Singleton

Hi Smart,

 A singleton is a single-instance object. It is highly efficient and very graceful. Singletons have a static property that you must access to get the object reference.

Singletons preserve the conventional class approach, and don't require that you use the static keyword everywhere. They may be more demanding to implement at first, but will greatly simplify the architecture of your program. Unlike static classes, we can use singletons as parameters or objects.

Example of my C# singleton class:

using System;

namespace Example
{
  public class SingletonUtility
  {
    private static SingletonUtility _instance;

    private SingletonUtility()
    {
      // Caching logic here.
    }

    public static SingletonUtility GetInstance()
    {
      if (_instance == null)
        _instance = new SingletonUtility();

      return _instance;
    }
  }
}
