As I understand, you want your abstract class to only be implemented by other classes in the same assembly (e.g. it is internal) but the derived classes could be public. The way to do this is to make the abstract base class public, but give it an internal default constructor: public abstract class MyClass { … Read more
UPDATE Since 2019.2 version you can enable it in the Project view options, toggle the Show Visibility Icons: For older versions: This option was disabled intentionally, see this comment for the explanation: This information was intentionally removed, as we believe that it brings more clutter than actual value. To enable it back add -Dide.projectView.show.visibility=true in … Read more
This just means that the getter for numberOfEdits is public, but the setter is private. There’s nothing more to it. The reason in this case is so that you can read numberOfEdits publicly, but you can only set it via changing value. If it were fully public, then anyone could set it, but if it … Read more
No, Constructors can be public, private, protected or default(no access modifier at all). Making something private doesn’t mean nobody can access it. It just means that nobody outside the class can access it. So private constructor is useful too. One of the use of private constructor is to serve singleton classes. A singleton class is … Read more
Simply because being public makes no sense in an abstract class. An abstract class by definition cannot be instantiated directly. It can only be instantiated by an instance of a derived type. Therefore the only types that should have access to a constructor are its derived types and hence protected makes much more sense than … Read more
In theory it does not matter if you say public static final or final static public, but if you follow the usual convention, other people will able to read your code more easily. Here is the preferred order: [ public | protected | private ] static abstract synchronized [ transient | volatile ] final native … Read more
fileprivate is one of the new Swift 3 access modifiers that replaces private in its meaning. fileprivate defines an entity (class, extension, property, …) as private to everybody outside the source file it is declared in, but accessible to all entities in that source file. private restricts the entity in the direct enclosing scope.
Private is a modifier than gives the scope of the class, sub, or function. A sub and a function are both subroutines, or sections of code that can be called in the program. The difference between them is that a function has a return value and a sub does not. A class is a group … Read more
A final class cannot be extended, period. A sealed trait can only be extended in the same source file as it’s declared. This is useful for creating ADTs (algebraic data types). An ADT is defined by the sum of its derived types. E.g.: An Option[A] is defined by Some[A] + None. A List[A] is defined … Read more
Dim and Private work the same, though the common convention is to use Private at the module level, and Dim at the Sub/Function level. Public and Global are nearly identical in their function, however Global can only be used in standard modules, whereas Public can be used in all contexts (modules, classes, controls, forms etc.) … Read more
