Struct template expression<expr_kind::terminal, hana::tuple< T >>

boost::yap::expression<expr_kind::terminal, hana::tuple< T >>

Synopsis

// In header: <boost/yap/expression.hpp>

template<typename T> 
struct expression<expr_kind::terminal, hana::tuple< T >> {
  // types
  typedef hana::tuple< T > tuple_type;

  // public member functions
  expression();
  expression(T &&);
  expression(hana::tuple< T > const &);
  expression(hana::tuple< T > &&);
  constexpr decltype(auto) value();

  // public data members
  static const expr_kind kind;
  tuple_type elements;
};

Description

Terminal expression specialization of the reference expression template.

Note

	Note
Due to a limitation of Doxygen, the `value()` member and each of the operator overloads listed here is a stand-in for three member functions. For each function `f`, the listing here is: return_type f (); However, there are actually three functions: return_type f () const &; return_type f () &; return_type f () &&;

Due to a limitation of Doxygen, the value() member and each of the operator overloads listed here is a stand-in for three member functions. For each function f, the listing here is:

return_type f ();

However, there are actually three functions:

return_type f () const &;
return_type f () &;
return_type f () &&;

`expression` public member functions

```
expression();
```
Default constructor. Does nothing.
```
expression(T && t);
```
Forwards t into elements.

expression(hana::tuple< T > const & rhs);

Copies rhs into the only data mamber, elements.

```
expression(hana::tuple< T > && rhs);
```
Moves rhs into the only data mamber, elements.
```
constexpr decltype(auto) value();
```
A convenience member function that dispatches to the free function value().
