override (C++ Component Extensions)
The latest version of this topic can be found at 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.
Remarks
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.
Examples
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
