></li> <li><a id="use" class="use" href="#"></a></li> <li><a id="reports" class="reports" href="#"></a></li> <li class="last"><a id="software" class="software" href="#"></a></li> </ul> </div> With Cycle2 it looks like this (note the addition of the span tags) <div id ="sub-nav" class="sub-nav"> <ul> <li><a id="available" class="available" href="#"></a></li> <li><a id="reliable" class="reliable" href="#"></a></li> <li><a id="use" class="use" href="#"></a></li> <li><a id="reports" class="reports" href="#"></a></li> <li class="last"><a id="software" class="software" href="#"></a></li> </ul> <span class="cycle-pager-active">•</span><span>•</span><span>•</span><span>•</span><span>•</span></nav> </div> Cycle2 $('#sliding-gallery ul').cycle({ fx: 'carousel', carouselVisible: 1, speed: 'fast', timeout: 10000, slides: '>li', next: '.next', prev: '.prev', pager: '.sub-nav', pagerAnchorBuilder: function(idx, slide) { return '.sub-nav span:eq(' + idx + ')'; } });

  • C# / IronPython Interop and the "float" data type

    - by Adam Haile
    Working on a project that uses some IronPython scripts to as plug-ins, that utilize functionality coded in C#. In one of my C# classes, I have a property that is of type: Dictionary<int, float> I set the value of that property from the IronPython code, like this: mc = MyClass() mc.ValueDictionary = Dictionary[int, float]({1:0.0, 2:0.012, 3:0.024}) However, when this bit of code is run, it throws the following exception: Microsoft.Scripting.ArgumentTypeException was unhandled by user code Message=expected Dictionary[int, Single], got Dictionary[int, float] To make things weirder, originally the C# code used Dictionary<int, double> but I could not find a "double" type in IronPython, tried "float" on a whim and it worked fine, giving no errors. But now that it's using float on both ends (which it should have been using from the start) it errors, and thinks that the C# code is using the "Single" data type?! I've even checked in the object browser for the C# library and, sure enough, it shows as using a "float" type and not "Single"

  • Subclassing and adding data members

    - by Marius
    I have an hierarchy of classes that looks like the following: class Critical { public: Critical(int a, int b) : m_a(a), m_b(b) { } virtual ~Critical() { } int GetA() { return m_a; } int GetB() { return m_b; } void SetA(int a) { m_a = a; } void SetB(int b) { m_b = b; } protected: int m_a; int m_b; }; class CriticalFlavor : public Critical { public: CriticalFlavor(int a, int b, int flavor) : Critical(a, b), m_flavor(flavor) { } virtual ~CriticalFlavor() { } int GetFlavor() { return m_flavor; } void SetFlavor(int flavor) { m_flavor = flavor; } protected: int m_flavor; }; class CriticalTwist : public Critical { public: CriticalTwist(int a, int b, int twist) : Critical(a, b), m_twist(twist) { } virtual ~CriticalTwist() { } int GetTwist() { return m_twist; } void SetTwist(int twist) { m_twist = twist; } protected: int m_twist; }; The above does not seem right to me in terms of the design and what bothers me the most is the fact that the addition of member variables seems to drive the interface of these classes (the real code that does the above is a little more complex but still embracing the same pattern). That will proliferate when in need for another "Critical" class that just adds some other property. Does this feel right to you? How could I refactor such code? An idea would be to have just a set of interfaces and use composition when it comes to the base object like the following: class Critical { public: virtual int GetA() = 0; virtual int GetB() = 0; virtual void SetA(int a) = 0; virtual void SetB(int b) = 0; }; class CriticalImpl { public: CriticalImpl(int a, int b) : m_a(a), m_b(b) { } ~CriticalImpl() { } int GetA() { return m_a; } int GetB() { return m_b; } void SetA(int a) { m_a = a; } void SetB(int b) { m_b = b; } private: int m_a; int m_b; }; class CriticalFlavor { public: virtual int GetFlavor() = 0; virtual void SetFlavor(int flavor) = 0; }; class CriticalFlavorImpl : public Critical, public CriticalFlavor { public: CriticalFlavorImpl(int a, int b, int flavor) : m_flavor(flavor), m_critical(new CriticalImpl(a, b)) { } ~CriticalFlavorImpl() { delete m_critical; } int GetFlavor() { return m_flavor; } void SetFlavor(int flavor) { m_flavor = flavor; } int GetA() { return m_critical-GetA(); } int GetB() { return m_critical-GetB(); } void SetA(int a) { m_critical-SetA(a); } void SetB(int b) { m_critical-SetB(b); } private: int m_flavor; CriticalImpl* m_critical; };

  • XSD problem: The value of attribute on element is not valid with respect to its type

    - by Tom Brito
    (First of all, I'm trying to learn how to handle xsd files, I know very little) I got this xsd, and just copy to Eclipse IDE, and it says there an error on line 26: <xs:element name="Issuer" type="dkx:IssuerType" /> saying: cvc-attribute.3: The value 'dkx:IssuerType' of attribute 'type' on element 'xs:element' is not valid with respect to its type, 'QName'. Any idea what is this? (as this is an example file, I'm assuming it is an independent file, hope it is)

  • C++ Function Template With Flexible Return Type

    - by Ignatius Reza
    Let's say that we have a function like so template <class T, class T2> T getMin(T a, T2 b) { if(a < b) return a; return b; } if we call the function like so int a, b; long c; a = getMin(b, c); if c is < a, then the value of c will be type casted to int. Is it possible to make the return type flexible so that it would return an int, or long, or any other type considered smaller by "<" without being type casted?

    Hello, I have a templated class with a static value, like this: template <class TYPE> class A{ static TYPE value; }; in the code of a dll I assign the static value: code of DLL_1 A<float>::value = 2.0; I wish the value to be shared by all the dlls I'm using, i.e. I want that: code of DLL_2 printf("value on DLL_2 %f",A<float>::value); print out "2.0" any clues? thx

  • Get methods params type parsing wsdl file in a rails/ruby application

    - by Marco Sangiorgi
    Hi, I have a question about ruby and wsdl soap. I couldn't find a way to get each method's params and their type. For example, if I found out that a soap has a methods called "get_user_information" (using wsdlDriver) is there a way to know if this method requires some params and what type of params does it require (int, string, complex type, ecc..)? I'd like to be able to build html forms from a remote wsdl for each method... Sorry for my horrible English :D
