tuple_is_handle_elemT_tuple_is_handle_elemTupleIsHandleElemTupleIsHandleElem (Operator)
Name
tuple_is_handle_elemT_tuple_is_handle_elemTupleIsHandleElemTupleIsHandleElem — Test whether the elements of a tuple are of type handle.
Signature
Herror T_tuple_is_handle_elem(const Htuple T, Htuple* IsHandle)
Description
tuple_is_handle_elemtuple_is_handle_elemTupleIsHandleElemTupleIsHandleElemTupleIsHandleElem tests the elements of the input tuple TTTTt
separately.
For all elements of type handle the value 1 (true) is returned in
IsHandleIsHandleIsHandleIsHandleisHandle, 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_elemTupleIsHandleElemTupleIsHandleElemTupleIsHandleElem,
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) → HTupleHTupleHtuple (handle / real / integer / string) (HHandle / double / int / long / string) (HHandle / double / Hlong / HString) (handle / double / Hlong / char*)
Input tuple.
IsHandleIsHandleIsHandleIsHandleisHandle (output_control) number(-array) → HTupleHTupleHtuple (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_elemTupleIsHandleElemTupleIsHandleElemTupleIsHandleElem returns the value 2 (H_MSG_TRUE).
