Singletons in 4D

4D 20 R5 delivers a powerful feature for developers: Singletons!

The singleton design pattern creates a single instance of a class accessible throughout your application.

This pattern offers many benefits, including:

  • host for interprocess values,
  • utility classes,
  • a base for the factory design pattern,
  • and many more.
