Defined in header <tuple>
template< class... Types > class tuple;		(since C++11)

Class template std::tuple is a heterogeneous fixed-size collection of values. It is a generalization of std::pair.

[edit] Member functions

(constructor)	constructs new tuple (public member function)
operator=	assigns the contents (public member function)
swap	swaps the contents (public member function)

[edit] Non-member functions

make_tuple	creates a tuple object of the type defined by the argument types (function template)
tie	creates a tuple of lvalue references or unpacks a tuple into individual objects (function template)
forward_as_tuple	creates a tuple of rvalue references (function template)
tuple_cat	creates a tuple by concatenating any number of tuples (function template)
get	accesses specified element (function template)
operator== operator!= operator< operator<= operator> operator>=	lexicographically compares the values in the tuple (function template)
std::swap(std::tuple) (C++11)	specializes the std::swap algorithm (function template)

[edit] Helper classes

tuple_size	obtains the size of tuple at compile time (class template specialization)
tuple_element	obtains the type of the specified element (class template specialization)
std::uses_allocator<std::tuple> (C++11)	specializes the std::uses_allocator type trait (class template specialization)
ignore	placeholder to skip an element when unpacking a tuple using tie (constant)
