Tuple-Like

Description

A type models Tuple-Like if its instances are fixed-length heterogeneous sequences of objects of specified types, and if it provides specializations or overloads of the accessor templates tuple_size, tuple_element and tuple_get (see below).

Associated Types

Notation

`T`	-	A type which is a model of Tuple-Like
`t`	-	Object of type `T`
`N`	-	Integral constant expression

Valid Expressions / Semantics

Expression	Expression Type	Semantics
`boost::io::tuple_size<T>::type`	Integral constant expression	Returns the number of elements in `t`
`boost::io::tuple_element<N, T>::type`	The type of the `N`^th element of `t`	-
`boost::io::tuple_get<N>(t)`	If `t` is mutable, a type whose instances are implicitly convertable to `tuple_element<N, T>::type` and which may be assigned objects of type `tuple_element<N, T>::type` `const tuple_element<N, T>::type&`, otherwise	Returns an object suitable for accessing the `N`^th element of `t`

Models

std::pair.
boost::tuple.
boost::array.
