Somehow I got lost in an article that led me here: http://www.javascriptkata.com/2007/0...e-a-singleton/
Having recently seen someone else mentioning a Singleton pattern in JavaScript, I wonder,
like the commenter Aaron, why anyone would use one?
For anyone who doesn't know what a Singleton pattern is, look here: http://en.wikipedia.org/wiki/Singleton_pattern
"the singleton pattern is a design pattern that is used to restrict instantiation of a
class to one object"
Which basically means we end up with an object that has the ability to restrict itself to
only one instance at a time.
Anyway, I would appreciate any *clear* examples of how one might *require* a Singleton
pattern.

JavaScript can support much simpler formulations. For example:
var catNames = function () {
var names = [];
return {
add: function (catName) {
names.push(catN ame);
},
removeLast: function () {
return names.pop();
},
alertAllCats: function () {
alert(names.joi n(","));
}
};
}(); http://javascript.crockford.com/ This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

Hello everyone, I have been researching the Singleton Pattern. Since the
singleton pattern uses a private constructor which in turn reduces
extendability, if you make the Singleton Polymorphic what sort of

Also, I see that a singleton needs to be set up with certain data such as
file name, database URL etc. What issues are involved in this, and how
would you do this?

foo() generates elements with event handlers that invoke foo function
properties.
Is this an abhorrent or misthought pattern ?
It allows just the one occurence of identifier /foo/ to be changed to
/whatever/ when need arises and everything should still work.
function foo () {
var callee = arguments.callee

Let's say I'm writing a business app and I want there to be only one
instance of the Customer object for each particular customer (representing a
database record) being edited.
Would it be possible to extend the Singleton pattern to handle this?
Assuming that my Customer class follows the Singleton pattern (particularly
Skeet's 4th version) I'm thinking if I add
private static SomeCollectionType customers;

I wish to build a framework for our developers that will include a singleton
pattern.
But it can not be a base class because it has a private constructor and
therefore can be inherit.
I thought maybe a Template can be use for that, but C# does not support
Templates (will be C# generics in mid 2005).
Does anyone have a solution on how the singleton pattern can be written, in
C#, as a framework/ infrastructure class, so users can use this...

At the beginning of my C# days (about 6 months ago) I learned about the
Singleton pattern and implemented for Reference data, such as the kind that
appears in an Options dialog box. My Singleton code looks like this:
public sealed class Reference
{
private static readonly Reference instance = new Reference();
// Make the default constructor private, so that nothing can directly
create it.

I have been playing around with a couple of ways to add inheritance to a
JavaScript singleton pattern. As far as I'm aware, using an anonymous
constructor to create a singleton does not allow any kind of inheritance:
singletonObj = new function() {
this.prop = true;
}
Here are two ways to create a singleton with inheritance:

Design Pattern: The Singleton
Overview
Use the Singleton Design Pattern when you want to have only one instance of a class. This single instance must have a single global point of access. That is, regardless of where the object is hidden, everyone needs access to it.
The global point of access is the object's Instance() method.
Individual users need to be prevented from creating their own instances of the Singleton.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
