Class Utility


«abstract» Utility
"Utility classes" contain only static methods and attributes. This means especially you can't create an instance of such classes.
As an example they are usefull to group full static functions of the same domain within a class namespace instead of having them clutter your global namespace.
To create a utility class, simply add "extends Utility" to your class definition. Note: this class is abstract by intention not by syntax.
