NAME¶

std::type_index::operator==,!=,,>=, - std::type_index::operator==,!=,,>=,

Synopsis¶

bool operator==( const type_index& rhs ) const noexcept; (1) (since C++11)
bool operator!=( const type_index& rhs ) const noexcept; (2) (since C++11)
(until C++20)
bool operator<( const type_index& rhs ) const noexcept; (3) (since C++11)
bool operator<=( const type_index& rhs ) const noexcept; (4) (since C++11)
bool operator>( const type_index& rhs ) const noexcept; (5) (since C++11)
bool operator>=( const type_index& rhs ) const noexcept; (6) (since C++11)
std::strong_ordering operator<=>( const type_index& rhs ) const (7) (since C++20)
noexcept;

Compares the underlying std::type_info objects.

1-2) Checks whether the underlying std::type_info objects refer to the same type.
3-7) Compares the underlying std::type_info objects as defined by an
implementation-defined ordering. The comparison is done by type_info::before.

The != operator is synthesized from operator==. (since C++20)

Parameters¶

rhs - another type_index object to compare to

Return value¶

1) true if the underlying std::type_info objects refer to the same type, false
otherwise
2) true if the underlying std::type_info objects refer not to the same type, false
otherwise
3-6) true if the types referred by the underlying std::type_info objects are ordered
by corresponding order, false otherwise.
7) std::strong_ordering::equal if the underlying std::type_info objects refer to the
same type, otherwise std::strong_ordering::less if *this's underlying std::type_info
object precedes rhs's in the implementation-defined ordering, otherwise
std::strong_ordering::greater.
