  • jquery 'this' confusion

    - by Elliott
    Hi I have the code below, once the first (only) item in the menu is hovered over, the subtext should appear. I have used 'this' as I thought it should find the class with the "li" and then slideDown. This doesnt seem to work, although 'this' works for when you remove the hover, as it slides up (top part not the subtext). <body> <script type="text/javascript"> $(document).ready(function() { $('li').hover(function() { $(this).stop(true, true).slideDown(); $(this).slideDown("slow"); }, function () { $(this).slideUp("fast"); } ); }); </script> <ul> <li class="hover"> <p><a href="#">Hover</a></p> <p class="subtext">Show More</p> </li> </ul> Any advice? Thanks

  • Jquery autocomplete webservices - what am i doing wrong??

    - by dzajdol
    I created a class for JSON responses: public class PostCodeJson { public String Text { get; private set; } public String Value { get; private set; } #region Constructors /// <summary> /// Empty constructor /// </summary> public PostCodeJson() { this.Text = String.Empty; this.Value = String.Empty; } /// <summary> /// Constructor /// </summary> /// <param name="_text"></param> /// <param name="_value"></param> public PostCodeJson(String _text, String _value) { this.Text = _text; this.Value = _value; } #endregion Constructors } and function returns list of this class using in webservices method: [WebMethod] public List<PostCodeJson> GetPostCodesCompletionListJson(String prefixText, Int32 count) { return LibDataAccess.DBServices.PostCodes.GetPostCodeJson(prefixText, count); } And in aspx i do this that: <script> $(document).ready(function() { $("#<%=pc.ClientID %>").autocomplete( baseUrl + "WebServices/Autocomplete.asmx/GetPostCodesCompletionListJson", { parse: function(data) { var array = new Array(); for (var i = 0; i < data.length; i++) { var datum = data[i]; var name = datum.Text; var display = name; array[array.length] = { data: datum, value: display, result: datum.Value }; } return array; }, dataType: "xml" }); }); </script> and when you enter something in the box i got an error: Request format is unrecognized for URL unexpectedly ending in '/GetPostCodesCompletionListJson What am I doing wrong??

  • Consistent Equals() results, but inconsistent TreeMap.containsKey() result

    - by smessing
    I have the following object Node: private class Node implements Comparable<Node>(){ private String guid(); ... public boolean equals(Node o){ return (this == o); } public int hashCode(){ return guid.hashCode(); } ... } And I use it in the following TreeMap: TreeMap<Node, TreeSet<Edge>> nodes = new TreeMap<Node, TreeSet<Edge>>(); Now, the tree map is used in a class called Graph to store nodes currently in the graph, along with a set of their edges (from the class Edge). My problem is when I try to execute: public containsNode(n){ for (Node x : nodes.keySet()) { System.out.println("HASH CODE: "); System.out.print(x.hashCode() == n.hashCode()); System.out.println("EQUALS: "); System.out.print(x.equals(n)); System.out.println("CONTAINS: "); System.out.print(nodes.containsKey(n)); System.out.println("N: " + n); System.out.println("X: " + x); } } I sometimes get the following: HASHCODE: true EQUALS: true CONTAINS: false N: foo X: foo Anyone have an idea as to what I'm doing wrong? I'm still new to all this, so I apologize in advance if I'm overlooking something simple (I know hashCode() doesn't really matter for TreeMap, but I figured I'd include it).

  • Problems when handling orientation changes

    - by nixau
    Hi all, I need to handle orientation changes in my Android application. For this purpose I decided to use OrientationEventListener convenience class. But his callback method is given somewhat strange behavior. My application starts in the portrait mode and then eventually switches to the lanscape one. I have some custom code executing in the callback onOrientationChanged method that provides some additional UI handling logic - it has a few calls to findViewById. What is strange is that when switching back from landscape to portrait mode onOrientationChanged callback is called twice, and what's even worse - the second call is dealing with bad Context - findViewById method starts returning null. These calls are made right from the MainThread @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); listener = new OrientationListener(); } @Override protected void onResume() { super.onResume(); // enabling listening listener.enable(); } @Override protected void onPause() { super.onPause(); // disabling listening listener.disable(); } I've replicated the same behavior with a dummy Activity without any logic except for one that deals with orientation hadling. I initiate orientation switch from the Android 2.2 emulator by pressing Ctrl+F11 What could be wrong? Upd: Inner class that implements OrientationEventListener private class OrientationListener extends OrientationEventListener { public OrientationL() { super(getBaseContext()); } @Override public void onOrientationChanged(int orientation) { toString(); } } }

  • Colour manipulation of custom tags in niceEdit HTML editor ( JS / DOM )

    - by Chris
    Hi, I would like to be able to highlight, during typing and in real time, certain custom tags in the format #tag_name# within the text of a nicEdit instance ( http://nicedit.com/ ). My current attempt to implement as close to this as possible revolves around using the blur event of the editor to highlight the tags once the editor loses focus. I then use the following logic to wrap the tags in a span with a highlight class.. htmlEditor.addEvent( "blur", function( ) { str = nicEditors.findEditor( "html_content" ).getContent( ); // Remove existing spans first, leaving just the tag ( this could mess up if the html has been edited directly ) str = str.replace( /(<span class=\"highlight\">)(.[^<]+)(<\/span>)/gi, "$2" ); // Then wrap all instances of a particular tag with the highlight span str = str.replace( /#tag_name#/gi, "<span class='highlight'>#tag_name#</span>" ); nicEditors.findEditor( "html_content" ).setContent( str ); }); This is not ideal as my actual text now contains unwanted spans ( I only want the highlighting for the user's input experience, not to be saved to the database ). Obviously I could remove the spans before saving the text but the whole system is currently open to errors ( If the html is directly edited then other text may get highlighted etc ). What I would like to know is.. Is there any way to directly change the colour of the tags in the editor or DOM without using a mechanism such as this? Perhaps a way of colouring the text in memory rather than changing the HTML ? Any ideas ? Regards Chris P

  • Get notified when objective-c dom updates are ready initiated from webview

    - by Josh
    I am programmatically updating the DOM on a WebKit webview via DOMElement objects - for complex UI, there is usually a javascript component to any element that I add. This begs the need to be notified when the updates complete -- is there any such event? I know regular divs dont fire an onload or onready event, correct? The other assumption I had, which may be totally wrong, is that DOMElement updates aren't synchronous, so I can't do something like this and be confident it will meet with the label actually in the DOM: DOMElement *displayNameLabel = [document createElement:@"div"]; [displayNameLabel setAttribute:@"class" value:@"user-display-name"]; [displayNameLabel setTextContent:currentAvatar.avatarData.displayName]; [[document getElementById:@"user-card-content"] appendChild:displayNameLabel]; id win = [webView windowScriptObject]; [win evaluateWebScript:@"javascriptInstantiateLabel()"]; Is this true? I am using jquery within the body of the html already, so I don't mind subscribing to a particular classes set of events via "live." I thought I might be able to do something like: $(".some-class-to-be-added-later").live( "ready", function(){ // Instantiate some fantastic javascript here for .some-class }); but have experienced no joy so far. Is there any way on either side (objective-c since I don't programmatically firing javascript post load, or javascript) to be notified when the element is in the DOM? Thanks, Josh

  • UIViewController remaining

    - by Guy
    Hi Guys. I have a UIViewController named equationVC who's user interface is being programmatically created from another NSObject class called equationCon. Upon loading equationVC, a method called chooseInterface is called from the equationCon class. I have a global variable (globalVar) that points to a user defined string. chooseInterface finds a method in the equationCon class that matches the string globalVar points to. In this case, let's say that globalVar points to a string that is called "methodThatMatches." In methodThatMatches, another view controller needs to show the results of what methodThatMatches did. methodThatMatches creates a new equationVC that calls upon methodThatMatches2. As a test, each method changes the color of the background. When the application starts up, I get a purple background, but as soon as I hit backwards I get another purple screen, which should be yellow. I do not think that I am release the view properly. Can anyone help? -(void)chooseInterface { NSString* equationTemp = [globalVar stringByReplacingOccurrencesOfString:@" " withString:@""]; equationTemp = [equationTemp stringByReplacingOccurrencesOfString:@"'" withString:@""]; SEL equationName = NSSelectorFromString(equationTemp); NSLog(@"selector! %@",NSStringFromSelector(equationName)); if([self respondsToSelector:equationName]){ [self performSelector:equationName]; } } -(void)methodThatMatches{ self.equationVC.view.backgroundColor = [UIColor yellowColor]; [setGlobalVar:@"methodThatMatches2"]; EquationVC* temp = [[EquationVC alloc] init]; [[self.equationVC navigationController] pushViewController:temp animated:YES ]; [temp release]; } -(void)methodThatmatches2{ self.equationVC.view.backgroundColor = [UIColor purpleColor]; }

  • Manipulating collections & the ViewModel pattern

    - by Kragen
    I'm relatively new to WPF, and I'm having trouble with what I'm fairly certain is a relatively simple problem. I have my underlying data object, a Person: class Person { public string Surname {get; set; } public string Firstname {get; set; } public List<Address> Addresses {get; } } And I wish to display and edit this object in my WPF app. To this end I've created a ViewModel that I bind to in my xaml: class PersonViewModel { public string Fullname {get; } public ObservableCollection<AddressViewModel> Addresses {get; } } This is fine, except when it comes to manipulating my Address collection, where I can't work out what I should be doing: Should I add methods AddAddress, RemoveAddress etc... to my PersonViewModel class for manipulating my collection with instances of AddressViewModel Should I just add instances of AddressViewModel to my Addresses observable collection Both of the above seem a bit messy - is there a better way of dealing with collections?

  • Simple Java Applet not loading in FireFox / Safari on MacOS

    - by Sleepless
    Hello all, I'm probably missing something very basic here. I'm trying to get my first applet to run inside a local HTML page in Firefox 3.6 on Mac OS 10.5.8. Here's the applet's code: package SimpleApplet; import java.applet.Applet; import java.awt.*; public class MyApplet extends Applet { private static final long serialVersionUID = 1L; public void init() { } public void stop() { } public void paint(Graphics g) { g.drawString("Tweedle-Dee!",20,40); } } Here's the HTML page: <html> <body> Here's the applet: <br/> <applet code="MyApplet.class" width="300" height="150"> </applet> </body> </html> Both files (.class and .html) are in the same folder on my local machine. Now when I load the .html file into Firefox, a rectangle with a red X gets displayed. The applet works when started from Eclipse (using JRE 1.5 BTW). Also, it's not a general problem with my browser, as several pages with applets (e.g. http://java.sun.com/applets/jdk/1.4/demo/applets/Blink/example1.html) work. This is also difficult to troubleshoot because there is no output at all on the Java console... Any suggestions are appreciated!

  • Scrollbar with Sprite and Rectangle won't move text, just the Rectangle it's painted on.

    - by WebDevHobo
    Warning: school assignment. For those of you still with me, I am tasked with making some scrollable content in Flash. Load in a TextFile using LoadURL(), then display it. To get the text, we've written our own class TextFieldExtended, which is basically just there to give the textfile location to the constructor and then have the class do the various steps of getting it and loading it for you. So I needed to get a Scrollbar, which I got here: http://kirupa.com/forum/showthread.php?t=245468 (all files in a zip linked at the end of this text) The thing is, it works with Sprites. After trying to get it to accept TextFieldExtended, I bumped into a block, since the scrollbar relied heavily on a Sprite property that TextFieldExtended didn't have or could have. So I tried adding the TextFieldExtended instance to a Sprite instance using addchild. A problem occurs here that I do not know how to handle. It seems that a Rectangle is drawn and the Text is drawn on that. I say this because the scrollbar moves the Rectangle up and down a bit, but the text doesn't scroll, just the Rectangle it is positioned in and the text then moves along with it. My question: can this be fixed, or is does this implementation of scrollbars need a lot of adaptations before this is possible? If so, any scrollbars you can recommend, because it's too extended for me at this point. All files: http://www.mediafire.com/?q2ium22gmox This was made in Flash CS4 using ActionScript3. The Example class is the final implementation

  • Android maps out of memory error

    - by SamB09
    Hi , sometimes when running a google maps program with an overlay image i will receive a bit map out of memory error.

  • Unable to run jQuery Masonry in a Sencha Touch 2 app

    - by torr
    In my ST2 app I have on index.html <script id="jquery" type="text/javascript" src="resources/js/jquery-1.8.2.js"></script> <script id="masonry" type="text/javascript" src="resources/js/masonry-2.1.5.js"></script> as well as <script> $(document).ready(function(){ var $container = $('.x-list-container'); $container.imagesLoaded(function(){ $container.masonry({ itemSelector: '.x-list-item', }); }); }); </script> My front page on the app is a list so it wraps elements as such <div class="x-list-container"> <div class="x-list-item"></div> // 'x-list-item' is the block I want to float <div class="x-list-item"></div> ... </div> However once everything is loaded and I inspect .x-list-item there is no style positioning the div. I am experience with Masonry on regular web app but can;t make it work here. It's like Masonry isn't running at all. It is being loaded (checked on the network tab) and jQuery is being loaded (on network tab and tested using if (jQuery) {alert('hey there');. Any idea what I'm doing wrong? }

  • Initial text and paperclipped-URL for action in UIActivityViewController & UIActivityItemSource?

    - by Benjamin Kreeger
    Finally been making it through Apple's (rather dismal) documentation on the new UIActivityViewController class and the UIActivityItemSource protocol, and I'm trying to send different data sets to different actions called from the activity view. To simplify things, I'm looking at two things. A Facebook posting action, which should say "Check this out!" and also attach a URL to the post (with that cute little paperclip). A Twitter posting action, which should say "Check this out, with #hashtag!" and also attach that same URL (with the same paperclip). Here's the code I've got implemented right now. - (id)activityViewController:(UIActivityViewController *)activityViewController itemForActivityType:(NSString *)activityType { if ([activityType isEqualToString:UIActivityTypePostToFacebook]) { return @"Check this out!"; } else if ([activityType isEqualToString:UIActivityTypePostToTwitter]) { return @"Check this out, with #hashtag!"; } return @""; } - (id)activityViewControllerPlaceholderItem:(UIActivityViewController *)activityViewController { return @""; } And then when I set up this activity view controller (it's in the same class), this is what I do. UIActivityViewController *activityView = [[UIActivityViewController alloc] initWithActivityItems:@[self] applicationActivities:nil]; [self presentViewController:activityView animated:YES completion:nil]; My dilemma is how to attach that NSURL object. It's relatively easy when calling the iOS 6 SL-class posting modals; you just call the individual methods to attach a URL or an image. How would I go about doing this here? I'll note that instead of returning NSString objects from -activityViewController:itemForActivityType, if I return just NSURL objects, they show up with that paperclip, with no body text in the post. If I return an array of those two items, nothing shows up at all.

  • Website --> Add Reference also creates files with pdb extensions

    - by SourceC
    Hello, Q1 Any assemblies stored in Bin directory will automatically be referenced by web application. We can add assembly reference via Website -- Add Reference or simply by copying dll into Bin folder. But I noticed that when we add reference via Website -- Add Reference, that additional files with .pdb extension are placed inside Bin. If these files are also needed, then why does reference still work even if we only place referenced dll into Bin, but not pdb files Q2 It appears that if you add a new item to web project, this class will automatically be added to project list and we can reference it from all pages in this project. So are all files added to project list automatically being referenced ? thanx EDIT: On your second question, you are adding a public class to a namespace so will be visible to other classes in that project and in that namespace. I don’t know much about assemblies, but I’d assume the reason why item( class ) added to the project is visible to other classes in that project is for the simple fact that in web project all classes get compiled into single assembly and for the fact that public classes contained in the same assembly are always visible to each other? much appreciated

  • Email Collector / Implementation

    - by Tian
    I am implementing a simple RoR webpage that collect emails from visitors and store them as objects. I'm using it as a mini-project to try RoR and BDD. I can think of 3 features for Cucumber: 1. User submits a valid email address 2. User submits an existing email address 3. User submits an invalid email My question is, for scenarios 2 and 3, is it better to handle this via the controller? or as methods in a class? Perhaps something that throws errors if an instance is instantiated in sceanrio 2 or 3? Implementation is below, love to hear some code reviews in addition to answers to questions above. Thanks!

  • Getting exception when trying to monkey patch pymongo.connection._Pool

  • How to poll a file in /sys

    Hi, I am stuck reading a file in /sys/ which contains the light intensity in Lux of the ambient light sensor on my Nokia N900 phone. See thread on talk.maemo.org here I tried to use pyinotify to poll the file but this looks some kind of wrong to me since the file is alway "process_IN_OPEN", "process_IN_ACCESS" and "process_IN_CLOSE_NOWRITE" I basically want to get the changes ASAP and if something changed trigger an event, execute a class... Here's the code I tried, which works, but not as I expected (I was hoping for process_IN_MODIFY to be triggered): #!/usr/bin/env python # -*- coding: utf-8 -*- # import os, time, pyinotify import pyinotify ambient_sensor = '/sys/class/i2c-adapter/i2c-2/2-0029/lux' wm = pyinotify.WatchManager() # Watch Manager mask = pyinotify.ALL_EVENTS def action(self, the_event): value = open(the_event.pathname, 'r').read().strip() return value class EventHandler(pyinotify.ProcessEvent): def process_IN_ACCESS(self, event): print "ACCESS event:", action(self, event) def process_IN_ATTRIB(self, event): print "ATTRIB event:", action(self, event) def process_IN_CLOSE_NOWRITE(self, event): print "CLOSE_NOWRITE event:", action(self, event) def process_IN_CLOSE_WRITE(self, event): print "CLOSE_WRITE event:", action(self, event) def process_IN_CREATE(self, event): print "CREATE event:", action(self, event) def process_IN_DELETE(self, event): print "DELETE event:", action(self, event) def process_IN_MODIFY(self, event): print "MODIFY event:", action(self, event) def process_IN_OPEN(self, event): print "OPEN event:", action(self, event) #log.setLevel(10) notifier = pyinotify.ThreadedNotifier(wm, EventHandler()) notifier.start() wdd = wm.add_watch(ambient_sensor, mask) wdd time.sleep(5) notifier.stop() Thanks for any hints, suggestions and examples Kind regards Bjoern

  • Avoiding anemic domain model - a real example

    - by cbp
    I am trying to understand Anemic Domain Models and why they are supposedly an anti-pattern. Here is a real world example. I have an Employee class, which has a ton of properties - name, gender, username, etc public class Employee { public string Name { get; set; } public string Gender { get; set; } public string Username { get; set; } // Etc.. mostly getters and setters } Next we have a system that involves rotating incoming phone calls and website enquiries (known as 'leads') evenly amongst sales staff. This system is quite complex as it involves round-robining enquiries, checking for holidays, employee preferences etc. So this system is currently seperated out into a service: EmployeeLeadRotationService. public class EmployeeLeadRotationService : IEmployeeLeadRotationService { private IEmployeeRepository _employeeRepository; // ...plus lots of other injected repositories and services public void SelectEmployee(ILead lead) { // Etc. lots of complex logic } } Then on the backside of our website enquiry form we have code like this: public void SubmitForm() { var lead = CreateLeadFromFormInput(); var selectedEmployee = Kernel.Get<IEmployeeLeadRotationService>() .SelectEmployee(lead); Response.Write(employee.Name + " will handle your enquiry. Thanks."); } I don't really encounter many problems with this approach, but supposedly this is something that I should run screaming from because it is an Anemic Domain Model. But for me its not clear where the logic in the lead rotation service should go. Should it go in the lead? Should it go in the employee? What about all the injected repositories etc that the rotation service requires - how would they be injected into the employee, given that most of the time when dealing with an employee we don't need any of these repositories?

  • How to MakeTable ReadOnly including contents like images

    - by GustlyWind
    I have a table which has two text boxes and a image beside it to click and open a popup. In read-only mode based on condition I am able to make text boxes read-only but images are not becoming read-only.One solution I had is the anchor tag associated with image calls for JavaScript where I can check for a dummy click when it is in read-only mode. The problem here is the function is common and effects everywhere. So is there a way to make the entire table read-only so that no extra workaround needs to done. Edited for code <table> <tr> <td class="lightbg" colspan='4'>&nbsp; Expires:<input type="TEXT" value="" id="element1" name="expireDate" size="10" maxlength="20" class="" onChange="javascript:validateDateEntry('element1',true);;"> Period:<input type="TEXT" value="" id="element2" name="refershDate" size="10" maxlength="20" class="" onChange="javascript:validateDateEntry('element2',true);;"> &nbsp; <a href="javascript:doCalendar('element1');"> <img src="/PWM/images/images_2006/calendarbtn.gif" border="0" alt="Click to select date from calendar" align="absmiddle"> </a> </td> </tr> <tr> <td colspan='4'><b>*</b>Times are in the WFM Server's Time Zone.</td></tr> </table> Thanks

Please note Resource1.stringXml = its coming from resource file.If i pass strelemet.outerXMl i get the object from Deserialize object ,but if i pass Resource1.stringXml i am getting following exception {"< STRING xmlns='' was not expected."} System.Exception {System.InvalidOperationException} class Program { static void Main(string[] args) { StringResource str = new StringResource(); str.DELETE = "CanDelete"; str.ID= "23342"; XmlElement strelemet = SerializeObjectToXmlNode (str); StringResource strResourceObject = DeSerializeXmlNodeToObject<StringResource>(Resource1.stringXml); Console.ReadLine(); } public static T DeSerializeXmlNodeToObject<T>(string objectNodeOuterXml) { try { TextReader objStringsTextReader = new StringReader(objectNodeOuterXml); XmlSerializer stringResourceSerializer = new XmlSerializer(typeof(T),string.Empty); return (T)stringResourceSerializer.Deserialize(objStringsTextReader); } catch (Exception excep) { return default(T); } } public static XmlElement SerializeObjectToXmlNode(object obj) { using (MemoryStream memoryStream = new MemoryStream()) { try { XmlSerializerNamespaces xmlNameSpace = new XmlSerializerNamespaces(); xmlNameSpace.Add(string.Empty, string.Empty); XmlWriterSettings writerSettings = new XmlWriterSettings(); writerSettings.CloseOutput = false; writerSettings.Encoding = System.Text.Encoding.UTF8; writerSettings.Indent = false; writerSettings.OmitXmlDeclaration = true; XmlWriter writer = XmlWriter.Create(memoryStream, writerSettings); XmlSerializer xmlserializer = new XmlSerializer(obj.GetType()); xmlserializer.Serialize(writer, obj, xmlNameSpace); writer.Close(); memoryStream.Position = 0; XmlDocument serializeObjectDoc = new XmlDocument(); serializeObjectDoc.Load(memoryStream); return serializeObjectDoc.DocumentElement; } catch (Exception excep) { return null; } } } } public class StringResource { [XmlAttribute] public string DELETE; [XmlAttribute] public string ID; }

  • ASP.NET MVC UpdateModel doesn't update inherited public properties??

    - by mrjoltcola
    I refactored some common properties into a base class and immediately my model updates started failing. UpdateModel() and TryUpdateModel() do not seem to update inherited public properties. I cannot find detailed info on MSDN nor Google as to the rules or semantics of these methods. The docs are terse (http://msdn.microsoft.com/en-us/library/dd470933.aspx), simply stating: Updates the specified model instance using values from the controller's current value provider. Well that leads us to believe it is as simple as that. It makes no mention of limitations with inheritance. My assumption is the methods are reflecting on the top class only, ignoring base properties, but this seems to be an ugly shortcoming, if so. SOLVED: Eep, this turned out to have nothing to do with inheritance. My base class was implemented with public fields, not properties. Switching them to formal properties (adding {get; set; }) was all I needed. This has bitten me before, I keep wanting to use simple, public fields.

  • jsTree: How to create a new ID for the new added node?

    - by marknt15
    Hi, I can normally get the ID of the default tree nodes but my problem is onCreate then jsTree will add a new node but it doesn't have an ID. My question is how can I add an ID to the newly created tree node? What I'm thinking to do is adding the ID HTML attribute to the newly created tree node but how? I need to get the ID of all of the nodes because it will serve as a reference for the node's respective div storage. HTML code: <div class="demo" id="demo_1"> <ul> <li id="phtml_1" class="file"><a href="#"><ins>&nbsp;</ins>Root node 1</a></li> <li id="phtml_2" class="file"><a href="#"><ins>&nbsp;</ins>Root node 2</a></li> </ul> </div> JS code: $("#demo_1").tree({ ui : { theme_name : "apple" }, callback : { onrename : function (NODE, TREE_OBJ) { alert(TREE_OBJ.get_text(NODE)); alert($(NODE).attr('id')); } } }); Cheers, Mark

  • How to TDD Asynchronous Events?

    - by Padu Merloti
    The fundamental question is how do I create a unit test that needs to call a method, wait for an event to happen on the tested class and then call another method (the one that we actually want to test)? Here's the scenario if you have time to read further: I'm developing an application that has to control a piece of hardware. In order to avoid dependency from hardware availability, when I create my object I specify that we are running in test mode. When that happens, the class that is being tested creates the appropriate driver hierarchy (in this case a thin mock layer of hardware drivers). Imagine that the class in question is an Elevator and I want to test the method that gives me the floor number that the elevator is. Here is how my fictitious test looks like right now: [TestMethod] public void TestGetCurrentFloor() { var elevator = new Elevator(Elevator.Environment.Offline); elevator.ElevatorArrivedOnFloor += TestElevatorArrived; elevator.GoToFloor(5); //Here's where I'm getting lost... I could block //until TestElevatorArrived gives me a signal, but //I'm not sure it's the best way int floor = elevator.GetCurrentFloor(); Assert.AreEqual(floor, 5); } Edit: Thanks for all the answers. This is how I ended up implementing it: [TestMethod] public void TestGetCurrentFloor() { var elevator = new Elevator(Elevator.Environment.Offline); elevator.ElevatorArrivedOnFloor += (s, e) => { Monitor.Pulse(this); }; lock (this) { elevator.GoToFloor(5); if (!Monitor.Wait(this, Timeout)) Assert.Fail("Elevator did not reach destination in time"); int floor = elevator.GetCurrentFloor(); Assert.AreEqual(floor, 5); } }

  • 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?
