Detailed Description

Part of RTTI.

The type_info class describes type information generated by an implementation.

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.

std::type_info::type_info (const char * __n) [inline], [explicit], [protected]

Definition at line 152 of file typeinfo.

Member Function Documentation

bool std::type_info::before (const type_info & __arg) const [noexcept]

Returns true if *this precedes __arg in the implementation's collation order.

size_t std::type_info::hash_code () const [inline], [noexcept]

Definition at line 119 of file typeinfo.

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

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

Definition at line 103 of file typeinfo.
