tuple_type_elemtuple_type_elemTupleTypeElemTupleTypeElemtuple_type_elem (Operator)
Name
tuple_type_elemtuple_type_elemTupleTypeElemTupleTypeElemtuple_type_elem — Return the types of the elements of a tuple.
Signature
tuple_type_elem( : : T : Types)
Herror tuple_type_elem(double T, Hlong* Types)
Herror T_tuple_type_elem(const Htuple T, Htuple* Types)
def tuple_type_elem(t: HTupleType) -> Sequence[int]
def tuple_type_elem_s(t: HTupleType) -> int
Description
tuple_type_elemtuple_type_elemTupleTypeElemTupleTypeElemtuple_type_elem returns the types of the elements of the input tuple
TTTtt. The types are returned separately as integer values in the output
parameter TypesTypesTypestypestypes. In HDevelop the corresponding constants are
defined:
-
H_TYPE_INT (1).
-
H_TYPE_REAL (2).
-
H_TYPE_STRING (4).
-
H_TYPE_HANDLE (16).
Exception: Empty input tuple
If the input tuple is empty, the operator returns an empty tuple.
HDevelop In-line Operation
HDevelop provides an in-line operation for tuple_type_elemtuple_type_elemTupleTypeElemTupleTypeElemtuple_type_elem,
which can be used in an expression in the following syntax:
Types := type_elem(T)
Execution Information
- Multithreading type: independent (runs in parallel even with exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
Parameters
TTTtt (input_control) tuple(-array) → HTupleHTupleTypeHTupleHtuple (real / integer / string / handle) (double / int / long / string / HHandle) (double / Hlong / HString / HHandle) (double / Hlong / char* / handle)
Input tuple.
TypesTypesTypestypestypes (output_control) number(-array) → HTupleSequence[int]HTupleHtuple (integer) (int / long) (Hlong) (Hlong)
Types of the elements of the input tuple as integer values.
Example (HDevelop)
tuple_type_elem ([3.1416,'pi',3], Types)
* Types = [H_TYPE_REAL, H_TYPE_STRING, H_TYPE_INT]
Result
If the parameters are valid, the operator
tuple_type_elemtuple_type_elemTupleTypeElemTupleTypeElemtuple_type_elem returns the value 2 (
H_MSG_TRUE)
.
