Short description🔗

tuple_is_string_elemTupleIsStringElemTupleIsStringElemtuple_is_string_elemtuple_is_string_elem — Test whether the types of the elements of a tuple are of type string.

Signature🔗

tuple_is_string_elem( tuple T, out number IsString )void TupleIsStringElem( const HTuple& T, HTuple* IsString )static void HOperatorSet.TupleIsStringElem( HTuple t, out HTuple isString )def tuple_is_string_elem( t: HTupleType ) -> Sequence[int]

def tuple_is_string_elem_s( t: HTupleType ) -> intHerror tuple_is_string_elem( const char* T, Hlong* IsString )

Herror T_tuple_is_string_elem( const Htuple T, Htuple* IsString )

HTuple HTuple::TupleIsStringElem( ) const

HTuple HTuple.TupleIsStringElem( )

Description🔗

tuple_is_string_elemTupleIsStringElem tests the elements of the input tuple Ttt separately. For all elements of type string the value 11 (true) is returned in IsStringisStringis_string, else 00 (false) is returned.

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

IsString := is_string_elem(T)

Execution information🔗

Execution information

  • Multithreading type: reentrant (runs in parallel with non-exclusive operators).

  • Multithreading scope: global (may be called from any thread).

  • Processed without parallelization.

Parameters🔗

Ttt (input_control) tuple(-array) → (string / real / integer / handle)HTuple (HString / double / Hlong / HHandle)HTuple (string / double / int / long / HHandle)HTupleTypeHtuple (char* / double / Hlong / handle)

Input tuple.

IsStringisStringis_string (output_control) number(-array) → (integer)HTuple (Hlong)HTuple (int / long)Sequence[int]Htuple (Hlong)

Are the elements of the input tuple of type string?

Example🔗

(HDevelop)

tuple_is_string_elem ([3.1416,'pi',3], IsString)
* IsString = [false, true, false]

Result🔗

If the parameters are valid, the operator tuple_is_string_elemTupleIsStringElem returns the value 2 (H_MSG_TRUE).
