Tuples¶
Predefined Functions on Tuples.
Tuples are a predefined structured type in Chapel. They are specified in the Tuples chapter of the Chapel Language Specification. This page lists the predefined functions on tuples. They are always available to all Chapel programs.
Besides the functions defined here, the Chapel Language specification defines other operations available on tuples: indexing, iteration, assignment, and unary, binary, and relational operators.
-
proc
tuple.
size
param¶ Returns the number of components of the tuple.
-
proc
tuple.
indices
¶ Returns the range of indices that are legal for indexing into the tuple:
0..<this.size
.
-
proc
isTupleType
(type t) param¶ Returns true if its argument is a tuple type. The argument must be a type.
-
proc
isHomogeneousTupleType
(type t) param¶ Returns true if its argument is a homogeneous tuple type. The argument must be a type.
-
proc
max
(type t): t¶ Returns a tuple of type t with each component set to
max
of the type in the corresponding component of the argument.
-
proc
min
(type t): t¶ Returns a tuple of type t with each component set to
min
of the type in the corresponding component of the argument.
