Description

Helper class to create (named and comparable) tagged types.

Classes
struct	Dumux::Utility::Tag< T >
	Helper class to create (named and comparable) tagged types Tags any given type. The tagged type is equality comparable and can be written to streams. A custom name can be provided by implementing the name() member function. More...

Namespaces
namespace	Dumux
	Adaption of the non-isothermal two-phase two-component flow model to problems with CO2.
namespace	Dumux::Utility
namespace	Dumux::Utility::Detail

Functions
template<class T1 , class T2 >
constexpr bool	Dumux::Utility::operator== (Tag< T1 >, Tag< T2 >)
	Tags are equality comparable and return true if the tagged types are equal. More...
template<class T1 , class T2 >
constexpr bool	Dumux::Utility::operator!= (Tag< T1 >, Tag< T2 >)
template<class T , std::enable_if_t< std::is_base_of_v< Tag< T >, T >, int > = 0>
auto	Dumux::Utility::operator<< (std::ostream &os, const T &t) -> std::enable_if_t< decltype(Detail::hasName(t))::value, std::ostream & >
	Return the class name of the tagged type calling t.name() More...

Variables
constexpr auto	Dumux::Utility::Detail::hasName = isValid([](auto&& t) -> decltype(t.name(), void()) {})
