LotusScript Classes - Singleton Addendum

After my blog post last week on LotusScript classes and using Static Property Get to create singletons, there was some discussion on OpenNTF's Discord about the challenges of forcing use of the singleton. "Singleton" is a misnomer really, because it's not scoped to the JVM asaJava singleton would be. But I can't think of a better name yet, so I'll stick with that terminology, but be aware of the specific scope for static instances in LotusScript / VoltScript.

LotusScript Classes Deep Dive Part Four

Before going onto that one more LotusScript function that is relevant to classes, there is another topic worth discussing with regard to classes. This is not functionality in LotusScript classes itself, but a design pattern which has been available ever since LotusScript began, but one which has become very commonly used in other languages as they have developed. It fits well after the discussion on using Static for creating builder classes, because the builder pattern in Java is where it's most widely used. The design pattern I'm referring to is a fluent interface.

LotusScript Classes Deep Dive Part Two

In the last part I covered the basics of what constitutes a Class in LotusScript / VoltScript. I also said that user-defined classes in LotusScript are often avoided because developers can interact with their data via the platform classes in lsxbe (Notes...) and lsxui (NotesUI...). When classes are used in proprietary applications they may typically be very straightforward - standalone classes with no inheritance. But there is much more possible, as Java developers will be aware of.
