  • Objective-C method implementation nuances

    - by altdotnetgeek
    I have just started to develop for the iPhone and am in the process of learning Objective-C. I have seen some code that implements a method in the @implementation side of a class like this: -(void)myMethod; { // method body } What makes this interesting is that there is no mention of myMethod in the @interface for the class. I tried a sample project with this and when I compile I get a warning from XCode that myMethod may not be seen by the calling code. Can anyone tell me what is going on? Thanks!

  • overriding protected internal with protected!

    - by Asad Butt
    This is an extension for this question asked an hour ago. We cannot modify the access modifiers, when overriding a virtual method in derived class. Consider Control class in System.Web.UI namespace public class Control : IComponent, IDisposable,... { protected internal virtual void CreateChildControls() { } . . } Now Consider This public class someClass : System.Web.UI.Control { // This should not compile but it does protected override void CreateChildControls() { } // This should compile but it does not protected internal override void CreateChildControls() { } } can any body explain this ? Thanks

  • C++ method chaining including class constructor

    - by jena
    Hello, I'm trying to implement method chaining in C++, which turns out to be quite easy if the constructor call of a class is a separate statement, e.g: Foo foo; foo.bar().baz(); But as soon as the constructor call becomes part of the method chain, the compiler complains about expecting ";" in place of "." immediately after the constructor call: Foo foo().bar().baz(); I'm wondering now if this is actually possible in C++. Here is my test class: class Foo { public: Foo() { } Foo& bar() { return *this; } Foo& baz() { return *this; } }; I also found an example for "fluent interfaces" in C++ (http://en.wikipedia.org/wiki/Fluent_interface#C.2B.2B) which seems to be exactly what I'm searching for. However, I get the same compiler error for that code. Thanks in advance for any hint. Best, Jean

  • How to route outbound traffic to specific domain "XYZ.org" via a specific NIC or public/static IP?

    - by user139943
    Within the next week or so, I'll be setting up an AT&T U-verse modem with 5 usable static public IP addresses. I plan to register a domain name to 1 of the 5 static IPs (remaining 4 unregistered), and run a website from a single server setup in my home LAN. I'll skip the long winded reason why, but I need to somehow route outbound traffic (originating from my server) destined for one public domain (i.e. http://www.sample.org) through one of the UNREGISTERED static IP addresses ONLY. Basically, I want this public domain to see connections coming from an IP address and not my domain name. If it makes it easier, this can apply to all outbound traffic from my server as long as it doesn't impact users browsing my website! Inbound connections should go through the domain name / registered public IP. Can I accomplish this with my single server with one or multiple NICs? Do I need multiple servers and set one up as a proxy? Please help as my background is in software and not networking, and I don't think I can accomplish this at a software level (e.g. Java). Thanks.

  • MVC Portable Areas &ndash; Deploying Static Files

    - by Steve Michelotti
    This is the second post in a series related to build and deployment considerations as I’ve been exploring MVC Portable Areas: #1 – Using Web Application Project to build portable areas #2 – Conventions for deploying portable area static files #3 – Portable area static files as embedded resources As I’ve been digging more into portable areas, one of the things I’ve liked best is the deployment story which enables my *.aspx, *.ascx pages to be compiled into the assembly as embedded resources rather than having to maintain all those files separately. In traditional web forms, that was always the thing to prevented developers from utilizing *.ascx user controls across projects (see this post for using portable areas in web forms).  However, though the aspx pages are embedded, the supporting static files (e.g., images, css, javascript) are *not*. Most of the demos available online today tend to brush over this issue and focus solely on the aspx side of things. But to create truly robust portable areas, it’s important to have a good story for these supporting files as well.  I’ve been working with two different approaches so far (of course I’d really like to hear if other people are using alternatives). Scenario For the approaches below, the scenario really isn’t that important. It could be something as trivial as this partial view: 1: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %> 2: <img src="<%: Url.Content("~/images/arrow.gif") %>" /> Hello World! The point is that there needs to be careful consideration for *any* scenario that links to an external file such as an image, *.css, *.js, etc. In the example shown above, it uses the Url.Content() method to convert to a relative path. But this method won’t necessary work depending on how you deploy your portable area. One approach to address this issue is to build your portable area project with MSDeploy/WebDeploy so that it is packaged properly before incorporating into the host application. All of the *.cs files are removed and the project is ready for xcopy deployment – however, I do *not* need the “Views” folder since all of the mark up has been compiled into the assembly as embedded resources. Now in the host application we create a folder called “Modules” and deploy any portable areas as sub-folders under that: At this point we can add a simple assembly reference to the Widget1.dll sitting in the Modules\Widget1\bin folder. I can now render the portable image in my view like any other portable area. However, the problem with that is that the view results in this:   It couldn’t find arrow.gif because it looked for /images/arrow.gif and it was *actually* located at /images/Modules/Widget1/images/arrow.gif. One solution is to make the physical location of the portable configurable from the perspective of the host like this: 1: <appSettings> 2: <add key="Widget1" value="Modules\Widget1"/> 3: </appSettings> Using the <appSettings> section is a little cheesy but it could be better formalized into its own section. In fact, if were you willing to rely on conventions (e.g., “Modules\{areaName}”) then then config could be eliminated completely. With this config in place, we could create our own Html helper method called Url.AreaContent() that “wraps” the OOTB Url.Content() method while simply pre-pending the area location path: 1: public static string AreaContent(this UrlHelper urlHelper, string contentPath) 2: { 3: var areaName = (string)urlHelper.RequestContext.RouteData.DataTokens["area"]; 4: var areaPath = (string)ConfigurationManager.AppSettings[areaName]; 5:   6: return urlHelper.Content("~/" + areaPath + "/" + contentPath); With these two items in place, we just change our Url.Content() call to Url.AreaContent() like this: 1: <img src="<%: Url.AreaContent("/images/arrow.gif") %>" /> Hello World! and the arrow.gif now renders correctly:     Since we’re just using our own Url.AreaContent() rather than the built-in Url.Content(), this solution works for images, *.css, *.js, or any externally referenced files.  Additionally, any images referenced inside a css file will work provided it’s a relative reference and not an absolute reference. An alternative to this approach is to build the static file into the assembly as embedded resources themselves. I’ll explore this in another post (linked at the top).

  • C#/.NET Little Wonders: The Nullable static class

    - by James Michael Hare
    Once again, in this series of posts I look at the parts of the .NET Framework that may seem trivial, but can help improve your code by making it easier to write and maintain. The index of all my past little wonders posts can be found here. Today we’re going to look at an interesting Little Wonder that can be used to mitigate what could be considered a Little Pitfall.  The Little Wonder we’ll be examining is the System.Nullable static class.  No, not the System.Nullable<T> class, but a static helper class that has one useful method in particular that we will examine… but first, let’s look at the Little Pitfall that makes this wonder so useful. Little Pitfall: Comparing nullable value types using <, >, <=, >= Examine this piece of code, without examining it too deeply, what’s your gut reaction as to the result? 1: int? x = null; 2:  3: if (x < 100) 4: { 5: Console.WriteLine("True, {0} is less than 100.", 6: x.HasValue ? x.ToString() : "null"); 7: } 8: else 9: { 10: Console.WriteLine("False, {0} is NOT less than 100.", 11: x.HasValue ? x.ToString() : "null"); 12: } Your gut would be to say true right?  It would seem to make sense that a null integer is less than the integer constant 100.  But the result is actually false!  The null value is not less than 100 according to the less-than operator. It looks even more outrageous when you consider this also evaluates to false: 1: int? x = null; 2:  3: if (x < int.MaxValue) 4: { 5: // ... 6: } So, are we saying that null is less than every valid int value?  If that were true, null should be less than int.MinValue, right?  Well… no: 1: int? x = null; 2:  3: // um... hold on here, x is NOT less than min value? 4: if (x < int.MinValue) 5: { 6: // ... 7: } So what’s going on here?  If we use greater than instead of less than, we see the same little dilemma: 1: int? x = null; 2:  3: // once again, null is not greater than anything either... 4: if (x > int.MinValue) 5: { 6: // ... 7: } It turns out that four of the comparison operators (<, <=, >, >=) are designed to return false anytime at least one of the arguments is null when comparing System.Nullable wrapped types that expose the comparison operators (short, int, float, double, DateTime, TimeSpan, etc.).  What’s even odder is that even though the two equality operators (== and !=) work correctly, >= and <= have the same issue as < and > and return false if both System.Nullable wrapped operator comparable types are null! 1: DateTime? x = null; 2: DateTime? y = null; 3:  4: if (x <= y) 5: { 6: Console.WriteLine("You'd think this is true, since both are null, but it's not."); 7: } 8: else 9: { 10: Console.WriteLine("It's false because <=, <, >, >= don't work on null."); 11: } To make matters even more confusing, take for example your usual check to see if something is less than, greater to, or equal: 1: int? x = null; 2: int? y = 100; 3:  4: if (x < y) 5: { 6: Console.WriteLine("X is less than Y"); 7: } 8: else if (x > y) 9: { 10: Console.WriteLine("X is greater than Y"); 11: } 12: else 13: { 14: // We fall into the "equals" assumption, but clearly null != 100! 15: Console.WriteLine("X is equal to Y"); 16: } Yes, this code outputs “X is equal to Y” because both the less-than and greater-than operators return false when a Nullable wrapped operator comparable type is null.  This violates a lot of our assumptions because we assume is something is not less than something, and it’s not greater than something, it must be equal.  So keep in mind, that the only two comparison operators that work on Nullable wrapped types where at least one is null are the equals (==) and not equals (!=) operators: 1: int? x = null; 2: int? y = 100; 3:  4: if (x == y) 5: { 6: Console.WriteLine("False, x is null, y is not."); 7: } 8:  9: if (x != y) 10: { 11: Console.WriteLine("True, x is null, y is not."); 12: } Solution: The Nullable static class So we’ve seen that <, <=, >, and >= have some interesting and perhaps unexpected behaviors that can trip up a novice developer who isn’t expecting the kinks that System.Nullable<T> types with comparison operators can throw.  How can we easily mitigate this? Well, obviously, you could do null checks before each check, but that starts to get ugly: 1: if (x.HasValue) 2: { 3: if (y.HasValue) 4: { 5: if (x < y) 6: { 7: Console.WriteLine("x < y"); 8: } 9: else if (x > y) 10: { 11: Console.WriteLine("x > y"); 12: } 13: else 14: { 15: Console.WriteLine("x == y"); 16: } 17: } 18: else 19: { 20: Console.WriteLine("x > y because y is null and x isn't"); 21: } 22: } 23: else if (y.HasValue) 24: { 25: Console.WriteLine("x < y because x is null and y isn't"); 26: } 27: else 28: { 29: Console.WriteLine("x == y because both are null"); 30: } Yes, we could probably simplify this logic a bit, but it’s still horrendous!  So what do we do if we want to consider null less than everything and be able to properly compare Nullable<T> wrapped value types? The key is the System.Nullable static class.  This class is a companion class to the System.Nullable<T> class and allows you to use a few helper methods for Nullable<T> wrapped types, including a static Compare<T>() method of the. What’s so big about the static Compare<T>() method?  It implements an IComparer compatible comparison on Nullable<T> types.  Why do we care?  Well, if you look at the MSDN description for how IComparer works, you’ll read: Comparing null with any type is allowed and does not generate an exception when using IComparable. When sorting, null is considered to be less than any other object. This is what we probably want!  We want null to be less than everything!  So now we can change our logic to use the Nullable.Compare<T>() static method: 1: int? x = null; 2: int? y = 100; 3:  4: if (Nullable.Compare(x, y) < 0) 5: { 6: // Yes! x is null, y is not, so x is less than y according to Compare(). 7: Console.WriteLine("x < y"); 8: } 9: else if (Nullable.Compare(x, y) > 0) 10: { 11: Console.WriteLine("x > y"); 12: } 13: else 14: { 15: Console.WriteLine("x == y"); 16: } Summary So, when doing math comparisons between two numeric values where one of them may be a null Nullable<T>, consider using the System.Nullable.Compare<T>() method instead of the comparison operators.  It will treat null less than any value, and will avoid logic consistency problems when relying on < returning false to indicate >= is true and so on.

  • Persistent static routes fail on MacOS 10.6.5 startup!

    - by verbalicious
    I'm unable to get static routes to persist a reboot on Mac OS 10.6.5. I've tried all of the methods prescribed in Google search results, and previous posts on this site. I've tried manually creating a launchd daemon, and used RouteSplit's launchd daemon to no avail. It's clear that the interface is not ready when these methods attempt to apply the route. This workstation in question is getting its IP from DHCP and probably hasn't gotten its DHCP lease when the command runs. We're able to apply the route by hand when logged in, but not through startup methods. Is there another way to apply this route by sneaking the command into something later, but before the login window appears to the user? Here is some relevant log info from system.log. You can see the "route: writing to routing socket: Network is unreachable" errors where my launchd script fires off. I've tried adding extra "sleep" and "ipconfig waitall" statements later in the script but this doesn't fly.

  • Is it possible to create static classes in PHP (like in C#)?

    - by aleemb
    I want to create a static class in PHP and have it behave like it does in C#, so Constructor is automatically called on the first call to the class No instantiation required Something of this sort... static class Hello { private static $greeting = 'Hello'; private __construct() { $greeting .= ' There!'; } public static greet(){ echo $greeting; } } Hello::greet(); // Hello There!

  • Why would a static inner interface be used in Java?

    - by Mo
    I have just found a static inner interface in our code-base. class Foo { public static interface Bar { /* snip */ } /* snip */ } I have never seen this before. The original developer is out of reach. Therefore I have to ask SO: What are the semantics behind a static interface? What would change, if I remove the static? Why would anyone do this?

  • Can ASM method-visitors be used with interfaces?

    - by Olaf Mertens
    I need to write a tool that lists the classes that call methods of specified interfaces. It will be used as part of the build process of a large java application consisting of many modules. The goal is to automatically document the dependencies between certain java modules. I found several tools for dependency analysis, but they don't work on the method level, just for packages or jars. Finally I found ASM, that seems to do what I need. The following code prints the method dependencies of all class files in a given directory: import java.io.*; import java.util.*; import org.objectweb.asm.ClassReader; public class Test { public static void main(String[] args) throws Exception { File dir = new File(args[0]); List<File> classFiles = new LinkedList<File>(); findClassFiles(classFiles, dir); for (File classFile : classFiles) { InputStream input = new FileInputStream(classFile); new ClassReader(input).accept(new MyClassVisitor(), 0); input.close(); } } private static void findClassFiles(List<File> list, File dir) { for (File file : dir.listFiles()) { if (file.isDirectory()) { findClassFiles(list, file); } else if (file.getName().endsWith(".class")) { list.add(file); } } } } import org.objectweb.asm.MethodVisitor; import org.objectweb.asm.commons.EmptyVisitor; public class MyClassVisitor extends EmptyVisitor { private String className; @Override public void visit(int version, int access, String name, String signature, String superName, String[] interfaces) { this.className = name; } @Override public MethodVisitor visitMethod(int access, String name, String desc, String signature, String[] exceptions) { System.out.println(className + "." + name); return new MyMethodVisitor(); } } import org.objectweb.asm.commons.EmptyVisitor; public class MyMethodVisitor extends EmptyVisitor { @Override public void visitMethodInsn(int opcode, String owner, String name, String desc) { String key = owner + "." + name; System.out.println(" " + key); } } The Problem: The code works for regular classes only! If the class file contains an interface, visitMethod is called, but not visitMethodInsn. I don't get any info about the callers of interface methods. Any ideas?

  • Calling overridden parent method from parent method

    - by Yisroel
    Heres the situation. Component B extends component A and overrides the init method to accept a different parameter. A also has a create method that calls init. If i have an instance of B and i call create, its calling the wrong init - it calls init in B, where i need it to call init in A. I dont want to call super.init() as there may not always be a super. Is there any way to specify to call the init in the parent component?

  • Will this static class break in a multi user scenario ?

    - by Perpetualcoder
    Say I make a static class like following with an extension method: public static class MyStaticExtensionClass { private static readonly Dictionary<int, SomeClass> AlgoMgmtDict = new Dictionary<int, SomeClass>(); public static OutputClass ToOutput(this InputClass input) { // clears up the dict // does some kind of transform over the input class // return an OutputClass object } } In a multi user system, will the state management dictionary fail to provide correct values for the transform algorithm? Will a regular class be a better design or shoving the Dictionary inside the method a better design?

  • When is a parameterized method call useful?

    - by johann-christoph-jacob
    A Java method call may be parameterized like in the following code: class Test { <T> void test() { } public static void main(String[] args) { new Test().<Object>test(); // ^^^^^^^^ } } I found out this is possible from the Eclipse Java Formatter settings dialog and wondered if there are any cases where this is useful or required.

  • Would the instance reference parameters passed into the static methods get garbage collected?

    - by 123Developer
    I know that the static objects in .Net managed world are loaded in Loader Heap which is never going to be garbage collected. What happens to the instance reference parameters passed to a static methods. Are they get garbage collected once the static function executed completely Or they are going to live forever as those instance reference variables are once passed to static method? I am really confused this evening; Please guide me. Thanks and regards 123Developer.

  • Can we call methods of non-static classes without an object in Java?

    - by ask
    In Java, the wrapper class Integer has the static method parseInt() which is used like this: Integer.parseInt(). I thought only methods of static classes could be called like this (ie. Class.doMethod()). All non-static classes need objects to be instantiated to use their methods. I checked the API, and apparently Integer is declared as public final Integer - not static. Someone please help me understand this.

  • best alternative to in-definition initialization of static class members? (for SVN keywords)

    - by Jeff
    I'm storing expanded SVN keyword literals for .cpp files in 'static char const *const' class members and want to store the .h descriptions as similarly as possible. In short, I need to guarantee single instantiation of a static member (presumably in a .cpp file) to an auto-generated non-integer literal living in a potentially shared .h file. Unfortunately the language makes no attempt to resolve multiple instantiations resulting from assignments made outside class definitions and explicitly forbids non-integer inits inside class definitions. My best attempt (using static-wrapping internal classes) is not too dirty, but I'd really like to do better. Does anyone have a way to template the wrapper below or have an altogether superior approach? // Foo.h: class with .h/.cpp SVN info stored and logged statically class Foo { static Logger const verLog; struct hInfoWrap; public: static hInfoWrap const hInfo; static char const *const cInfo; }; // Would like to eliminate this per-class boilerplate. struct Foo::hInfoWrap { hInfoWrapper() : text("$Id$") { } char const *const text; }; ... // Foo.cpp: static inits called here Foo::hInfoWrap const Foo::hInfo; char const *const Foo::cInfo = "$Id$"; Logger const Foo::verLog(Foo::cInfo, Foo::hInfo.text); ... // Helper.h: output on construction, with no subsequent activity or stored fields class Logger { Logger(char const *info1, char const *info2) { cout << info0 << endl << info1 << endl; } }; Is there a way to get around the static linkage address issue for templating the hInfoWrap class on string literals? Extern char pointers assigned outside class definitions are linguistically valid but fail in essentially the same manner as direct member initializations. I get why the language shirks the whole resolution issue, but it'd be very convenient if an inverted extern member qualifier were provided, where the definition code was visible in class definitions to any caller but only actually invoked at the point of a single special declaration elsewhere. Anyway, I digress. What's the best solution for the language we've got, template or otherwise? Thanks!

  • Java method keyword "final" and its use

    - by Lukas Eder
    When I create complex type hierarchies (several levels, several types per level), I like to use the final keyword on methods implementing some interface declaration. An example: interface Garble { int zork(); } interface Gnarf extends Garble { /** * This is the same as calling {@link #zblah(0)} */ int zblah(); int zblah(int defaultZblah); } And then abstract class AbstractGarble implements Garble { @Override public final int zork() { ... } } abstract class AbstractGnarf extends AbstractGarble implements Gnarf { // Here I absolutely want to fix the default behaviour of zblah // No Gnarf shouldn't be allowed to set 1 as the default, for instance @Override public final int zblah() { return zblah(0); } // This method is not implemented here, but in a subclass @Override public abstract int zblah(int defaultZblah); } I do this for several reasons: It helps me develop the type hierarchy. When I add a class to the hierarchy, it is very clear, what methods I have to implement, and what methods I may not override (in case I forgot the details about the hierarchy) I think overriding concrete stuff is bad according to design principles and patterns, such as the template method pattern. I don't want other developers or my users do it. So the final keyword works perfectly for me. My question is: Why is it used so rarely in the wild? Can you show me some examples / reasons where final (in a similar case to mine) would be very bad?
