How do you call a factory? As defined below.
angular.module('fb.services', []).factory('getQueryString', function () {
return {
call: function () {
var result = {}, queryString = qs.substring(1),
re = /([^&=]+)=([^&]*)/g,
m;
while (m = re.exec(queryString))

Hi,
I am having a little design crisis, I am making a Plane class, which is made of
an engine
2 wings
and N seats
The engine takes in a engine size, and the wings have a span.
would this still be feasible to have a PlaneFactory, when the factory may have to take in multiple parameters to setup the plane (wings, engine, no of seats)

In Head-First Design Patterns, they use a pizza shop example to demonstrate the factory method pattern.
public abstract class PizzaStore {
public Pizza orderPizza(String type) {
Pizza pizza;
pizza = createPizza(type);
pizza.prepare();
pizza.bake();
pizza.cut();
pizza.box();
return pizza;
}

Hello Everyone
There are already quite some posts about the Singleton-Pattern around, but I would like to start another one on this topic since I would like to know if the Factory-Pattern would be the right approach to remove this "anti-pattern".
In the past I used the singleton quite a lot, also did my fellow collegues since it is so…
Hi,
Im making a factory method that returns new instances of my objects. I would like to prevent anyone using my code from using a public constructor on my objects. Is there any way of doing this?
How is this typically accomplished:
public abstract class CarFactory
{
public abstract ICar CreateSUV();
}
public class MercedesFactory…
I have a wrapper class for the Bitmap .NET class called BitmapZone.
Assuming we have a WIDTH x HEIGHT bitmap picture, this wrapper class should serve the purpose of allowing me to send to other methods/classes itself instead of the original bitmap. I can then better control what the user is or not allowed to do with the picture (and I…
Currently have a Factory class that features a GetSelector function, which returns a concrete implementation of ISelector. I have several different classes that implement ISelector and based on a setting I would like to receive the appropriate ISelector back.
public interface ISelector
{
string GetValue(string Params);
}

I have factory that looks something like the following snippet. Foo is a wrapper class for Bar and in most cases (but not all), there is a 1:1 mapping. As a rule, Bar cannot know anything about Foo, yet Foo takes an instance of Bar. Is there a better/cleaner approach to doing this?
public Foo Make( Bar obj )
{
if( obj is Bar1 )

Consider a usecase where you need to send the same file over to five different ftp servers. The first thought that might come to mind is to create five FtpAdapter references one for each connection-factory location. However, this is not the most optimal approach and this is exactly where "Dynamic Partner Links" come…
Why does following code raise an exception (in createObjects call to map::at)
alternativly the code (and its output) can be viewed here
intererestingly the code works as expected if the commented lines are uncommented with both microsoft and gcc compiler (see here), this even works with initMap as ordinary static variable instead…
I have a simple class library (COM+ service) written in C# to consume 5 web services: Add, Minus, Divide, Multiply and Compare.
I've created the abstract product and abstract factory classes. The abstract product named WS's code:

I have a generic abstract class Factory<T> with a method createBoxedInstance() which returns instances of T created by implementations of createInstance() wrapped in the generic container Box<T>.
abstract class Factory<T> {
abstract T createInstance();
public final Box<T> createBoxedInstance() {

I love the idea behind Solution Factory project. But, unfortunately this project have a few bugs.
Is anyone using it successfully with visual studio 2010?
Is there any other better option for the same task? (of creating a new project based on existed one).
I want to create a class, that is flexible so I can switch implementations.
Problem: Store files/documents
Options: either store locally on the server filesystem, database or etc.
Can someone help with a skeleton structure of the class, and how I would call it?
I am not using an IoC, and don't really want to just yet. I just…
Hi:
I want to know when we need to use the abstract factory pattern.
Here is an example,I want to know if it is necessary.
The UML
THe above is the abstract factory pattern, it is recommended by my classmate.
THe following is myown implemention. I do not think it is necessary to use the pattern.
And the following is some…
I see the word thrown around often, and I may have used it myself in code and libraries over time, but I never really got it. In most write-ups I came across, they just went on expecting you to figure it out.
What is a Class Factory? Can someone explain the concept?
Currently I have created a ABCFactory class that has a single method creating ABC objects. Now that I think of it, maybe instead of having a factory, I could just make a static method in my ABC Method. What are the pro's and con's on making this change? Will it not lead to the same? I don't foresee having other classes…
I found a lot of links on metaclasses, and most of them mention that they are useful for implementing factory methods. Can you show me an example of using metaclasses to implement the design pattern?
Let's say you have two classes that extend UserControl. Each of the controls provides a custom event (this could be done by using an interface).
You want to display one of the controls in the odd days and the other in the even days.
You also want to be able to drag&drop (Visual Studio) the UserControl on your…
I'm using the jQuery UI Widget Factory to build a jQuery plugin.
My plugin binds custom events to the window...
_subscribe: function() {
$(window).on("dragger.started", function() { ... });
}
I am wondering how to go about removing these events, when a particular instance of the plugin is destroyed. If I…
I have a factorymethod that either returns an object of baseclass or one that is of derivedclass (a derived class of baseclass). The derived class has a method virtual void foo(int x) that takes one argument. baseclass however has virtual void foo() without an argument.
In my code, a factory method returns a…
Hi,
I am using spring to initialise my beans. I have configured a bean which I intend to use as a factory bean.
<bean id="jsServicesFactory" class="x.y.z.JSServicesFactory" />
It is a very basic class - which has 4 getter methods. One example is
public final PortletRegistry getPortletRegistry()…
