tuple_is_handle_elemT_tuple_is_handle_elemTupleIsHandleElemTupleIsHandleElemtuple_is_handle_elem — Test whether the elements of a tuple are of type handle.

Signature

tuple_is_handle_elem( : : T : IsHandle)

Herror T_tuple_is_handle_elem(const Htuple T, Htuple* IsHandle)

void TupleIsHandleElem(const HTuple& T, HTuple* IsHandle)

HTuple HTuple::TupleIsHandleElem() const

static void HOperatorSet.TupleIsHandleElem(HTuple t, out HTuple isHandle)

HTuple HTuple.TupleIsHandleElem()

def tuple_is_handle_elem(t: HTupleType) -> Sequence[int]

def tuple_is_handle_elem_s(t: HTupleType) -> int

Description

tuple_is_handle_elemtuple_is_handle_elemTupleIsHandleElemTupleIsHandleElemtuple_is_handle_elem tests the elements of the input tuple TTTtt separately. For all elements of type handle the value 1 (true) is returned in IsHandleIsHandleIsHandleisHandleis_handle, else 0 (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_handle_elemtuple_is_handle_elemTupleIsHandleElemTupleIsHandleElemtuple_is_handle_elem, which can be used in an expression in the following syntax:

IsHandle := is_handle_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 (handle / real / integer / string) (HHandle / double / int / long / string) (HHandle / double / Hlong / HString) (handle / double / Hlong / char*)

Input tuple.

IsHandleIsHandleIsHandleisHandleis_handle (output_control)  number(-array) → HTupleSequence[int]HTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Boolean values indicating if the elements of the input tuple are of type handle.

Result

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