An object's virtual method table will contain the addresses of the object's dynamically bound methods. Method calls are performed by fetching the method's address from the object's virtual method table. The virtual method table is the same for all objects belonging to the same class, and is therefore typically shared between them.
Overrides vs override - for marking a virtual method as overridden; Shared vs static - for declaring methods that do not require an explicit instance of an object; Some C# keywords such as sealed represent different things when applied to methods as opposed to when they are applied to class definitions. VB.NET, on the other hand, uses different ...
In C#, class methods, indexers, properties and events can all be overridden. Non-virtual or static methods cannot be overridden. The overridden base method must be virtual, abstract, or override. In addition to the modifiers that are used for method overriding, C# allows the hiding of an inherited property or method.
A pure virtual function or pure virtual method is a virtual function that is required to be implemented by a derived class if the derived class is not abstract. Classes containing pure virtual methods are termed "abstract" and they cannot be instantiated directly.
Hook methods are of particular importance in the template method pattern where common code in an abstract class can be augmented by custom code in a subclass. In this case each hook method is defined in the abstract class with an empty implementation which then allows a different implementation to be supplied in each concrete subclass.
extern - Specifies that a method signature without a body uses a DLL-import. override - Specifies that a method or property declaration is an override of a virtual member or an implementation of a member of an abstract class. readonly - Declares a field that can only be assigned values as part of the declaration or in a constructor in the same ...
The non-virtual interface pattern (NVI) controls how methods in a base class are overridden. Such methods may be called by clients and overridable methods with core functionality. [1] It is a pattern that is strongly related to the template method pattern. The NVI pattern recognizes the benefits of a non-abstract method invoking the subordinate ...
Code morphing is an approach used in obfuscating software to protect software applications from reverse engineering, analysis, modifications, and cracking.This technology protects intermediate level code such as compiled from Java and .NET languages (Oxygene, C#, Visual Basic, etc.) rather than binary object code.
