NAME

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

Synopsis

bool operator==( const type_index& rhs ) const noexcept; (since C++11)
bool operator!=( const type_index& rhs ) const noexcept; (since C++11)
bool operator<( const type_index& rhs ) const noexcept; (since C++11)
bool operator<=( const type_index& rhs ) const noexcept; (since C++11)
bool operator>( const type_index& rhs ) const noexcept; (since C++11)
bool operator>=( const type_index& rhs ) const noexcept; (since C++11)

Compares the underlying std::type_info objects.
1-2) Checks whether the underlying std::type_info objects refer to the same type.
3-6) Compares the underlying std::type_info objects as defined by an implementation-defined ordering. The comparison is done by type_info::before.

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.
