Member Enumeration Documentation

◆ Kind

enum clang::VTableComponent::Kind
Enumerator
CK_VCallOffset 
CK_VBaseOffset 
CK_OffsetToTop 
CK_RTTI 
CK_FunctionPointer 
CK_CompleteDtorPointer 

A pointer to the complete destructor.

CK_DeletingDtorPointer 

A pointer to the deleting destructor.

CK_UnusedFunctionPointer 

An entry that is never used.

In some cases, a vtable function pointer will end up never being called. Such vtable function pointers are represented as a CK_UnusedFunctionPointer.
