Class template tuple

Class template tuple

boost::type_erasure::tuple

Synopsis

// In header: <boost/type_erasure/tuple.hpp>

template<typename Concept, class... T> 
class tuple {
public:
  // construct/copy/destruct
  template<class... U> explicit tuple(U &&...);
};

Description

tuple is a Boost.Fusion Random Access Sequence containing anys. Concept specifies the Concept for each of the elements. The remaining arguments must be (possibly const and/or reference qualified) placeholders, which are the placeholders of the elements.

`tuple` public construct/copy/destruct

```
template<class... U> explicit tuple(U &&... args);
```
Constructs a tuple. Each element of args will be used to initialize the corresponding any member. The binding for the tuple elements is determined by mapping the placeholders in T to the corresponding types in U.
