What’s going on here? You’ve misunderstood the meaning of protected. You can access the protected members declared in A from within C, but only for instances of C or subclasses of C. See section 6.6.2 of the JLS for details of protected access. In particular: Let C be the class in which a protected member … Read more
Simply NO. Nothing unless its in a nested Class Classes and structs that are not nested within other classes or structs can be either public or internal. A type declared as public is accessible by any other type. A type declared as internal is only accessible by types within the same assembly. Classes and structs … Read more
In C++ there is no notion of an entire class having an access specifier the way that there is in Java or C#. If a piece of code has visibility of a class, it can reference the name of that class and manipulate it. That said, there are a few restrictions on this. Just because … Read more
The reason this doesn’t work is because C# doesn’t allow cross-hierarchy calling of protected methods. Say there was a class E that also derived from C: C / \ D E Then the reference you’re trying to call the method on could actually be an instance of type E and thus the method could resolve … Read more
The double-edged sword of serialization Unity wants to make things easier for everyone, including people with limited coding knowledge (beginners, designers). To help them out, Unity displays data in the inspector. This allows the coder to code and the designer to design by tweaking the values without opening MonoDevelop/an IDE. There are two ways to … Read more
“access modifier” is the official term for private, protected and public used in the Java language specification. “access specifier” is used synonymously in the Java API doc, but this is the first time I’ve noticed that. It’s probably better to stick with the JLS term.
You can create package-private classes by omitting the security modifier (public, private) from the class’s declaration. package com.sample; class MyPackagePrivateClass { … }
In this case, list is the name of the package, which you are importing via import “container/list”, and its public members are upper case, like List. The rule is that public functions, types, etc., should be upper case. You can alias imported packages however you want, but by default it is just the name of … Read more
Elements defined in a namespace may be explicitly declared public or internal. They may not be explicitly declared private or protected (or protected internal) because these modifiers only make sense for members of a class. Your protected class GetDataBL, for example, makes no sense, because “protected” means “accessible to classes that inherit from the containing … Read more
Changing the access modifier of a method in a derived type is pointless that’s why it’s not allowed: Case 1: Override with a more restrictive access This case is obviously not allowed due to the following situation: class Base { public virtual void A() {} } class Derived: Base { protected override void A() } … Read more
