operator()() [1/4]

template<class T , std::enable_if_t< std::conjunction_v< has_member_variable_state< T >, std::negation< has_member_state< T >>, std::negation< has_non_member_state< T >>>, int > = 0>

constexpr decltype(auto) beluga::state_detail::state_fn::operator() ( T &&  t ) const

inlineconstexprnoexcept

Overload for when the particle type defines a member variable.

Definition at line 108 of file primitives.hpp.

operator()() [2/4]

template<class T , std::enable_if_t< std::conjunction_v< std::negation< has_member_variable_state< T >>, std::negation< has_member_state< T >>, has_non_member_state< T >>, int > = 0>

constexpr decltype(auto) beluga::state_detail::state_fn::operator() ( T &&  t ) const

inlineconstexprnoexcept

Overload for when there is an external function that takes this particle type.

The non-member function must be in T's namespace so it can be found by ADL.

Definition at line 137 of file primitives.hpp.

operator()() [3/4]

template<class T , std::enable_if_t< std::conjunction_v< std::negation< has_member_variable_state< T >>, has_member_state< T >, std::negation< has_non_member_state< T >>>, int > = 0>

constexpr decltype(auto) beluga::state_detail::state_fn::operator() ( T &&  t ) const

inlineconstexprnoexcept

Overload for when the particle type defines a member method.

Definition at line 121 of file primitives.hpp.

operator()() [4/4]

template<class T , std::enable_if_t< std::conjunction_v< std::negation< has_member_variable_state< T >>, std::negation< has_member_state< T >>, std::negation< has_non_member_state< T >>, is_tuple_like< T >>, int > = 0, std::enable_if_t<(std::tuple_size_v< std::decay_t< T >> > 1), int > = 0>

constexpr decltype(auto) beluga::state_detail::state_fn::operator() ( T &&  t ) const

inlineconstexprnoexcept

Overload for tuple-like types.

Assumes that the first element is the state.
