The TR1 Tuple type provides a default constructor, a constructor that takes initializers for all of its elements, a copy constructor, and a converting copy constructor. The details of the various constructors are described in this section.
Notation
T1 ...
TN, U1
... UNTuple element types
P1 ...
PNParameter types
Ti, Ui
The type of the ith
element of a tuple
Pi
The type of the ith
parameter
tuple();
Requirements: Each Ti
is default-constructible.
Semantics: Default initializes each element of the tuple.
tuple(P1,P2,...,PN);
Requirements: Each Pi
is Ti if Ti is a reference type, const Ti& otherwise.
Semantics: Copy initializes each element with the corresponding parameter.
tuple(const tuple& t);
Requirements: Each Ti
should be copy-constructible.
Semantics: Copy constructs each element
of *this
with the corresponding element of t.
template<typename U1, typename U2, ..., typename UN> tuple(const tuple<U1, U2, ..., UN>& t);
Requirements: Each Ti
shall be constructible from the corresponding Ui.
Semantics: Constructs each element of
*this
with the corresponding element of t.
