Detailed Description

Part of RTTI.

The type_info class describes type information generated by an implementation.

Definition at line 88 of file typeinfo.

Constructor & Destructor Documentation

virtual std::type_info::~type_info () [virtual]

Destructor first. Being the first non-inline virtual function, this controls in which translation unit the vtable is emitted. The compiler makes use of that information to know where to emit the runtime-mandated type_info structures in the new-abi.

Member Function Documentation

const char* std::type_info::name () const [inline], [noexcept]

Returns an implementation-defined byte string; this is not portable between compilers!
