Design Patterns - Generic Singleton Pattern

Tue, 15 Jul 2008 22:21:20 GMT

A little follow up from yesterday 's Singleton Pattern, where I asked for some help on how you would approach a generic singleton. With the help of Andrew Stevenson and ExNihilo, we came up with the following Generic Singleton Pattern.

SingleTon Pattern in C#.net

Tue, 15 Jul 2008 04:14:54 GMT

The Singleton pattern ensures that a class only has one instance and provides a global point of access to it from a well-known access point. The class implemented using this pattern is responsible for keeping track of its sole instance rather than relying on global variables to single instances of objects.

Design Patterns - Singleton Pattern

Today we'll have a look at a well known pattern, the Singleton Pattern. Most people have already heard about this one. The definition: "Ensure a class has only one instance and provide a global point of access to it."

Static Singletons for ASP.NET Controls

Fri, 11 Jul 2008 14:23:09 GMT

When building generic ASP.NET Server controls that also provide a sort of API service to other custom controls or page level code, it's often necessary to ensure that only a single instance of a control exists, and that only that single instance of this control or component can be accessed in the context of an ASP.NET request. Using HttpContext and it's Item collection makes it easy to create reusable, cacheable instances and ensure you're only running a Singleton instance of it.

C# - Singleton Pattern vs. Static Classes

Fri, 04 Jul 2008 01:11:21 GMT

Problem: Store some common data in a singleton or static class about your program in an object array, which you store in a class. It saves state between usages and stores some caches, and must be initialized only once and shared in many code locations. Making a new object each time would be expensive.

Most people who don't know me personally assume that I value .NET Remoting above all other means of developing distributed applications. They might also assume that I'll use Remoting as a catch-all solution to any distributed application.

Singleton - the most overused pattern

Fri, 09 Mar 2007 10:01:01 GMT

The innocent little singleton in your middle tier is not so innocent after all. This article discusses the design issues inherent in unwisely using the Singleton Design Pattern. In particular it discusses the kind of concurrency and scalability issues that arise from use of singleton in high-use, concurrent applications. It also suggests alternative designs that should be used for business logic classes.

PrestonLee.com - Singletons Cause Cancer

Sat, 15 Jul 2006 03:04:35 GMT

Singletons can be hazardous to your health, seriously jeopardize your family's safety, and have been classified as "terrorist patterns" by the U.S. government. The fact that an application only needs one instance of something does not mean the object should be designed that way, and there aren't very many scenarios where singletons are appropriate. Do as the Jedi do and use them with consideration and responsibly.
