Android Question Should Private subs be callable from outside a module?

[Computersmith64]

In languages other than B4A (eg: Swift, Obj-C, Java), a function / method declared as Private is not visible from outside the class it's declared in. For the function to be visible, it has to be declared as Public. In B4A the same applies to classes, but not modules it seems.

I always thought that to call a sub in one module from another using CallSub, the sub being called had to be declared as Public - however by accident I discovered today that I was calling a sub declared as Private from another sub using CallSub.

Is this intended behavior?

Private subs are indeed not visible from outside and they cannot be called directly. You can still call them with CallSub. This is similar to the reflection features available in Java and Objective C.

The visibility scope is a tool for the developer. It is not a security feature.
