override (C++ Component Extensions)

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 (C++ Component Extensions).

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
