TupleConstant¶
A tuple value built from its elements.
Declaration¶
Syntax¶
TupleConstant(expr* elements, ttype type)
Arguments¶
Argument |
Description |
|---|---|
|
the elements, in order. |
|
the tuple type of the result. |
Return values¶
The value of the expression.
Description¶
(a, b). A tuple has a fixed length and its elements may have different
types, which is what distinguishes it from a List.
Examples¶
(TupleConstant
:elements [
(IntegerConstant
:n 1
:type (Integer

(RealConstant
:r 2.0
:type (Real
:kind 4
)
)
]
:type (Tuple
:type [
(Integer
:kind 4
)
(Real
