  • interface variables are final and static by default and methods are public and abstract

    - by sap
    The question is why it's been decided to have variable as final and static and methods as public and abstract by default. Is there any particular reason for making them implicit,variable as final and static and methods as public and abstract. Why they are not allowing static method but allowing static variable? We have interface to have feature of multiple inheritance in Java and to avoid diamond problem. But how it solves diamond problem,since it does not allow static methods. In the following program, both interfaces have method with the same name..but while implementing only one we implement...is this how diamond problem is solved? interface testInt{ int m = 0; void testMethod(); } interface testInt1{ int m = 10; void testMethod(); } public class interfaceCheck implements testInt, testInt1{ public void testMethod(){ System . out . println ( "m is"+ testInt.m ); System . out . println ( "Hi World!" ); } }

  • Apply [ThreadStatic] attribute to a method in external assembly

    - by Sen Jacob
    Can I use an external assembly's static method like [ThreadStatic] method? Here is my situation. The assembly class (which I do not have access to its source) has this structure public class RegistrationManager() { private RegistrationManager() {} public static void RegisterConfiguration(int ID) {} public static object DoWork() {} public static void UnregisterConfiguration(int ID) {} } Once registered, I cannot call the DoWork() with a different ID without unregistering the previously registered one. Actually I want to call the DoWork() method with different IDs simultaneously with multi-threading. If the RegisterConfiguration(int ID) method was [ThreadStatic], I could have call it in different threads without problems with calls, right? So, can I apply the [ThreadStatic] attribute to this method or is there any other way I can call the two static methods same time without waiting for other thread to unregister it? If I check it like the following, it should work. for(int i=0; i < 10; i++) { new Thread(new ThreadStart(() => Checker(i))).Start(); } public string Checker(int i) { public static void RegisterConfiguration(i); // Now i cannot register second time public static object DoWork(i); Thread.Sleep(5000); // DoWork() may take a little while to complete before unregistered public static void UnregisterConfiguration(i); }

  • Javascript: Static member variable containing object instances

    - by tom
    I have the following: function Preferences() { } Preferences.players = { 'player1': new Player() } players is a static member variable of Preferences and I'm trying to make it an object containing an instance of a Player. However, it doesn't appear to let me do this. It seems like it will allow me to define players if I make it a non-static member variable however. Like so: function Preferences() { var players = { 'player1' : new Player() } } Is it possible to create a static member variable containing instances of an object in JS?

  • Combining several static archives into a new one

    - by knight666
    I'm making a game engine for mobile devices. I want to compile my code, link it against a few static libraries and then combine my compiled code with those static libraries to form a new static library. However, my Google Fu is abandoning me. Suppose I have static libraries a.a, b.a and c.a and my code. I want to compile all that into awesome.a. How can I do that? I'm using CodeSourcery's arm-none-linux-gnueabi-ar by the way. Thanks in advance.

  • C#: An object reference is required for the non-static field, method, or Property

    - by Omin
    I feel bad for asking this when there are so many questions that are related but I was not able to find/understand the answer I am looking for. // 2. Develop a program to convert currency X to currency Y and visa versa. using System; class Problem2 { static void Main (string[] args) { while (true) { Console.WriteLine ("1. Currency Conversion from CAD to Won"); Console.WriteLine ("2. Currency Conversion from Won to Cad"); Console.Write ("Choose from the Following: (1 or 2)? "); int option = int.Parse( Console.ReadLine() ); //double x; if (option == 1) { Console.WriteLine ("Type in the amount you would like to Convert CAD to Won: "); //double y =double.Parse( Console.ReadLine()); //Console.WriteLine( cadToWon( y ) ); Console.WriteLine( cadToWon( double.Parse( Console.ReadLine() ) )); } if (option == 2) { Console.WriteLine ("Type in the amount you would like to Convert Won to CAD: "); Console.WriteLine( wonToCad (double.Parse( Console.ReadLine()))); } } } double cadToWon( double x ) { return x * 1113.26; } double wonToCad( double x) { return x / 1113.26; } } This give me the Error messgae "An object reference is required for the non-static field, method, or property 'Problem2..." I know that I'll be able to run the program if I add static infront of the methods but I'm wondering why I need it (I think it's because Main is static?) and what do I need to change in order to use these methods without adding static to them? Thank you

  • Why should Java ThreadLocal variables be static

    - by kellyfj
    I was reading that JavaDoc for Threadlocal here http://java.sun.com/j2se/1.5.0/docs/api/java/lang/ThreadLocal.html and it says "ThreadLocal instances are typically private static fields in classes that wish to associate state with a thread (e.g., a user ID or Transaction ID). " But my question is why did they choose to make it static (typically) - it makes it a bit confusing to have "per thread" state but its static?

    I checked out the microsoft documents. it shows how to create a static library upon creation of the project. but not necessarily on how to convert a previously made project, into a static library. So my question is, where do I go to turn my previously made project, into a static lib. so I can include it in my other projects

  • Extension methods on a static object

    - by Max Malygin
    I know (or so I hear) that writing extension methods for a single stand alone .net class (not an implementation of IEnumerable) is potential code smell. However, for the sake of making the life easier I need to attach a method to the ConfigurationManager class in asp.net. It's a static object so this won't work: public static List<string> GetSupportedDomains(this ConfigurationManager manager) { //the manager needs to be static. } So the question is - is it possible to write an extension method for a static class in .net?

  • Is it possible for a parent to use a child's constant or static variables from inside a static metho

    - by ryeguy
    Below is an example of what I'm trying to do. The parent can't access any of the child's variables. It doesn't matter what technique I use (static or constants), I just need some kind of functionality like this. class ParentClass { public static function staticFunc() { //both of these will throw a (static|const) not defined error echo self::$myStatic; echo self::MY_CONSTANT; } } class ChildClass extends ParentClass { const MY_CONSTANT = 1; public static $myStatic = 2; } ChildClass::staticFunc();

  • Static referencing error

    - by maxflow
    public class HelloWorld { public static void main(String [] args) { char[] b = {'a', 'b', 'a', 'c'}; int p = 4; deleteRepeats(b, p); } public void deleteRepeats(char[] a, int size) { int currentElement; currentElement = 0; do { for (int i = currentElement; i < size-1; i++) { if (a[currentElement] == a[i+1]) a[i+1] = ' '; } currentElement++; } while (currentElement < size-1); } } I get the error: non-static method deleteRepeats(char[],int) cannot be referenced from a static context deleteRepeats(b,p); Can someone tell me what this means? I tried removing "static" from the main method, but I get the error: Exception in thread "main" java.lang.NoSuchMethodError: main. Thanks in advance

  • TFS 2010 SDK: Connecting to TFS 2010 Programmatically&ndash;Part 1

    - by Tarun Arora
    Technorati Tags: Team Foundation Server 2010,TFS 2010 SDK,TFS API,TFS Programming,TFS ALM   Download Working Demo Great! You have reached that point where you would like to extend TFS 2010. The first step is to connect to TFS programmatically. 1. Download TFS 2010 SDK => http://visualstudiogallery.msdn.microsoft.com/25622469-19d8-4959-8e5c-4025d1c9183d?SRC=VSIDE 2. Alternatively you can also download this from the visual studio extension manager 3. Create a new Windows Forms Application project and add reference to TFS Common and client dlls Note - If Microsoft.TeamFoundation.Client and Microsoft.TeamFoundation.Common do not appear on the .NET tab of the References dialog box, use the Browse tab to add the assemblies. You can find them at %ProgramFiles%\Microsoft Visual Studio 10.0\Common7\IDE\ReferenceAssemblies\v2.0. using Microsoft.TeamFoundation.Client; using Microsoft.TeamFoundation.Framework.Client; using Microsoft.TeamFoundation.Framework.Common;   4. There are several ways to connect to TFS, the two classes of interest are, Option 1 – Class – TfsTeamProjectCollectionClass namespace Microsoft.TeamFoundation.Client { public class TfsTeamProjectCollection : TfsConnection { public TfsTeamProjectCollection(RegisteredProjectCollection projectCollection); public TfsTeamProjectCollection(Uri uri); public TfsTeamProjectCollection(RegisteredProjectCollection projectCollection, IdentityDescriptor identityToImpersonate); public TfsTeamProjectCollection(Uri uri, ICredentials credentials); public TfsTeamProjectCollection(Uri uri, ICredentialsProvider credentialsProvider); public TfsTeamProjectCollection(Uri uri, IdentityDescriptor identityToImpersonate); public TfsTeamProjectCollection(RegisteredProjectCollection projectCollection, ICredentials credentials, ICredentialsProvider credentialsProvider); public TfsTeamProjectCollection(Uri uri, ICredentials credentials, ICredentialsProvider credentialsProvider); public TfsTeamProjectCollection(RegisteredProjectCollection projectCollection, ICredentials credentials, ICredentialsProvider credentialsProvider, IdentityDescriptor identityToImpersonate); public TfsTeamProjectCollection(Uri uri, ICredentials credentials, ICredentialsProvider credentialsProvider, IdentityDescriptor identityToImpersonate); public override CatalogNode CatalogNode { get; } public TfsConfigurationServer ConfigurationServer { get; internal set; } public override string Name { get; } public static Uri GetFullyQualifiedUriForName(string name); protected override object GetServiceInstance(Type serviceType, object serviceInstance); protected override object InitializeTeamFoundationObject(string fullName, object instance); } } Option 2 – Class – TfsConfigurationServer namespace Microsoft.TeamFoundation.Client { public class TfsConfigurationServer : TfsConnection { public TfsConfigurationServer(RegisteredConfigurationServer application); public TfsConfigurationServer(Uri uri); public TfsConfigurationServer(RegisteredConfigurationServer application, IdentityDescriptor identityToImpersonate); public TfsConfigurationServer(Uri uri, ICredentials credentials); public TfsConfigurationServer(Uri uri, ICredentialsProvider credentialsProvider); public TfsConfigurationServer(Uri uri, IdentityDescriptor identityToImpersonate); public TfsConfigurationServer(RegisteredConfigurationServer application, ICredentials credentials, ICredentialsProvider credentialsProvider); public TfsConfigurationServer(Uri uri, ICredentials credentials, ICredentialsProvider credentialsProvider); public TfsConfigurationServer(RegisteredConfigurationServer application, ICredentials credentials, ICredentialsProvider credentialsProvider, IdentityDescriptor identityToImpersonate); public TfsConfigurationServer(Uri uri, ICredentials credentials, ICredentialsProvider credentialsProvider, IdentityDescriptor identityToImpersonate); public override CatalogNode CatalogNode { get; } public override string Name { get; } protected override object GetServiceInstance(Type serviceType, object serviceInstance); public TfsTeamProjectCollection GetTeamProjectCollection(Guid collectionId); protected override object InitializeTeamFoundationObject(string fullName, object instance); } }   Note – The TeamFoundationServer class is obsolete. Use the TfsTeamProjectCollection or TfsConfigurationServer classes to talk to a 2010 Team Foundation Server. In order to talk to a 2005 or 2008 Team Foundation Server use the TfsTeamProjectCollection class. 5. Sample code for programmatically connecting to TFS 2010 using the TFS 2010 API How do i know what the URI of my TFS server is, Note – You need to be have Team Project Collection view details permission in order to connect, expect to receive an authorization failure message if you do not have sufficient permissions. Case 1: Connect by Uri string _myUri = @"https://tfs.codeplex.com:443/tfs/tfs30"; TfsConfigurationServer configurationServer = TfsConfigurationServerFactory.GetConfigurationServer(new Uri(_myUri)); Case 2: Connect by Uri, prompt for credentials string _myUri = @"https://tfs.codeplex.com:443/tfs/tfs30"; TfsConfigurationServer configurationServer = TfsConfigurationServerFactory.GetConfigurationServer(new Uri(_myUri), new UICredentialsProvider()); configurationServer.EnsureAuthenticated(); Case 3: Connect by Uri, custom credentials In order to use this method of connectivity you need to implement the interface ICredentailsProvider public class ConnectByImplementingCredentialsProvider : ICredentialsProvider { public ICredentials GetCredentials(Uri uri, ICredentials iCredentials) { return new NetworkCredential("UserName", "Password", "Domain"); } public void NotifyCredentialsAuthenticated(Uri uri) { throw new ApplicationException("Unable to authenticate"); } } And now consume the implementation of the interface, string _myUri = @"https://tfs.codeplex.com:443/tfs/tfs30"; ConnectByImplementingCredentialsProvider connect = new ConnectByImplementingCredentialsProvider(); ICredentials iCred = new NetworkCredential("UserName", "Password", "Domain"); connect.GetCredentials(new Uri(_myUri), iCred); TfsConfigurationServer configurationServer = TfsConfigurationServerFactory.GetConfigurationServer(new Uri(_myUri), connect); configurationServer.EnsureAuthenticated();   6. Programmatically query TFS 2010 using the TFS SDK for all Team Project Collections and retrieve all Team Projects and output the display name and description of each team project. CatalogNode catalogNode = configurationServer.CatalogNode; ReadOnlyCollection<CatalogNode> tpcNodes = catalogNode.QueryChildren( new Guid[] { CatalogResourceTypes.ProjectCollection }, false, CatalogQueryOptions.None); // tpc = Team Project Collection foreach (CatalogNode tpcNode in tpcNodes) { Guid tpcId = new Guid(tpcNode.Resource.Properties["InstanceId"]); TfsTeamProjectCollection tpc = configurationServer.GetTeamProjectCollection(tpcId); // Get catalog of tp = 'Team Projects' for the tpc = 'Team Project Collection' var tpNodes = tpcNode.QueryChildren( new Guid[] { CatalogResourceTypes.TeamProject }, false, CatalogQueryOptions.None); foreach (var p in tpNodes) { Debug.Write(Environment.NewLine + " Team Project : " + p.Resource.DisplayName + " - " + p.Resource.Description + Environment.NewLine); } }   Output   You can download a working demo that uses TFS SDK 2010 to programmatically connect to TFS 2010.

  • SmartOS Virtualization with one public IP address

    - by matejkramny
    Is it possible? (title of this question) Googling Virtualization with one public IP address yields nothing useful What I have: SmartOS on a dedicated server. Dedicated server has one public IP address. What I want to do: Host multiple guest OS from that server Problem: Access to the guest through the (server that virtualizes the guest)'s IP address. Is this possible at all? Sorry, newbie to all this Research http://www.machine-unix.com/beginning-with-smartos/#comment-7256 Does not solve my problem - the guide sets up an internal IP http://blog.bgentil.fr/smartos-use-global-zone-as-gateway-for-guests.html Ideas Perhaps it is possible to do host-based translation like with nginx proxy?

  • Using Static Public IPs and Private DHCP IPs on the Same Router

    - by Andrew Larsson
    I have a subnet of public IP addresses that my ISP has provided me with. They are routed through my router (how profound) that has a a static IP. I have successfully assigned the IPs from that subnet to various devices on my network. This works just fine, they get their own public IP, they can access the Internet, and the Internet can access them. However, I would like to also assign some private IPs on my network through that same router and put them behind NAT. Is this even possible? Could a VLAN be of use? I would like to avoid putting another router on the network, which makes this is quite an awkward question.

  • Public IP Routing over Private GRE tunnel

    - by Paul
    I have a GRE tunnel configured between two linux boxes. The tunnel works fine. I can ping from each host the other private ip. Head privateip: 10.0.0.1 publicip: 8.8.8.8 Tail privateip: 10.0.0.2 publicip: 7.7.7.7 The public IP on Tail has the network block 9.9.9.0/23 statically routed over the 7.7.7.7 interface. The idea is to make the 9.9.9.0/23 ips work on servers on the 8.8.8.8 network. I configure the tail host to route the /23 block. I mounted a 9.9 IP on the head server. I can ping the 9.9 ip from the tail to the head. I can't ping the 9.9 ip from the public internet. I think I need to add some other routes because of gateway issues, but I can't seem to wrap my mind around it (not a router guy, just beating my way through something that I have never done before and vaguely understand) --danks

  • How to post a blog without public access

    - by joaoc
    I want to keep a blog with pictures and videos of my kid growing up but I don't want it to be open to the public. I just want me and my wife to be able to post to it and then share with grandparents and friends. I'm at the start so I would like a platform (blogger, wordpress, ...) that has these features and that also allows export of the data (if one day I want to migrate to a different platform). I've been trying out blogger which allows you to have a private blog. But when I upload images they get stored in a hard to guess URL but are otherwise public. Are there better options to this? For videos I think I am happy with embedding Vimeo videos since they ask for a password to be viewed but I am open to suggestions.
