  • 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?

  • Injecting the mailer service, got "The service definition 'mailer' does not exist"?

    - by Gremo
    This is the class where the service mailer should be injected: namespace Gremo\SkebbyBundle\Transport; use Swift_Mailer; use Gremo\SkebbyBundle\Message\AbstractSkebbyMessage; class MailerTransport extends AbstractSkebbyTransport { /** * @var \Swift_Mailer */ private $mailer; public function __construct(Swift_Mailer $mailer) { $this->mailer = $mailer; } /** * @param \Gremo\SkebbyBundle\Message\AbstractSkebbyMessage $message * @return void */ public function executeTransport(AbstractSkebbyMessage $message) { /* ... */ } } Service id is gremo_skebby.transport.mailer, placed inside mailer.xml file: <parameters> <parameter key="gremo_skebby.converter.swift_message.class"> Gremo\SkebbyBundle\Converter\SwiftMessageConverter </parameter> <parameter key="gremo_skebby.transport.mailer.class"> Gremo\SkebbyBundle\Transport\MailerTransport </parameter> </parameters> <services> <service id="gremo_skebby.converter.swift_message" class="%gremo_skebby.converter.swift_message.class%" public="false" /> <service id="gremo_skebby.transport.mailer" class="%gremo_skebby.transport.mailer.class%" public="false" parent="gremo_skebby.tranport.abstract_transport"> <argument type="service" id="mailer" /> </service> </services> When i try to inject the gremo_skebby.transport.mailer into another service (an helper) i get: Symfony\Component\DependencyInjection\Exception\InvalidArgumentException : The service definition "mailer" does not exist. That is strange, because command php app/console container:debug shows that the mailer service actually exists: mailer container Swift_Mailer I'm loading mailer.xml file dynamically by the extension: if(in_array($configs['transport'], array('http', 'rest', 'mailer'))) { $loader->load('transport.xml'); $loader->load($configs['transport'] . '.xml'); $container->setAlias('gremo_skebby.transport', 'gremo_skebby.transport.' . $configs['transport']); } $loader->load('skebby.xml'); ... and gremo_skebby.transport service is injected into gremo_skebby.skebby service (skebby.xml): <parameters> <parameter key="gremo_skebby.skebby.class"> Gremo\SkebbyBundle\Skebby </parameter> </parameters> <services> <service id="gremo_skebby.skebby" class="%gremo_skebby.skebby.class%"> <argument type="service" id="gremo_skebby.transport" /> </service> </services> A quick test is giving me the same InvalidArgumentException: public function testSkebbyWithMailerTransport() { $loader = new GremoSkebbyExtension(); $container = new ContainerBuilder(); $config = $this->getEmptyConfiguration(); $loader->load(array($config), $container); $this->assertTrue($container->hasDefinition('gremo_skebby.transport.mailer')); $this->assertTrue($container->hasDefinition('gremo_skebby.skebby')); $this->assertInstanceOf('Gremo\SkebbyBundle\Skebby', $container->get('gremo_skebby.skebby')); }

    A periodic computer generated message (simplified): Hello user123, - (604)7080900 - 152 - minutes Regards Using python, how can I extract "(604)7080900", "152", "minutes" (i.e. any text following a leading "- " pattern) between the two empty lines (empty line is the \n\n after "Hello user123" and the \n\n before "Regards").

  • User sessions with jquery and Ajax

    - by John
    I am using jquery to set a session, i have a php page which gets the values of the person logging. The value in the session array, is then used in another page where, it is stored in a hidden field for database entry.The problem is, the value is not set unless you refresh the page of which beats the purpose of AJAX and Jquery.Again,the session seems to be one session behind.How can I do this without page refresh/ reload?

  • C# function normal return value VS out or ref argument

    - by misha-r
    Hi People, I've got a method in c# that needs to return a very large array (or any other large data structure for that matter). Is there a performance gain in using a ref or out parameter instead of the standard return value? I.e. is there any performance or other gain in using void function(sometype input, ref largearray) over largearray function(sometype input) ? Thanks in advance!

  • Parallel For Loop - Problems when adding to a List - Possible .Net Bugs

    - by Kevin Crowell
    I am having some issues involving Parallel for loops and adding to a List. The problem is, the same code may generate different output at different times. I have set up some test code below. In this code, I create a List of 10,000 int values. 1/10th of the values will be 0, 1/10th of the values will be 1, all the way up to 1/10th of the values being 9. After setting up this List, I setup a Parallel for loop that iterates through the list. If the current number is 0, I add a value to a new List. After the Parallel for loop completes, I output the size of the list. The size should always be 1,000. Most of the time, the correct answer is given. However, I have seen 3 possible incorrect outcomes occur: The size of the list is less than 1,000 An IndexOutOfRangeException occurs @ doubleList.Add(0.0); An ArgumentException occurs @ doubleList.Add(0.0); The message for the ArgumentException given was: Destination array was not long enough. Check destIndex and length, and the array's lower bounds. What could be causing the errors? Is this a .Net bug? Is there something I can do to prevent this from happening? Please try the code for yourself. If you do not get an error, try it a few times. Please also note that you probably will not see any errors using a single-core machine. using System; using System.Collections.Generic; using System.Threading.Tasks; namespace ParallelTest { class Program { static void Main(string[] args) { List<int> intList = new List<int>(); List<double> doubleList = new List<double>(); for (int i = 0; i < 250; i++) { intList.Clear(); doubleList.Clear(); for (int j = 0; j < 10000; j++) { intList.Add(j % 10); } Parallel.For(0, intList.Count, j => { if (intList[j] == 0) { doubleList.Add(0.0); } }); if (doubleList.Count != 1000) { Console.WriteLine("On iteration " + i + ": List size = " + doubleList.Count); } } Console.WriteLine("\nPress any key to exit."); Console.ReadKey(); } } }

  • Sorting based on existing elements in xslt

    - by Teelo
    Hi , I want to sort in xslt based on existing set of pattern . Let me explain with the code: <Types> <Type> <Names> <Name>Ryan</Name> </Names> <Address>2344</Address> </Type> <Type> <Names> </Name>Timber</Name> </Names> <Address>1234</Address> </Type> <Type> <Names> </Name>Bryan</Name> </Names> <Address>34</Address> </Type> </Types> Right now I m just calling it and getting it like (all hyperlinks) Ryan Timber Bryan Now I don't want sorting on name but I have existing pattern how I want it to get displayed.Like Timber Bryan Ryan (Also I don't want to lose the url attached to my names earlier while doing this) I was thinking of putting earlier value in some array and sort based on the other array where I will store my existing pattern. But I am not sure how to achieve that.. My xslt looks like this now(there can be duplicate names also) <xsl:for-each select="/Types/Type/Names/Name/text()[generate-id()=generate-id(key('Name',.)[1])]"> <xsl:call-template name="typename"> </xsl:call-template> </xsl:for-each> <xsl:template name="typename"> <li> <a href="somelogicforurl"> <xsl:value-of select="."/> </a> </li> </xsl:template> I am using xsl 1.0

  • Python: Script works, but seems to deadlock after some time

    - by sberry2A
    I have the following script, which is working for the most part Link to PasteBin The script's job is to start a number of threads which in turn each start a subprocess with Popen. The output from each subprocess is as follows: 1 2 3 . . . n Done Bascially the subprocess is transferring 10M records from tables in one database to different tables in another db with a lot of data massaging/manipulation in between because of the different schemas. If the subprocess fails at any time in it's execution (bad records, duplicate primary keys, etc), or it completes successfully, it will output "Done\n". If there are no more records to select against for transfer then it will output "NO DATA\n" My intent was to create my script "tableTransfer.py" which would spawn a number of these processes, read their output, and in turn output information such as number of updates completed, time remaining, time elapsed, and number of transfers per second. I started running the process last night and checked in this morning to see it had deadlocked. There were not subprocceses running, there are still records to be updated, and the script had not exited. It was simply sitting there, no longer outputting the current information because no subprocces were running to update the total number complete which is what controls updates to the output. This is running on OS X. I am looking for three things: I would like to get rid of the possibility of this deadlock occurring so I don't need to check in on it as frequently. Is there some issue with locking? Am I doing this in a bad way (gThreading variable to control looping of spawning additional thread... etc.) I would appreciate some suggestions for improving my overall methodology. How should I handle ctrl-c exit? Right now I need to kill the process, but assume I should be able to use the signal module or other to catch the signal and kill the threads, is that right? I am not sure whether I should be pasting my entire script here, since I usually just paste snippets. Let me know if I should paste it here as well.

  • How to check if a integer is sum of given integers?

    - by p3trix
    Lets say I have a integer result and an array of integers, lets say [a,b,c] (not a fixed length). I need to detect if result=a*i +b*j + c*k, with i,j,k=0. I prefer a solution in C/C# if it is possible. PS The problem is from a reservation system, a trip can be sold if its durations is a combination of given durations. Thanks!

  • WPF: Binding with title and subitems

    - by John
    I am having some issues trying to learn WPF. What I am trying to do is to bind a class that has a string and an array of strings. I would like to bind the string as the title and array as the contents of an expander, but I am having difficulties. What am I missing to make this work? Any help would be appreciated, TIA. This is the code I have thus far: XAML <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <Grid> <ListBox Grid.Column="0" Name="lbTopics" ItemsSource="{Binding}"> <ListBox.ItemTemplate> <DataTemplate> <Expander Header="{Binding Path=TopicName}" > <Expander.Content> <ListBox> <ListBox.ItemTemplate> <DataTemplate> <Label Content="{Binding Path=(ItemName)}" Width="120px" Height="32px" Foreground="Black" /> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </Expander.Content> </Expander> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </Grid> C# namespace WpfApplication1 { public partial class Window1 : Window { public Window1() { InitializeComponent(); lbTopics.DataContext = new Topics(); } } public class Topics : ObservableCollection<Topic> { public Topics() { for (int i = 0; i < 10; i++) { this.Add(new Topic(i)); } } } public class Topic { public Topic(int i) { TopicName = "Topic " + i; ItemName = new List<string>(10); for (int j = 0; j < 10; j++) { ItemName.Add(i + " - Item " + j); } } public string TopicName { get; set; } public List<string> ItemName { get; set; } } }
