Struct template expression

boost::yap::expression

Synopsis

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

template<expr_kind Kind, typename Tuple> 
struct expression {
  // types
  typedef Tuple tuple_type;

  // construct/copy/destruct
  expression();
  expression(tuple_type &&);

  // public member functions
  decltype(auto) constexpr value();
  decltype(auto) constexpr left();
  decltype(auto) constexpr right();

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

Description

Reference expression template that provides all operator overloads.

Note

	Note
Due to a limitation of Doxygen, each of the `value()`, `left()`, `right()`, and 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, each of the value(), left(), right(), and 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 construct/copy/destruct

```
expression();
```
Default constructor. Does nothing.
```
expression(tuple_type && rhs);
```
Moves rhs into the only data mamber, elements.

`expression` public member functions

```
decltype(auto) constexpr value();
```
A convenience member function that dispatches to the free function value().
```
decltype(auto) constexpr left();
```
A convenience member function that dispatches to the free function left().
```
decltype(auto) constexpr right();
```
A convenience member function that dispatches to the free function right().
