override (C++ Component Extensions)

 

For the latest documentation on Visual Studio 2017 RC, see Visual Studio 2017 RC Documentation.

The override context-sensitive keyword indicates that a member of a type overrides a base class or a base interface member.

The override keyword is valid when compiling for native targets (default compiler option), Windows Runtime targets (/ZW compiler option), or common language runtime targets (/clr compiler option).

For more information about override specifiers, see override Specifier and Override Specifiers and Native Compilations.

For more information about context-sensitive keywords, see Context-Sensitive Keywords.

Example

The following code example shows that override can also be used in native compilations.

// override_keyword_1.cpp  
// compile with: /c  
struct I1 {  
   virtual void f();  
};  
  
struct X : public I1 {  
   virtual void f() override {}  
};  

Example

The following code example shows that override can be used in Windows Runtime compilations.

// override_keyword_2.cpp  
// compile with: /ZW /c  
ref struct I1 {  
   virtual void f();  
};  
  
ref struct X : public I1 {  
   virtual void f() override {}  
};  

Requirements

Compiler option: /ZW

Example

The following code example shows that override can be used in common language runtime compilations.

// override_keyword_3.cpp  
// compile with: /clr /c  
ref struct I1 {  
   virtual void f();  
};  
  
ref struct X : public I1 {  
   virtual void f() override {}  
};  

Requirements

Compiler option: /clr
