名称
tuple_type_elemtuple_type_elemTupleTypeElemTupleTypeElemtuple_type_elem — Return the types of the elements of a tuple.
参数签名
tuple_type_elem( : : T : Types)
Herror tuple_type_elem(double T, Hlong* Types)
Herror T_tuple_type_elem(const Htuple T, Htuple* Types)
def tuple_type_elem(t: HTupleType) -> Sequence[int]
def tuple_type_elem_s(t: HTupleType) -> int
描述
tuple_type_elemtuple_type_elemTupleTypeElemTupleTypeElemTupleTypeElemtuple_type_elem returns the types of the elements of the input tuple
TTTTtt. The types are returned separately as integer values in the output
parameter TypesTypesTypesTypestypestypes. In HDevelop the corresponding constants are
defined:
-
H_TYPE_INT (1).
-
H_TYPE_REAL (2).
-
H_TYPE_STRING (4).
-
H_TYPE_HANDLE (16).
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_elemTupleTypeElemTupleTypeElemTupleTypeElemtuple_type_elem,
which can be used in an expression in the following syntax:
Types := type_elem(T)
运行信息
- Multithreading type: independent (runs in parallel even with exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
参数表
TTTTtt (input_control) tuple(-array) → HTupleHTupleTypeHTupleHtuple (real / integer / string / handle) (double / int / long / string / HHandle) (double / Hlong / HString / HHandle) (double / Hlong / char* / handle)
Input tuple.
TypesTypesTypesTypestypestypes (output_control) number(-array) → HTupleSequence[int]HTupleHtuple (integer) (int / long) (Hlong) (Hlong)
Types of the elements of the input tuple as integer values.
例程 (HDevelop)
tuple_type_elem ([3.1416,'pi',3], Types)
* Types = [H_TYPE_REAL, H_TYPE_STRING, H_TYPE_INT]
结果
If the parameters are valid, the operator
tuple_type_elemtuple_type_elemTupleTypeElemTupleTypeElemTupleTypeElemtuple_type_elem returns the value 2 (
H_MSG_TRUE)
.
