tuple_type_elemtuple_type_elemTupleTypeElemTupleTypeElem (Operator)

Name

tuple_type_elemtuple_type_elemTupleTypeElemTupleTypeElem — 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)

void TupleTypeElem(const HTuple& T, HTuple* Types)

HTuple HTuple::TupleTypeElem() const

static void HOperatorSet.TupleTypeElem(HTuple t, out HTuple types)

HTuple HTuple.TupleTypeElem()

Description

tuple_type_elemtuple_type_elemTupleTypeElemTupleTypeElemTupleTypeElem 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:

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_elemTupleTypeElemTupleTypeElemTupleTypeElem, which can be used in an expression in the following syntax:

Types := type_elem(T)

Execution Information

Parameters

TTTTt (input_control)  tuple(-array) HTupleHTupleHtuple (real / integer / string / handle) (double / int / long / string / HHandle) (double / Hlong / HString / HHandle) (double / Hlong / char* / handle)

Input tuple.

TypesTypesTypesTypestypes (output_control)  number(-array) HTupleHTupleHtuple (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_elemTupleTypeElemTupleTypeElemTupleTypeElem returns the value 2 (H_MSG_TRUE).
