Copy constructor.

If OWNING copy the resources

inline ~Tuple()

Destructor.

inline Tuple &operator=(const Tuple &other)

Assignment operator.

Constructors from variants

Constructors from ampl::Variant objects.

inline Tuple(Variant v1)

inline Tuple(Variant v1, Variant v2)

inline Tuple(Variant v1, Variant v2, Variant v3)

inline Tuple(Variant v1, Variant v2, Variant v3, Variant v4)

Construct tuples from variants.

Parameters:

• v1 – First element

• v2 – Second element

Public Functions

inline explicit Tuple(AMPL_TUPLE *other)

Construct a tuple from an internal struct (infrastructure).

inline std::size_t size() const

Get the number of Elements in this tuple.

inline std::string toString() const

Return a string representation of this tuple.

All elements are formatted as in BasicVariant::toString and comma separated. An empty tuple is returned as “()”.

inline Variant operator[](std::size_t index) const

Accessor for elements of the tuple.

Public Static Functions

static inline Tuple join(Tuple t1, Tuple t2)

Join two tuples together and forms a new one copying all data.
