class

问题 If I wanted to use the same factory for any class that extended my base class, would I want to turn the base class factory into a named function, or is there a better way to do this? $serviceManager => array( 'factories' => array( 'someBaseClass' => function($thisServiceManager) { $db = $thisServiceManager->get('db'); $thisBaseClass = new \myNamespace\thisBaseClass($db); return $thisBaseClass; }, ), ); EDIT Further to the answer I accepted, here's the code I've tested that works. Class File

问题 Hi i have two view controller: FirstViewController and SecondViewController FirstViewController.h #import <UIKit/UIKit.h> @interface FirstViewController: { NSString *prStr; } -(IBAction)setString; @property (nonatomic, retain) NSString *prStr; @end FirstViewController.m #import"FirstViewController.h" @implementation FirstViewController @synthesize prStr; -(IBAction)setString{ prStr = [[NSString alloc]initWithFormat:@"1"]; } SecondViewController.h #import <UIKit/UIKit.h> @class

问题 I am using three files on a project: index.php , class.php , and styles.css . All my functions reside within a php class in the class.php file: <?php class Club { //Private Data private $HostName; //typically "localhost" private $UserId; private $Password; private $DBName; private $Con; //MySQL Connection //Public Methods //Constructor public function __construct($host = NULL, $uid = NULL, $pw = NULL, $db = NULL) { $this->HostName = $host; $this->UserID = $uid; $this->Password = $pw; $this-

问题 So I recently learnt that by importing a class into my main class I can access its functions from any other class. BUT.... one of my functions in the imported class needs to add display objects to the stage. I accessed the static function just fine but it can't add objects to the stage. It doesn't even seem to recognise addChild. Is this because it is not in the display list itself? What am I missing here? How would you guys solve this issue. I was so close, yet so far! Code is like this:

问题 In VB.NET 2010, How would one go about creating a list of Parent classes where each Parent has it's own list of Child classes. Where the list of child classes could be as few as 1 child or as many as a few hundred child objects? 回答1: Dim ChildList as generic.list(of object) Dim ParentList as generic.list(of ChildList) You can do it like above 回答2: Sounds like you need a LinkedList object: LinkedList Outer; where ParentType is a class that has another LinkedList object of it own: Public Class

问题 I have classical complaint - rebuilding and reloading the web app takes too long. I want to compile the classes (preferrably from the IDE) or change a static file and let the server check what changed and act approprietly (reload the class/file). What are my options for Wicket + JDK 1.6 ? I'd prefer Jetty, but Tomcat, JBoss AS or others are good, too. I am not using the ReloadingWicketFilter since I use mvn jetty:run-exploded because it's the simplest way to run my app with desired

问题 Lets imagine: // assembly 01 abstract class Foo { abstract void Bar(); } class AdvancedFoo : Foo { override void Bar() { base.Foo(); ... } } sealed class SuperiorFoo : AdvancedFoo { override sealed void Bar() { base.Foo(); } } And then I want to reference that assembly 01 from my 02 asm and replace the intermediate base class (and only it) so the instances of a SuperiorFoo were acting like they are inhereting from assembly 02 's AdvancedFoo . // assembly 02 class AdvancedFoo : Foo { override

问题 So following is the set up of different classes that I need to create: Author – AuthorId, AuthorName, DateOfBirth, State, City, Phone. Publisher – PublisherId, PublisherName, DateOfBirth, State, City, Phone. Category – CategoryId, CategoryName, Description. Book – BookId, Category, Title, Author, Publisher, Description, Price, ISBN, PublicationDate. Now as you can see Author in Book and AuthorId in Author classes are the same.How to achieve this in C# 回答1: First of all, you need to

问题 Is there any way to let multiple class share the same instance of another class? So in my c# program i've got three class Gamelogic(A), FPSController(B), and SpawnPlayer(C). In my case class B and C would use and alter some variables in A, in order to use the variables i'm currently instantiating A in two different classes and then use dot notation to access the variable from the instance of A, but the problem is that after A instantiated in different classes, the change in instance.variable

问题 I'm making a program that asks the user to login, and I'm wondering how I can make it so it checks if an instance of my Username class exists. Oh and please excuse my sloppy and disorganized coding, I'm not very good at it. quit_login = 1 class Usernames: def __init__(self, password): self.password = password testlogin = Usernames("foo") def login_e(): a = raw_input("Please enter a username: ") new_pass = "" if isinstance(a, Usernames): a = Usernames(new_pass) print Usernames else: login_pass
