Name
tuple_is_string_elemtuple_is_string_elemTupleIsStringElemTupleIsStringElem — Test whether the types of the elements of a tuple are of type
string.
Herror tuple_is_string_elem(const char* T, Hlong* IsString)
Herror T_tuple_is_string_elem(const Htuple T, Htuple* IsString)
tuple_is_string_elemtuple_is_string_elemTupleIsStringElemTupleIsStringElemTupleIsStringElem tests the elements of the input tuple TTTTt
separately.
For all elements of type string the value 1 (true) is returned in
IsStringIsStringIsStringIsStringisString, 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_string_elemtuple_is_string_elemTupleIsStringElemTupleIsStringElemTupleIsStringElem,
which can be used in an expression in the following syntax:
IsString := is_string_elem(T)
- Multithreading type: independent (runs in parallel even with exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
TTTTt (input_control) number(-array) → HTupleHTupleHtuple (string / real / integer / handle) (string / double / int / long / HHandle) (HString / double / Hlong / HHandle) (char* / double / Hlong / handle)
Input tuple.
Are the elements of the input tuple of type string?
tuple_is_string_elem ([3.1416,'pi',3], IsString)
* IsString = [false, true, false]
If the parameters are valid, the operator
tuple_is_string_elemtuple_is_string_elemTupleIsStringElemTupleIsStringElemTupleIsStringElem returns the value 2 (H_MSG_TRUE).
