  • How do I implement multiple kinds of an object in OOP?

    - by Jeremy Rudd
    I have multiple kinds of an object, say Car for example. Do I have each kind in an inherited class/subclass of Car? Do I place these under a cartype namespace so as not to mess up the main namespace? Then later when I need an array of cars, should I declare it as var currentCars():Car or var currentCars():Object? Would the former support any subclass of Car?

  • Split with token info

    - by boomhauer
    I would like to split a string using multiple chars to split upon. For example, consider spin text format: This is a {long|ugly|example} string I would want to parse this string and split it on the "{", "|", and "}" chars myString.Split('|','{','}') Now I have tokens to play with, but what I would like is to retain the info about which char was used to split each piece of the array that is returned. Any existing code that can do something like this?

  • Initialize virtual attributes

    - by Horace Loeb
    I have an IncomingEmail model with an attachments virtual attribute: class IncomingEmail < ActiveRecord::Base attr_accessor :attachments end I want the attachments virtual attribute to be initialized to [] rather than nil so that I can do: >> i = IncomingEmail.new => #<IncomingEmail id: nil,...) >> i.attachments << "whatever" Without first setting i.attachments to [] (put another way, I want this virtual attribute to default to an empty array rather than nil)

  • Coloring NSTableView Text per row

    - by Tristan
    I have a NSTableView that is displaying an array of objects I have. For each of these objects (rows) I would like to change the color of the text displayed depending on the results of a function I run on each object; So for example all the object in the table that exist in another list (or some other requirement) I want to display them in green text, and objects that don't exist display in red. How would I go about doing this?

  • jQuery.extend() not giving deep copy of object formed by constructor

    - by two7s_clash
    I'm trying to use this to clone a complicated Object. The object in question has a property that is an array of other Objects, and each of these have properties of different types, mostly primitives, but a couple further Objects and Arrays. For example, an ellipsed version of what I am trying to clone: var asset = new Assets(); function Assets() { this.values = []; this.sectionObj = Section; this.names = getNames; this.titles = getTitles; this.properties = getProperties; ... this.add = addAsset; function AssetObj(assetValues) { this.name = ""; this.title = ""; this.interface = ""; ... this.protected = false; this.standaloneProtected = true; ... this.chaptersFree = []; this.chaptersUnavailable = []; ... this.mediaOptions = { videoWidth: "", videoHeight: "", downloadMedia: true, downloadMediaExt: "zip" ... } this.chaptersAvailable = []; if (typeof assetValues == "undefined") { return; } for (var name in assetValues) { if (typeof assetValues[name] == "undefined") { this[name] = ""; } else { this[name] = assetValues[name]; } } ... function Asset() { return new AssetObj(); } ... function getProperties() { var propertiesArray = new Array(); for (var property in this.values[0]) { propertiesArray.push(property); } return propertiesArray; } ... function addAsset(assetValues) { var newValues; newValues = new AssetObj(assetValues); this.values.push(newValues); } } When I do var copiedAssets = $.extend(true, {}, assets); copiedAssets.values == [], while assets.values == [Object { name="section_intro", more...}, Object { name="select_textbook", more...}, Object { name="quiz", more...}, 11 more...] When I do var copiedAssets = $.extend( {}, assets); all copiedAssets.values.[X].properties are just pointers to the value in assets. What I want is a true deep copy all the way down. What am I missing? Do I need to write a custom extend function? If so, any recommended patterns?

  • Understanding WebRequest

    - by Nai
    I found this snippet of code here that allows you to log into a website and get the response from the logged in page. However, I'm having trouble understanding all the part of the code. I've tried my best to fill in whatever I understand so far. Hope you guys can fill in the blanks for me. Thanks string nick = "mrbean"; string password = "12345"; //this is the query data that is getting posted by the website. //the query parameters 'nick' and 'password' must match the //name of the form you're trying to log into. you can find the input names //by using firebug and inspecting the text field string postData = "nick=" + nick + "&password=" + password; // this puts the postData in a byte Array with a specific encoding //Why must the data be in a byte array? byte[] data = Encoding.ASCII.GetBytes(postData); // this basically creates the login page of the site you want to log into WebRequest request = WebRequest.Create("http://www.mrbeanandme.com/login/"); // im guessing these parameters need to be set but i dont why? request.Method = "POST"; request.ContentType = "application/x-www-form-urlencoded"; request.ContentLength = data.Length; // this opens a stream for writing the post variables. // im not sure what a stream class does. need to do some reading into this. Stream stream = request.GetRequestStream(); // you write the postData to the website and then close the connection? stream.Write(data, 0, data.Length); stream.Close(); // this receives the response after the log in WebResponse response = request.GetResponse(); stream = response.GetResponseStream(); // i guess you need a stream reader to read a stream? StreamReader sr = new StreamReader(stream); // this outputs the code to console and terminates the program Console.WriteLine(sr.ReadToEnd()); Console.ReadLine();

  • How do I use data from the main window in a sub-window?

    - by eagle
    I've just started working on a photo viewer type desktop AIR app with Flex. From the main window I can launch sub-windows, but in these sub-windows I can't seem to access the data I collected in the main window. How can I access this data? Or, how can I send this data to the sub-window on creation? It doesn't need to be dynamically linked. myMain.mxml <?xml version="1.0" encoding="utf-8"?> <s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" width="260" height="200" title="myMain"> <fx:Declarations> </fx:Declarations> <fx:Script> <![CDATA[ public function openWin():void { new myWindow().open(); } public var myData:Array = new Array('The Eiffel Tower','Paris','John Doe'); ]]> </fx:Script> <s:Button x="10" y="10" width="240" label="open a sub-window" click="openWin();"/> </s:WindowedApplication> myWindow.mxml <?xml version="1.0" encoding="utf-8"?> <mx:Window name="myWindow" title="myWindow" xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" width="640" height="360"> <mx:Script> <![CDATA[ ]]> </mx:Script> <mx:Label id="comment" x="10" y="10" text=""/> <mx:Label id="location" x="10" y="30" text=""/> <mx:Label id="author" x="10" y="50" text=""/> </mx:Window> I realize this might be a very easy question but I have searched the web, read and watched tutorials on random AIR subjects for a few days and couldn't find it. The risk of looking like a fool is worth it now, I want to get on with my first app!

  • Error implementing Dynamic Tab with ListView within each Tab - Tabs don't show up

    - by Jon
    I am trying to create a dyanmic tab application that has tabs on the left for each type of Food (e.g. Pasta, Dairy, etc. including those dynamically defined by user) and for each tab, have a listview connected to a SQLite database that updates. This is in the onCreate method: setContentView(R.layout.foodCabinet_layout); dbHelper = new FoodStorageDBHelper(this); dbHelper.open(); Cursor foodTypes = dbHelper.getAllFoodTypes(); ArrayList<String> typeOfFood = new ArrayList<String>(); typeOfFoods.add(foodTypes.getString(1)); while(foodTypes.moveToNext()){ typeOfFoods.add(foodTypes.getString(1)); } final TabHost tbh = (TabHost)findViewById(R.id.food_tabhost_cabinet); tbh.setup(); for(final String s : typeOfFood){ TabSpec nts = tbh.newTabSpec(s); nts.setIndicator(s.replace('_', ' ')); nts.setContent(new TabHost.TabContentFactory(){ public View createTabContent(String tag) { ListView foodCabinetLV = new ListView(FoodCabinet.this); Cursor mCursor = dbHelper.getAllFoodsWithType(s); // Create an array to specify the fields we want to display in the list (only TITLE) String[] from = new String[]{FoodStorageDBHelper.KEY_NAME, FoodStorageDBHelper.KEY_YEAR,FoodStorageDBHelper.KEY_RANK}; // and an array of the fields we want to bind those fields to (in this case just text1) int[] to = new int[]{R.id.childname,R.id.childyear,R.id.childrank}; // Now create a simple cursor adapter and set it to display SimpleCursorAdapter notes = new SimpleCursorAdapter(FoodCabinet.this, R.layout.food_row, mCursor, from, to); foodCabinetLV.setAdapter(notes); startManagingCursor(mCursor); foodCabinetLV.setOnItemClickListener( new AdapterView.OnItemClickListener() { public void onItemClick(AdapterView arg0, View arg1, int arg2, long arg3) { Intent i = new Intent(); i.setClass(arg0.getContext(), EditFoodDialog.class); i.putExtra(FoodStorageDBHelper.KEY_ROWID, Long.toString(arg3)); startActivityForResult(i, LoadFoodOrganizer.ACTIVITY_EDIT); } }); return foodCabinetLV; } }); } For some reason, it doesn't show anything... it's a blank screen. Any help would be very much appreciated. Let me know! Thanks! Jon

  • How to configure Jetty to reload a WebAppContext when classes are changed

    - by Guss
    I'm developing a web application and I run Jetty as the development and testing environment when I develop under Eclipse. When I make changes to Java classes, Eclipse automatically compiles them to the build directory, but Jetty won't see the changes until I stop and start the server. I know that Jetty supports "hot deployment" using ContextDeployer that will refresh updated application contexts, but it relies on a context file in a context directory being updated - which is not very useful in my case. Is there a way to set up Jetty so that it will reload the web app when any of the classes it uses is updated? My current jetty.xml looks something like this: <?xml version="1.0"?> <!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure.dtd"> <Configure id="Server" class="org.eclipse.jetty.server.Server"> <Set name="ThreadPool"><!-- bla bla --></Set> <Call name="addConnector"><!-- bla bla --></Call> <Set name="handler"> <New id="Handlers" class="org.eclipse.jetty.server.handler.HandlerCollection"> <Set name="handlers"> <Array type="org.eclipse.jetty.server.Handler"> <Item> <New id="webapp" class="org.eclipse.jetty.webapp.WebAppContext"> <Set name="displayName">My Web App</Set> <Set name="resourceBase">src/main/webapp</Set> <Set name="descriptor">src/main/webapp/WEB-INF/web.xml</Set> <Set name="contextPath">/mywebapp</Set> </New> </Item> <Item> <New id="DefaultHandler" class="org.eclipse.jetty.server.handler.DefaultHandler"/> </Item> </Array> </Set> </New> </Set> </Configure>
