Detailed Description

Part of RTTI.

The type_info class describes type information generated by an implementation.

Definition at line 91 of file typeinfo.

Constructor & Destructor Documentation

◆ ~type_info()

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.

◆ type_info()

std::type_info::type_info ( const char *  __n)
inlineexplicitprotected

Definition at line 151 of file typeinfo.

Member Function Documentation

◆ before()

bool std::type_info::before ( const type_info __arg) const
noexcept

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

◆ hash_code()

size_t std::type_info::hash_code ( ) const
inlinenoexcept

Definition at line 118 of file typeinfo.

◆ name()

const char * std::type_info::name ( ) const
inlinenoexcept

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

Definition at line 102 of file typeinfo.
