| Detailed description | ||
| In software engineering, a design pattern is a general solution to a common problem in software design. One of these design patterns is called the Singleton. It's purpose can be described quite briefly as follows: Ensure a class has only one instance and provide a global point of access to it. It achieves this by only creating a new instance the first time it is referenced, and thereafter it simply returns the handle to the existing instance. -------------------------------------------------------------------------------------------- sTonClass is a base class that implements the singleton design pattern. The class can only be instantiated using a static function that assures that there is only one object of that class. If the class was already instantiated, it returns a reference to the previously created class object. The class also provides functions for store, retrieving and deleting object properties. |
